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.
