SDRplay Receiver

Since I won a $100 gift certificate for HRO, I decided to use it on a little gadget I've had my eye on for quite some time now.

It's called an "SDRplay", and is a little software defined radio receiver,

I've experimented a bunch with the USB "dongle" receivers, and had a HackRF1 for a while. The problem with the dongles and the HackRF receivers is that they only use 8-bit analog to digital converters, resulting in a pretty severely limited amount of dynamic range, especially if you live in an "RF Alley" like the metro L.A. area.

Strong signals on far removed frequencies "break through", and I had to turn down the RF gain and the IF gain in the software to get decent performance out of them.

Running them with my 144 MHz "eggbeater" antenna and an SSB Electronic preamp, which includes a helical filter, made them perform much better for 2 Meter Ham Radio work, and 137 MHz APT weather satellites.

The SDRplay uses 12-bit ADC's, so it should be quite a bit better.

I haven't tried the SDR play on my Windows PC yet, but it looks like it's going to take some fiddling around to get it to work on my Linux PC.

It gets properly detected when I plug it in to the USB port, but Gqrx and Linrad both barf when I try and make it receive.

And yes, I followed the instructions to the letter from the SDRplay website about installing the drivers and API.

Just have to do some more digging around, I guess....

Fracking Computers.........

No, this isn't about oil extraction.....

The other night, OpenSUSE installed some updates on this PC that broke the audio. This is rather unusual with OpenSUSE, because they usually run their "A Game", and I haven't suffered a "bad" update in years.

Of course it just might have something to do with the fact that I have various audio things things installed in a rather "unstock" configuration because the OEM setup doesn't include all the various codecs and other stuff I use for messing around with SDR things.

SO....since it's been a couple of years since I built this PC, I decided to upgrade to the newest version of OpenSUSE.

Off I went to Best Buy to grab a couple of new hard disks, as anytime I upgrade, I install new drives. That way I have my previous OS and all my applications available so I can extract bits and pieces of things, and all my documents, pix, and other stuff is untouched by the upgrade to the new OS.

Tore the PC apart, dragged it outside and blew all the dust bunnies out of it, installed the new drives, dragged it back in here, nd proceeded to install OpenSUSE "Leap" 42.1 on it.

I also took this time to install new video cables between the PC, KVM switch, and monitor. Sometime last year my KVM switch took a dump, and I replaced it with a new one of the identical type from Monoprice.

It caused nothing but grief with the video switching, so I just ran the video cable from the monitor directly to the PC, dragged another monitor in here to use with the Windoze PC, and used the KVM switch for just the keyboard and mouse.

Last night I installed new, very high quality "Dual Link" DVI cables in place of the DVI cables that came with the KVM switch. All seemed good until after the installation of the new OS, when I started to have numerous problems with the keyboard not responding, the mouse not responding, and the video doing strange things.

The KVM switch uses a USB connection between the PC and the switch to handle the keyboard and mouse, so I moved that cable to a USB 3.0 port on the back of the PC, and all seemed well.

This morning the weirdness started again, so I decided to just reinstall the OS, carefully picking only software that I needed, and leaving out some of the other stuff for now. Not quite a "Bare Bones" install, but not the "Kitchen Sink" install I usually do, either.

It seems more stable now, but has hung twice when I open the Dolphin File Manager (Windows Explorer for you non-linux folks).

The next thing to do is to TURN OFF all the fancy schmancy eye candy bullshit that everybody includes these days, like window transparency, window fades when switching tasks, the bouncing mouse cursor that shows you when it's busy, and all the other useless, annoying shit that's turned on by default to show you just how clever and creative the programmers are.

And I'll go to NVIDIA and grab the latest driver "blob" for this fairly high-end video card rather than use the Open Source video driver that's included. A lot of people in the Open Source community bad mouth NVIDIA for not releasing their source code so the community can do a "proper" Open Source driver, but that doesnt bother me.

I just want my system TO WORK, and if that means using a closed-source driver module, tough shit. At least I'm assured that the driver works, works properly, and won't get all weird on me during an upgrade.

And if this doesn't clear up the lingering issues I'm having, then I'll try running the video directly from the card output to the monitor again, and see if that makes it fully stable.

Oh, well....off to my Doctor's appointment, which is why I'm not on the Iowa today.....

Email From a Buddy

A gun is like a parachute.
If you need one, and don't have one,
you'll probably never need one again."

The definition of the word Conundrum is:
Something that is puzzling or confusing.

Here are six Conundrums of socialism in the United States of America:

1. America is capitalist and greedy -
yet half of the population is subsidized.

2. Half of the population is subsidized - yet they think they are victims.

3. They think they are victims - yet their representatives run the
government.

4. Their representatives run the government - yet the poor keep getting
poorer.

5. The poor keep getting poorer -
yet they have things that people in other countries only dream about.

6. They have things that people in other countries only dream about - yet
they want America to be more like those other countries.

Think about it!
And that, my friends, pretty much sums
up the USA in the 21st Century.
Makes you wonder who is doing the math.

These three, short sentences tell you a lot about the direction of our
current government and cultural environment:

1. We are advised to NOT judge ALL Muslims by the actions of a few lunatics,
but we are encouraged to judge ALL gun owners by the actions of a few
lunatics.

Funny how that works. And here's another one worth considering.

2. Seems we constantly hear about how Social Security is going to run out of
money. But we never hear about welfare or food stamps running out of money!
What's interesting is the first group "worked for" their money, but the
second didn't.

Think about it.....and Last but not least :

3. Why are we cutting benefits for our veterans, no pay raises for our
military and cutting our army to a level lower than before WWII, but we are
not stopping the payments or benefits to illegal aliens.

Am I the only one missing something?

are doomed to live under the rule of fools." - Plato

First Flight Scheduled for B-29 "Doc"

I'm one of "Doc's Friends" in that I've given them what support I can comfortably afford.

WELL.....Doc is scheduled to take to the air next Sunday, July 17th!

Here's the press release I just received:


First Flight Scheduled for B-29 Doc
WICHITA, Kan., July 8, 2016 – Doc’s Friends, the group managing the restoration of the B-29 known as Doc, announced today the historic B-29 will make its return to flight Sunday, July 17. The restored Boeing B-29 Superfortress will take off from the non-joint-use runway at McConnell Air Force Base, adjacent to where the restoration team has spent the last 16 years restoring the warbird.
“Hundreds of volunteers have spent thousands of hours working to restore this national treasure,” said Jim Murphy, Doc’s Friends Restoration Program Manager. “After 16 years of hard work, sweat, tears and tireless attention to detail, we are ready fly.”
Doc’s flight crew expects first flight to be an early morning event on July 17 due to anticipated hot weather. First flight is also dependent upon weather conditions in Wichita and plans could change with little or no advanced notice.
Due to security restrictions at the active air force base, as well as security access at Doc’s home at Air Capital Flight Line, runway and ramp access will be limited.
The public, however, will have multiple locations from which they can view Doc’s first flight and landing. Specific details of those public watch areas and first flight timelines will be released soon.
The public is encouraged to subscribe online at http://www.b-29doc.com/signup/ to receive information regarding the public viewing locations as soon as the information is released. The information will be provided to the media for public disclosure via news releases.
About Doc’s Friends
Doc’s Friends is a 501c3 non-profit board managing the restoration of the Boeing B-29 Superfortress known as Doc. The group was formed in 2013 and is led by retired Spirit AeroSystems CEO Jeff Turner along with other Wichita business leaders; Charlie Chandler, Jack Pelton, Steve Clark, Lynn Nichols, Brad Gorsuch, Ron Ryan, Tim Buchanan, Jeff Peier, Esq., and Tom Bertels. Doc’s Friends is committed to returning this World War II warbird to the air to honor previous generations, educate current and future generations and connect the world to the rich heritage of aviation.



I'll be keeping my fingers crossed that all goes well. Be nice if Doc and Fifi can get together sometime soon....

AES Closing After 59 Years

Well, this has all the Ham Radio tongues wagging.

Amateur Electronic Supply, headquarted in Milwaukee, Wisconsin, is going out of business at the end of July.

I bought tons of stuff from them over the years, and they were Good People to deal with.

Sad to see a brick and mortar Ham Radio store close, but profit margins on Ham gear are very low, and Hams are notoriously cheap, so running a major chain of Ham Radio stores is a headache I wouldn't want to have.

I'll miss them, they were truly a fixture in the Ham radio world.....

Here's the story, courtesy of the ARRL website:

Amateur Electronic Supply (AES) will close its doors at the end of July after 59 years in business. No reason has been given for the decision to close the business. AES has been a premier player among Amateur Radio equipment retailers for decades, as well as a major presence at Dayton Hamvention® and other events. Various media outlets were informed of the closing in a brief e-mail message on July 6, but word of the closing has not yet appeared on the retailer’s website or Facebook page.
“It’s with great sadness that I have to tell you that Amateur Electronic Supply (AES) will cease operations at the end of this month,” AES National Sales Manager Tom Pachner, W9TJP, said in an e-mail. An employee at the Milwaukee headquarters store, who did not wish to be identified, confirmed that the message was legitimate. It’s believed that the AES staff was notified before the July 4th holiday weekend. In addition to the Milwaukee store, AES operates outlets in Cleveland (Wickliffe), Las Vegas, and Orlando.
Fond-du-Lac, Wisconsin, native Terry Sterman, W9DIA (SK), founded AES in 1957 when he was just 18, after getting into the radio-TV business by working in his father’s TV and electronics parts store. On January 1, 1998, ownership of AES shifted to Amateur Electronic Supply LLC, headed by Phil Majerus, a prominent Wisconsin businessman. Sterman died the following year at the age of 60, after a period of ill health.
For many years, the public face of AES was its Executive Vice President Ray Grenier, K9KHW, who oversaw marketing and advertising for the retailer from 1964 until his retirement in 2013. Grenier nearly singlehandedly produced the famous AES catalog, as well as magazine ads. For about 20 years, he also organized the well-received AES Superfest, a promotional effort begun in 1995 that grew into a hamfest. In April, the AES Superfest hosted the 2016 ARRL Wisconsin Section Convention.
Many radio amateurs reacted to the news on various online forums, expressing surprise, sadness, and dismay, and saying they would miss AES. A few reminisced about having bought their first radios from AES.

A Song For the FUSA







I'm not really a betting person, but I'd be willing to bet there's going to be massiver voter fraud in November.

And I mean breathtaking.

It'll be so bad, and so blatant, that Richard J. Daley would blush.....

Hillary Gets a Pass.....

I'm shocked, I tell you...just shocked.

OK, folks...it's official now. The Rule of Law is now DEAD and BURIED in the Former United States of America.

The FBI said they couldn't find "intent" to violate the laws regarding the handling of classified information.

Well, Bubba...if you or I did the same thing, just the act of setting up our own private server, which is itself a CLEAR violation of the law, would have been plenty of "intent" to violate the law and gotten our sorry asses sent to a Federal-Pound-You-In-The-Ass prison.

Stick a fork in the USA, man.....it's DONE.....

Happy Independanve Day!

I'll be headed out to the Iowa in a few minutes to finish installing the LP-PAN panadaptor I got for NI6BB.



The audio cables that transport the "I" and "Q" signals from the box to the M-Audio sound card were a bit too short, and too stiff, and the BNC cable that transports the IF signal from the TS-850 to the box had BNC connectors on both ends, while the radio uses an RCA connector for the IF out.

SO, after I got home from the ship yesterday, I made some new cables that should work much better.

Don't eat too much today, and remember what the holiday is all about.

Like I have to remind my readers about what it means.....

Poor Puppy!

Poor Little Miss Pebbles decided she does NOT like fireworks this year.

She was fine last year, but now every time something goes BOOM, she runs to the door or a window to see what it was.

She's not scared, more annoyed and protective.

Be a "TWO Benadryl" day tomorrow.....

Battleship Iowa Interior Panoramic Views

In case you haven't been to the site that hosts these, or haven't been lately, there are a LOT of areas that have now been photographed, and added to the site.

One of the recent improvements to the museum area on the second deck has been the installation of some 60" (I think) monitors that have interactive views of all these.

There's a mouse, or track ball, or other pointing device, and the public can select the area of the ship that they want to see, and "explore" it in a Virtual Reality kind of way.

These are almost all areas that are Off Limits to the public, and I haven't even been to most of them.

The fact is, at my age I don't think climbing up to the "O-12 Level" is much fun, and going all the way down into the bowels of the ship isn't much fun, either, so I'm grateful that the photographer has been allowed access to the ares, and done such a knock-out job in documenting them.

I haven't been down to the museum area in a while, so not having seen the new exhibits, I'm fuzzy on the details, but knowing the quality of work that our crew does, I'm sure it's quite impressive.

Enjoy!

WTF...No More Silver Plated BNC Male Connectors for RG-8X???

DUH....

Just looked at all my usual suppliers, and these seem to be NLA.

There are plenty available for RG-58/58 foam, but none for "Cable Group X", which also includes LMR-240.

I could use RG-58 for this little project, but in my humble experience, RG-8X stands up better to rough handling.

It's just to make some 3~5 foot jumpers for 3~30MHz, so the loss of the cable is irrelevant, but as I noted, 8X stands up to rough handling better than 58 does.

sigh.....looks like I'll have to use 58, which means a trip out to the garage to see if I can dig up the roll of RG-58 I bought years ago.

I knew I should have stocked up on these the last time I ordered them.

Good quality connectors and adapters to an "RF Guy" are like ammo to a gunney....it's hard to have "too much/too many"!
