New Antenna for FM Radio

 I've had this FM Radio Halo Antenna for a couple of years, and had it hanging in the garage for my "Shop Radio". I didn't think it worked very well, so I used a vertical whip on a magnetic mount. 

I had some whips, NMO coils, and a magnetic mount "in stock and on hand", so I picked a combination that would work acceptably for the frequency range of 88MHz to 108MHz.

You've seen these before, I'm sure. That's it, the black rectangular thing (the mag mount base) next to the coil of wire, with a grey cone and a whip on it.

That was OK, but I decided to make a "folded dipole" antenna and try that. The dipole has some broadside "gain", which allows me to receive the weaker stations to the South down by Denver compared to the vertical.

This is a *very* simple antenna to make; just some wire, and a little 300 Ohm to 75 Ohm "balun" transformer to convert the 300 Ohm BALanced impedance of a folded dipole to the 75 Ohm UNbalanced coax input of the radio.

Took about 45 minutes to measure and cut the wire, solder on the balun, make and install the coax, and staple it to the drywall.

This works much better than either the halo antenna or the whip antenna, in this situation, and now the stations to the South come in stronger, and the receiver locks on the stereo signal better than it did before.

But I still had this halo antenna for the FM band, and a coax going through the foundation into the basement workshop.

Sooooo....needing a better antenna for the nice FM stereo in the basement, I dug the halo out of storage, and addressed the shortcomings it had for outdoor use here. I took it apart, cleaned all the areas that got bolted together with ScotchBrite and alcohol, then reassembled it with some Jet Lube copper-based anti-seize compound. Then I made a bracket for it out of some aluminum angle, cleaned all the parts again, assembled it all, and shot it with a coat of self-etching primer. After that cured, I painted it with some of the Rust-Oleum "Truck Bed Liner" paint I had, and put it in the sun to bake. The Jet Lube will stop any oxidization, and the heavy coat of the bed liner should seal the connections from moisture.

So here it is, hanging on my mount from the eaves.

And you cab barely see it from the street, so SLW won't squawk too loudly.

The messy coax install will be cleaned up as soon as I find my "Coax Nails" in the correct size.

I have ones for larger coax, but can't find my box of RG-6 size ones. 

And yes, I saw them last week while rummaging around for something else. Next time I see them, they'll get put with all the other 75 Ohm coax stuff I have.

So how does it work? Wellllll.....pretty "meh" to the South as it's on the North side of the house, below the roofline. Some of the stations I received before in the basement on the whip are weaker with this antenna, which I thought might be the case. Stations to the North come in stronger, but there's not much out that way that isn't "local", so it's a net loss of coverage.

I may wind up fabricating one of my favorite antennas for the FM Band, a simple quarter-wave vertical. I'd build an FM Band Lindenblad, but SLW might not be too happy with that.....

 

 

 

Hectic Two Days

 Well.....SLW was in Austin visiting a friend, did a trip-and-fall at a venue they were at on Sunday, and wound up in the ER with two broken bones at her arm/wrist junction. The Doctors in the ER took X-Rays, pronounced she had two broken bones, and then splinted it, wrapped it, gave her a few painkillers and an Rx for some additional ones, and sent her on her way.

She toughed it out Sunday night and Monday, but changed her flight to the earliest one she could get on Tuesday. Every bump, jiggle, and bounce on the ride back made her wince, and she cried in pain a couple of times, as the few pills she was able to get from the pharmacy wore off.

We spent most of  today at the Orthopedic Clinic, getting more detailed X-Rays, and some consultation. She's going in Monday morning for surgery to realign things, and install a plate and two screws to hold things in position while the bones knit back together. It's outpatient surgery, and she'll be home in the afternoon. I never thought I'd ever hear her say "Thank GOD for Percocet", but then I've never seen her in that kind of pain.

Son had two days of orientation and training at his new company's place in Denver, and he was out in the field today, all day. He'll be working out of Greeley, and today they were down by Fort Lupton on Weld 19 flagging for a company upgrading the electric service to the area. Tomorrow they'll be in Broomfield doing the flagging for a repaving job off 287. So far he likes it (one day?), and he's getting the same pay as he was making in Lost Angeleez, with about 1/10th the stress, so he thinks it's a good trade.....so far!

The Little Guy with the New Little Guy

 Sweet Little Wife sent this. She's been babysitting both of them while The Kids are at work.

Maybe there's some hope for the future after all.....

Have a blessed Sunday!

Space Weather for the Weekend

 And it looks like cycle 25 is off and running.

The forecast from Dr. Skov is below:

Yeah, she can be 'over the top' a bit, but she's got gen-you-ine creds and degrees and she knows her stuff.

Solar Flux should be in the low 90's for the weekend, with some good band openings.

I've noticed more Ionospheric Sounders in operation on the 20 Meter (14MHz) band than usual, and I've even see a few on the 40 Meter (7MHz) band.

I've been hearing Danie, ZS3D, in South Africa on 40 Meters on a regular basis, and that's getting me fired up to put my big 33' vertical back up. It's a full quarter-wave on 7MHz, and with the elevated radials, works extremely well.

Saturday Night Music

 One of my favorite songs, from one of my favorite bands, featuring one of my favorite guitar players.

It was also written specifically for one of my favorite TV shows, Miami Vice.

Hope you're having a great weekend. Really getting to be Fall here, with temps dropping into the low 40's at night.

Dead Juniper Removal - Part Deux

 Removing the dead junipers in the back yard came to a screeching halt earlier this year when my shoulder went on strike. I had some kind of big "knot" in the muscle that you could feel moving around when I moved my arm around. My Doctor ordered an ultrasound, which came back negative, the findings being "No Solid or Cystic Mass Found". 

Sooooo....off to Physical Therapy for 8 weeks, during which time the "knot" got smaller and less painful. It's still there, but not nearly as annoying as it was.

I still can't do a lot of the yard work I started off doing early this year, even if I take it pretty easy. I'm still having issues with getting lightheaded at times (hah....what's new, eh?), and my BP bounces around a lot, with the "Irregular Heartbeat" icon popping up almost every time I measure my BP. I have an appointment with my Cardiologist next month, and we'll see what he makes of the readings from the "ZIO Patch" I wore for two weeks.

ANYWAY.....now that my son is here, he's been helping out a lot with these things, and today he and SLW went bonkers on the junipers in the back yard.

They cleared out all the dead stuff back in Pebbles' "forest":

And then attacked the dead grove of them out on "The Point":

Sorry the pix are kinda blown-out. I'm so used to popping up the little flash on the camera, I did it out of habit, making the camera switch exposure modes.

I'll help with the raking up, and feed the apple tree in the background, later today when it cools down. I can't do too much more than light work when it's over 90*, so this is part of my "Taking It Easy" when I'm doing yard work, and it's also put a major crimp in working on the Toyota....

9-11 And I Feel "Empty".....

 That's about the only way I can describe it. All the blood, treasure, and broken lives served no purpose, other than to enrich some, and destroy others.

But they weren't the "others" we set out to destroy.

I'm greatly saddened by the astoundingly poor judgement shown in the recent "withdrawal" from the 'Stan. Grade school kids could have done better with minimal coaching. How do you even categorize this? "Withdrawal" is too nice a word, and so is even "Retreat". To "retreat" at least implies and orderliness to it. I don't even know if there's a single word that describes what happened. "Abandonment" is about all I can come up with. "Wanton and Willful Abandonment" doesn't even sound strong enough to describe the cowardly actions that took place.

Anyway.....we went to the Rist Canyon Mountain Festival today, a benefit for the Rist Canyon Volunteer Fire Department. It was great to see all the people there, without masks, enjoying the sunshine, music, food, and demonstrations put on by the RCVFD, Larimer County Sheriff, and the UC Health Lifeline helicopter crews. BTW, Helicopter N68RX is one of the choppers I see flying over regularly.

And a little girl did a bang-on rendition of our National Anthem. The canyon got quiet, she sang her little heart out, and there wasn't a hat on a head, or a dry eye.

When we returned home, we had the neighborhood block party to attend, and catch up with neighbors we hadn't seen in a while. SLW was marveling at the fact that NO permits, permissions, or regulations were required. They just coned off the street, set up the BBQ and some tables, and everybody brought a side dish.

A splendid time was had by all, and we're looking forward to TLG being here Sunday/Monday, as usual. His new little brother came home from the hospital after 80 days, and is doing extremely well. From the rate he's growing and gaining weight, I have a hunch he's gonna be a bruiser!

So life goes on, for now, and I hope you have a blessed Sunday.

Another Interesting Flight Path, But At Night This Time.

 I suppose with all the "Multi-Spectral" sensors out there these days, it doesn't matter much what time of day you do your mapping flights.

This is the first time I've seen one after sundown, though,

I Gots Nuttin'....

 Quiet week....

Took my son to the airport Tuesday, and he headed back to Lost Angeleez to get the rest of his stuff. He'll stay in St. George tonight, and then head up through Salt Lake, and East to Cheyenne, and South to here.

SLW came back last Sunday from a trip to see some friends in Oklahoma, which made two trips to DIA this week. Oh well, at least a good highway run helps keep my engine oil cleaner than just putting around town.

And I have a whole stack of things I dragged up from the basement so I can take pix of them, and list them on eBay. Been cleaning out Der Boonker, and found a lot of stuff I'll never use, lost interest in, or had had doubles/triples of, so that stuff's going out, too.

I really don't need seven scanners here in NoCo, where one is sufficient. And I'll be thinning back the Heathkit Herd shortly, too. It was fun having the stuff for "Show and Tell" back in SoCal, but the Ham Community is completely different here, and I haven't found more than a couple of people I share interests with. I really don't need five Heathkit Shortwave receivers, either.

I finished getting the SB-401 transmitter back together, tested, and aligned, so that one and the matching SB-301 receiver will go on the block, too. That pair was an impulse buy one night, and while it was fun to rebuild them, using them on-the-air isn't a "1969 Time Machine", but then I suspected that. A 50 year old single-conversion receiver with fixed selectivity gives the results I expected. Fun to play with and use casually, but a bit lacking when the going gets tough.

Have a good three-day weekend, and you can put away the white belt and shoes now....

Oh, No......Tear It Apart Again?

 WELL.......seems I miscalculated a bit when it came to measuring the the rack space I had for the new(er) TEAC A-4300SX tape deck.

It was a bit over 1/8" too tall to fit into the available space, so everything came off the shelf above, and I raised it about 2".

Now it even has enough room for an even bigger deck, with 10.5" reels, should I so desire.

 And since the Pioneer receiver had never been given a proper cleaning since I bought it, I dove into that.

Think I can handle this?

 

It was  more than a bit grungy inside:

 

 

I'm amazed at the amount of dirt all over this tuning capacitor:

 

And in other places:

Very clean under the bottom plate:

And I pulled the front panel off, as there was a motley collection of "dirt" on the dial and the backside of the glass, which just drove me NUTZ.

It took about 30 minutes with the shop vacuum and a soft bristled brush to knock all the splooge off the internals and vacuum it out, and another half hour or so to clean the dial assembly. Then I spent an hour or so cleaning the aluminum front panel, and another hour cleaning and buffing the knobs.

All back together and shiny again:

And here's the finished (for now...) rack, all back together (for now...) and playing beautifully.

Hope y'all have a great weekend. I have to shuttle down to DIA to pick up SLW who was visiting a friend for the last week. Spent a lot of good "Garage Time" with my son just hanging out and discussing Guy Stuff.

TEAC A-4300SX Wrap-Up

 This one was easier than the A-4010SU I did last month. It's a 10 year newer design, the chassis is more rugged, all of the oil-filled capacitors (aka the "Suzuki Firecrackers") have been replaced with newer film capacitors, and the electronics are completely new.

This picture is how it looked out-of-the-box. BTW, this was just about the best packed item I've ever received via eBay. Double-boxed with new styrafoam inserts, and extra cardboard under the seams so when you opened it up you didn't damage anything.

The reddish dust was from a blanket I temporarily used to cover it up. Entirely my fault, and bit of extra cleaning to do.

SUPER clean inside.

And all you have to do to access the monitoring/adjustment points in the electronics is to lay it on it's back, remove two screws, and slide off the bottom cover.

And TEAC even used a nice label on the inside of the bottom cover showing where all the points are.

And even though their Technical "checked" the belts and pronounced them "OK", I went ahead and replaced them anyway. They felt "sticky" to me, and that usually means they're degrading, and I had them, so new ones went in, along with cleaning the entire tape path, and demagnetizing all the bits. The counter belt required pulling the tape reel hub to get at, but it was just two setscrews. The capstan belt required removing three large screws and lifting a support brace out of the way, but it was far easier to do than the other deck, where I had to remove screws from the bottom of the chassis so I could lift out the entire capstan assembly to get at the belt.

The flat, gold colored brace running vertically in the picture comes off, and you can easily swap the belt.

 And it's a good thing I replaced the belts because the two setscrews on the reel hub, and the three screws holding the bottom of the capstan, were loose. Barely more than "finger tight", and could have easily caused problems down the road. Makes me wonder if they removed the belts to inspect them, put them back on, and never fully tightened the screws. Which begs the question..."New belts are only $10. Why didn't you change them?"....

And to finish it off, I cleaned and oiled the wood trim sides.

SO...it's all back together, and I'll post a pic after I lug it done to the workshop and get it in the rack..

And now I have a really nice A-4010SU to sell.......

Three Score and Ten

Well, I've made it around the Sun 70 times now, although somewhat worse for the wear. Got the results back from the 14 days I wore the cardiac monitor, and it confirms that I've got a lot of "missing" heartbeats caused by Premature Ventricular Contractions. Depending on what my Cardiologist says, it could be as simple as cutting down on coffee intake, to taking medication, to getting a pacemaker installed. I'm supposed to hear from them by Friday, if not I'll give them a call on Monday.

As the memes all say, it was a H3ll of a lot more fun being 20 in the 70's than being 70 in the 20's. If I tried half the stuff I did back then, I don't think I'd last more than a couple of weeks. I used to go blasting along in excess of 160MPH, and now I turn the radio down when traffic gets heavy.

No plans for the day other than waiting for the TEAC to get here, along with a set of belts for it. The listing said their Tech looked at it and pronounced the belts to be "fine", which either means they were replaced at some point, or the Tech doesn't know what he's doing. TEAC belts of that vintage tend to get soft, gooey, gummy, and disintegrate, leaving a mess inside the machine. I was lucky in that the belt in the 4010 deck had broken and was laying in the case, but I've seen pix showing the belts to be a ball of goo wrapped around the pulleys. Regardless, I have new belts for it, they're easier to change than on the other deck, and I'll swap them out when I have it opened up to inspect/service things.

Might go out for dinner tonight, might not. We're expecting some heavy thunderstorm activity later today, so we might just sit it out. Have a birthday party for one of the clan's young-uns on Saturday, and that should be fun seeing the rest of the clan, and just hanging out.

Enjoy the upcoming weekend!

 

Newest Acquisition

 This guy:

 Should be here later this week. It's another TEAC, an A-4300SX, and is ten years newer than the one I picked up last month. "If I Woulda Known..." last month what I know now about TEAC tape machines, I most likely would have passed on the A-4010SU I bought, and gone right to this one. The mechanical bits are 90% the same, as it's still a TEAC "A-4xxx Series" machine, but it has significantly updated electronics, and better heads. It also has switches to adjust the Recording Bias, and Playback Equalization, allowing the use of newer formulation tapes, like the "Type @ Low Noise" tapes, and the "Type 3 High Output" tapes, sold as "LN", and "UD" from companies like Maxell. All I used before on my big Sony deck was Maxell tape, and it was significantly better than the Type 1 tape. "Type 1" tapes are the reddish-brown tapes, and "Type 2" and "Type 3" tapes are almost always the dark grey colored tape, owing to the use of a different oxide coating.

And speaking of heads, they heads on this one look to be in excellent condition:

 

While my A-4010 shows definite signs of wear. They don't have any grooves in them, but show a definite wear pattern:

But way better than this one (photo courtesy of OakTreeVintage.com):

Now THAT'S a "groovey" tape head! I've seen machines advertised on eBay where the seller says "Plays and records fine, and sounds GREAT!", and then shows a picture of the heads worn this bad.

Uhhhhh.....no.

Anyway.....In the last month I've brought myself up-to-speed on the current state of analog magnetic recording, and found a great website with loads of information on the TEAC product line, complete with specifications, and reviews. They also cover every tape machine I've heard of, and a lot more I didn't know existed, or were too specialized/expensive for me back in the day. Eventually I want to "work my way up" to a TEAC 6000 series or 7000 series, but they're out of my budget range for now.

Been Keeping Busy....

 Went to see the "Toughest Monster Truck" show down at the Larimer County Fairgrounds, aka "The Ranch". I've been to lots of different motorsports events, but this was a first.

Good Gravy those things are LOUD. 500 cubic inches of Big Block Chevy, with a blower, running in an enclosed arena, can make quite a bit of racket through open exhaust. Glad I brought my Peltor muffs!

With Riverrider in mind, I post this:

Swiped from FakeBook, and of course the "Fact Checkers" had a field day with it.

We got some sprinkles, and 15 miles East of here got clobbered with ping-pong ball sized hail. Glad it missed us, but hope WSF got through it OK, as it was headed his way..

Have a good weekend!

Looks Like These Survey Flights Are Common.

 This one's out East of here.

This is what caught my eye.

This is a "light" day for air traffic. There's times I've seen sixty aircraft in the area I can monitor.

Another Survey Flight

 By the contractor folks at MARC. Their Mission Statement indicates...

"MARC is North America's largest provider of specialized contract aircraft and flight crews for airborne GIS, survey and surveillence projects. MARC provides the industry a modified fleet of Navajos, Navajo Chieftains and Merlin turbine aircraft, equipped and ready for deployment. Each aircraft is configured for all GIS applications including imagery and LiDAR installations."

These are probably common, but since I've only had the decoder running since June, they're "new" to me.

These are the various payloads they operate: http://www.marcflightservices.com/sensor.html

Glad That's Over.....!

 Got the Radio Room fan installed on Sunday, and the Dining Room fan installed today.

The RR fan is a Hunter, and was made and packaged better, with FAR better instructions, than the DR fan.

Radio Room:

I have two of the three bulbs loose in the socket as otherwise it's too bright. That'll do until I either get some lower wattage bulbs, or a dimmer installed.

Dining Room:

This one was made by "Parrot Uncle" (who?) and had cheaper hardware, a weird angled ceiling mount which involved some re-engineering of the hardware, and the lamps are type "G-10" LED, and a royal PITA to get installed in the sockets. It's a two-pin lamp base that looks like an old florescent lamp starter can, and they barely fit in the socket.

BUT.....they're hung, they work, and SLW is happy with them.

Homeowner Stuff....

 Had my son help me remove the ceiling light fixture in the Radio Room here, and then we replaced it with a combo fan/light. It gets uncomfortably warm back here in the Summer on sunny days, and the little room fan I propped up on the chest freezer in here was inconvenient.

Got one of the these "Hunter" fans from the HD store....

I also have another one to hang in the dining room, but it's a bit different, and made by a different company. They're both chinesium, but represent different points in the price spectrum. The Hunter fan was very nicely packed, with good quality, good sized hardware, and a very good instruction booklet that helped a first-time-fan-hanger get the project finished.

The other fan was packed with very cheap styrofoam, the kind that crumbles when you look at it, some of the hardware is chintzy, and the instruction book has errors in it, which could have thrown me if I hadn't installed the Hunter fan first.

The really annoying thing is that the Hunter was about half the price of the the other one.

Son is getting settled in and decompressing a bit from the trip. He'd like to find some kind of job in "Transportation", perhaps driving a Pilot Car, or maybe some warehouse work. He starts looking in earnest on Monday, even if we have to start prodding him. He and TLG have hit it off, and Pebbles was ecstatic to see somebody from the Old Hood show up....

The NLG is almost up to 6 pounds, and has been off Supplemental O2 for a bit, but was put back on it yesterday. Not sure when he'll be released to go home, but the Doctors are very happy with his progress.

Another "Interesting" Flight Path -Updated A Bit-

 The aircraft is registered to the National Science Foundation.

I'll have to look on google maps to see what's down there....

This is a profile of the aircraft at an Open House. Picture below.

More info from Wikkipedia regarding this Gulfstream V aircraft:

On March 11, 2005, Gulfstream delivered an ultra-long-range G-V to the National Center for Atmospheric Research (NCAR). The aircraft—known as the High-performance, Instrumented Airborne Platform for Environmental Research (HIAPER), based in Boulder, Colorado, is being used by environmental and atmospheric scientists from both public and private research facilities.^[19] The GV was chosen by NCAR for its exceptionally high cruising altitude, long range, endurance, payload, reliability, and low operating costs, as well as worldwide product support.^[20] The HIAPER Gulfstream V is modified to accept wing/pylon mounted instrumentation. 

 

And gee....it has Hardpoints on the wings, too!

The "Prodigal Son" Is Almost Home

 Well my son surprised me, and probably Well Seasoned Fool, too.

Rather than take either the "approved" detour, or WSF's more Southerly path, he just stayed on CO-13 North until it turned into WY-789, and he'll pick up I-80 East about 25 miles West of Rawlins, WY. From there it's a straight shot to Cheyenne, and then I-25 South to here.

Good naviguessing, kid! We didn't think of that.....and we live here!

TEAC A-4010SU -Take Two-

 Well, thanks to some answers from the guys on the Audio Science Review forum, I was able to "fix" the deck so it runs at correct speed.

Turns out there are two steps on the motor pulley, that match the two steps on the capstan/flywheel assembly.

This is the 50Hz position, where I had the belt installed:

And this is the 60Hz position after I corrected my error:

 

 

See how the belt is now "down further" than in the first pic? Yup, changes the drive ratio between the capstan motor and the capstan/flywheel assembly. I didn't know that TEAC provided the ability to run this machine on either 50HZ or 60Hz. It's not mentioned in the Service Manual, and this machine was sold as strictly "115V/60Hz". The "U" in the model number means it was made to be sold to US Service personnel stationed overseas. Pioneer and Sony did the same thing, but having "missed out" on the whole BX/PX (which is it these days?) experience, I had only a fuzzy knowledge of the items you could buy at a substantial savings over what we'd pay for the (mostly) same item in the States. It's nice that TEAC let this design element stay in these purpose-built machines for those times you needed to run on a different power line frequency.

The original drive belt was in three pieces, and I cleaned both pulleys without making a note of which of the two sets were dirty from the belt. Oooops! And then I didn't look closely enough to see that 1) There's TWO sets of pulleys, and 2) ONE of the sets had some wear marks on it making it easy to see (if you LOOK) which set was used. If you look at the aluminum pulley in the top picture, you can see it has some wear marks on it, indicating the belt was riding on it. I though it a bit "curious" that the pulley I was putting the new belt onto looked pristine, while the other step below it didn't. That's a big D'OH! on me, and a rookie mistake that I should have caught. As a Wise Old Mechanic once told me, and it's been excellent advice in my career, "You Have To Learn How To Hear What The Parts Are Telling You".

Anyway, back to the deck.....

It's all put back together, and all the pre-recorded tapes The Colonel gave me, including the Bob Hope USO Show, sound amazing. All I can find so far is that Mr. Hope was there in 1969, 1970, 1972. Now I'll try and nail it down to only those shows with Raquel Welch, and I'll have a better idea. SLW wants to listen to the entire tape. The quality of the recording is excellent. It was recorded with perfectly balanced levels, and you can hear every.single.word the performers say. It's like being on-stage with the. It sounds like it was recorded directly out of the mixing board.

UPDATE ON SON'S CALEXIT

He's spending the night in Grand Junction. Thursday is going to be a long day because of the detours. Thanks to Well Seasoned Fool, he now has a much better alternate route than what he was being fed getting from Google Maps. It adds some miles, but I'm assured it will be a better way for him to do the last leg of his exfiltration.

OUCH! I-70 Closed Until October, Son Gets Detoured.....

 He was going to come on the Southern Route, taking I-40 through AZ and NM. Well....he changed his mind, and was planning on taking I-70 through CO to get here.

As the headline says, I-70 is closed due to mudslides and other weather-related issues. Google Maps is telling him to take the 13 North out of Rifle up to the 40, and then come across and down to Denver, and then up to here on the I-25.

At least he can stop at Shooters for lunch....

My Son Has Started His CALEXIT

 So SLW and I have been cleaning things up and getting ready. 

His trailer is loaded, and he'll be "Leaving L.A." momentarily. He's taking the Southern Route, as he got a bit nervous when I was blasting through the mountains with him, trailer in tow at 75MPH, when he came out here with me back when SLW and I moved here.

Hard to believe we've been here close to four years now.

I told to make sure he stops on the corner in Winslow, Arizona, and I'll tell him to send up a flare as he goes through Flagstaff. Maybe LL or some others will see it.

Didn't get back on the TEAC, as I had several more pressing things to do, like sweeping, mopping, picking things up, some more PT, and a list of new exercises for my left shoulder.

Gettin' old sucks!

We'll keep you posted.

Via Con Dios, my son....

Possible Explanation of "Too Fast" Recordings.

 OK, so after pouring over the Service Manual for the TEAC, I see no mention of any "Speed Adjust", which makes sense as all three of the motors are AC motors, meaning they're pretty much "locked" to the frequency of the incoming AC power.

Everything turns freely, and recordings I made using the Pioneer on FM for a source sound great. The recordings I made at 3-3/4ips sound good, while the ones made at 7-1/2ips sound even better.

I'm shopping now for a "Test Tape", aka "Calibration Tape", which will confirm that the recorder is running at the correct speed. Until that gets here, I'm going to run 10 seconds of tape, and measure the length. Should be pretty close to 45" of tape at 3-3/4ips, and 90" of tape at 7-1/2ips. I know this isn't "exact", but it'll be a pretty good ballpark guesstimate, and will have to do until I can get a real test tape.

BUT.....what could have caused the deck to run slower than "normal" when these old recordings were made?

The only explanation I have is that the AC power at U-Tapao where these tapes were made was 50Hz power, and not 60Hz power. 220V/50Hz could be stepped-down to 110V/50Hz, making the Voltage OK, but not the frequency. Since I know little to nothing about the base infrastructure back then, or where they got their AC power from, this is a "First Order SWAG", and I might be 100% wrong.

Anybody know anything about the AC power used in SEA back then? I'm pretty sure if the were running on US generators they'd have 220/110 60Hz, but what if the "Host Country" supplied the power? The wikkipedia entry indicates that Thailand currently (no pun) uses 50Hz power, so I may have found the "problem" with the tapes running fast.

"First Light" with TEAC A-4010SU

 And the verdict is.....It's running too fast. I'll have to go into the Service Manual and see how to check and adjust the speed. I tried several of the recorded tapes "The Colonel" gave me, including the Bob Hope tape after I was sure the deck wouldn't eat it, and they sound like Alvin and the Chipmunks. I recorded some songs from a local FM station using  the Pioneer receiver at both 3-3/4ips and 7-1/2ips, and they play back great, so some components or adjustments have shifted between when the tapes were made on this deck and now.

You can tell it's Bob Hope talking, but the tape is sped up to the point that it's not really listenable.

I looked up some of the artists whose names are listed on the tapes, and they're mostly from the 1930's and 40's, swing, and big-band stuff. And a couple of the artists had notes on their bios that all their master recordings  were destroyed in the 2008 Universal Studios Fire. I don't think these tapes are "valuable", but I'll ask around on some of the vintage tape forums.

So the radio and speakers work fine, and I can play records on the turntable without crazy feedback, and if I make my own recordings, I can play them back fine, but to me, the deck still has a problem.

Hmmmm....Another Training Flight?

 Saw this guy orbiting around today.

The tail number indicates it's an RC-135 "Rivet Joint" aircraft.

Getting in some practice, I guess.....

Big Rain!

 The barometer went way up, and the temp dropped about 25*, and it's pouring here. NWS has issued a Severe Thunderstorm Alert, and Flash Flood Warnings. Per the NWS weather radio, over 1-1/2" of rain have fallen, and up to two inches more could happen.

The dark red areas are the burn areas from last summer, and the yellow area is the storm warning area.

The weather map was updating when I did the screenshot, so there's a bit of missing data to the West.

Here's one a few minutes later.

As "usual" (or so I've been told....) out here, the worst of it is mostly East of I-25, and there were reports of "Quarter-Sized" hail from up around Wellington.

Yeah, slow "news day" here. Had to completely strip the rack the stereo is going to reside in as it was blocking the outlet I want to use, and I wasn't going to move it with that much weight on it. A side result is I'm also going to anchor the rack to the wall. Even with the heaviest items on the bottom, I don't want to find myself needing a hand-hold to get up off the floor, and accidentally grabbing the rack. A couple of hundred pounds of vintage equipment landing on me would not be pleasant.

TEAC A-4010SU Wrap-Up

 All clean and shiny again!

I cleaned the wood case today, and applied/rubbed in a generous amount of "Old English Dark Wood Scratch Cover", and let it soak in while I replaced the tape counter drive belt, cleaned the level controls on the record electronics, and did a few other things..

After it had soaked in for a couple of hours, I buffed it with a microfiber towel. It had  looked pretty shabby after cleaning 60 years of "stuff" off, but the wood oil really brought it back.

I pulled the top cover from the receiver as I had to replace the dial lights, and was going to give it the same treatment, BUT.....it's a particle board cabinet with a vinyl "wood grain" applique. Pretty much what Mom called "Contact Paper", and used on her shelves. I did mange to repair some areas where the wood grain applique had lifted, and gave it a good cleaning, so it looks much better than before. Since the Pioneer SX-780 was their "Loss Leader", I guess the cabinet was where they saved a few bucks.

So now I have to move the TEAC downstairs, and connect it all together. Then I can find out what's on that "Bob Hope USO Show" tape that I found in the box they gave me.

Interesting Flight Path

 Looks like they may be doing mapping or photo flights.

Most people don't realize the the "Satellite" imagery used in Google Maps is actually from USGS photo flights.

This is the first time I've seen one using my little ADS-B receiver and display program.
