The Breezeshooters’ Hamfest 2023 - Butler, PA.

Sunday, June 18, 2023 at 14:52:43

This year’s show was the first in several years after being closed because….reasons. It returned to the Butler Farm Show grounds this year, which is another fairgrounds-type venue located near Butler, PA. I didn’t get quite as many pictures as I wanted, but there was quite a bit of good stuff there, and we spent the better part of the morning browsing before heading to the Monroe Hotel Restaurant for lunch.

The day itself was supposed to be decent, but it was surrounded by rainy days. We weren’t sure what to expect, but it turned out to be warm, sunny, and not too hot. A perfect day for going out and wandering around.

Unfortunately, as we were walking in, there was some commotion - seems that someone had walked off with the money pouch for one of the vendors. Whomever did this is absolute shite and deserves whatever they get. Even at events like this, there are those who shouldn’t be in society.

First thing I saw was a table run by an older gentleman who looked as if he was cleaning out space. The EICO audio test amp was only a few bucks and went home with me. It’s going to be the subject of a later post.

A couple of interesting old tube testers showed up, including this TV-7B/U. It looked used, but in decent shape. Out of my price range, of course.

A vendor had some solar panels and an assortment of controllers in a box. Your choice, mix n match.

I can’t see this being useful for anything other than a costume prop…

breeze23-mp3-wereboar.jpg

A neat old Hickok signal generator. I can’t use this, but the design is cool and would look good as a movie prop.

The club had a bunch of stuff they were selling off to raise money for the club. They had these scope carts that were super cheap. These things are super-heavy-duty and were a steal at the price.

They also had this interesting RCA television for $5. Someone got a steal on this guy.

Last thing of the day was this tube tester and audio meter. I wanted to take both, but the roller chart was missing from the tester and the audio analyzer was full of tubes and wood shavings. I left both of them for someone else.

All in all, it was a good show, and there was a lot of things to see. Next week, I’ll be posting about the things that I brought home, and later, a diagnosis of the audio test amp.

Next show is Columbus in August. See you there!

Dayton 2023: Stuff I drug home.

Saturday, June 3, 2023 at 17:38:07

I made good on my promise to not drag home too much junk this year, but a few boat anchors did manage to make their way in my car. Both of them had an immediate use, but the one that was going to go in to the rack didn’t work. Not a big deal, but still…it gives me a chance to re-engineer some stuff. The rest of the items were parts for later use, whenever the need arises.

dayton23-stuff-wereboar.jpg

Just some random bits I picked up. An old LED display (made in the USA!) from Rat Shack, and a 1971 Allied/Radio Shack catalog. The catalog is fascinating, the prices that some of the things cost was incredible, and it’s interesting seeing some of the Shack’s staples like the Weather Cube. It’s fun to look through it and see things I wish I could still buy.

dayton23-jimpak-wereboar.jpg

A vendor was selling older Jim-Pak parts, as well as a handful of things from other vendors. Some were $1 per, others were 2 or 4 per $1. I picked a selection of parts, as well as some of those oddball fuses old meters used for their current sections.

dayton23-audiodevice-wereboar.jpg

This is a unit that was meant to monitor the audio feeds in a studio. At it’s heart, it’s two “channels” with a center channel. Unfortunately, it didn’t work. Examination reveals a lot of white corrosion on the input board, and it looks like some water was spilled and lay on the board for a long period of time. That’s not really a big deal, I’m thinking a couple of LM386 ICs can fix this guy right up. I’m not interested in studio accuracy, I want something for my rack that I can connect to the plugboard for audio testing.

2025: it’s going to auction at a local club.

According to the vendor, this works. Well…it didn’t. Mostly. I picked it up for parts since many of these are being torn down for the displays so they can become clocks. :( The device itself had a hard life, evidenced by the replacement screws in the bottom and the considerable cosmetic damage to the unit itself. It had all of it’s feet and bail, so that’s quite nice.

An examination on the inside revealed many repairs, some boards that had left their slots, and a missing fuse. Bringing the device up on power revealed that it indeed did not work, the master clock was not present so the device wouldn’t sample. One of the tubes was also partially bad, but it had the incredibly rare polarity indicating tube, probably worth the price of the device itself.

While cleaning the card edges I found that the clock card had a transistor leg lifted, so someone was troubleshooting the device when it was put aside. As this was supposed to be a parts unit, I’m not sure how far I want to go fixing it - if at all - but it will be the subject of a future post detailing the examination.

dayton23-monitoradio-wereboar.jpg

This is one of Radio Shack’s oddball devices from the CB radio era. It’s a crystal-controlled device that listens to Channel 9, which was commonly used as the emergency channel It was designed for antenna passthrough, and has it’s own speaker. If I can find a schematic for this, I may see if I can re-tune it to Channel 19, since there’s still a little activity there.

dayton23-cable-wereboar.jpg

A friend of mine said he wanted a 2-pin cable for a battery box project he made. Said he needed an extension, so I found this. It’s not going to get warm anytime soon.

dayton23-buckle-wereboar.jpg

This was a CB-era piece in the bins with the Jim-Pack parts. I don’t know why I got this other than it’s funny. Rip-off characters, anyone?

The slim haul wasn’t because I didn’t see things I wanted. I did. A lot of it. There were a couple of pieces that I saw that I wanted to bring home, but didn’t have a need for - a WWV receiver and some other devices among them. I figured if they were there Sunday, I’d bargain, but they weren’t. That’s me being told that I don’t need them, leave them where you found them.

(But you know very well if I see that receiver again I may pick it up because I’m being told it’s still here so you know you want it!)

Overall, I think I got some good stuff. The meter may make an interesting project, should I decide to repair it, but I think it’s just parts with a good plug-in for my other devices.

Next show is Butler, PA, and then nothing for a few month. Stay tuned for some show posts from that one, and some detail posts on a few of the devices I’ve picked up over the last year.

The Breezeshooter’s Hamfest - June 4th 2023

Tuesday, May 30, 2023 at 05:46:15

This is generally a smaller show, but it’s one where good deals can be had - some of the “Dayton” items show up without the “Dayton” prices! I’ve always brought home a decently priced trinket or two from this one.

This year, they return to the Butler Farm Show grounds, with a single day of show on Sunday. See you there!

The Dayton Hamvention 2023

Wednesday, May 24, 2023 at 08:03:27

We all had a good time at Dayton this year. Weather was very cooperative, with temps in the 80s and most of the rain being confined to Friday evening and early Saturday morning. (It wouldn’t be Dayton without Rain, Snow, Tornadoes, or 100F heat, now would it?)

As usual, there was a lot of good stuff to be seen and had, and I limited myself to things I thought I could immediately use - for the most part. The flea market was full, and the exhibit halls were packed as usual. So without further ado, here are my pictures of the event.

The Dayton Hamvention 2023 has come and gone.

Monday, May 22, 2023 at 08:29:34

This year, I made it two days instead of just one - perhaps next year I’ll try for all three. There was plenty of stuff to be had, and I limited myself to some parts units and some odds ‘n ends. I think the total damage this year was under $200, and that included food and drinks for myself and my fellow show-goer.

I’m in the process of cleaning up the pictures I took, and will be posting those and my haul over the next few weeks. Stay tuned!

The TUSCO Amateur Radio Club 2023 Show - Junk I Took Home.

Tuesday, May 2, 2023 at 07:50:49

I tried to limit myself to Small Things this year, and not drag home any projects. I almost succeeded!

The meters are of particular note, one was an old, old, old unit with a telephone test jack on it. I occasionally have need to test single-line analog jacks, so I offered the guy $10 for it and he took it. The other meter, an Ohio-made Triplett, was a beast of a unit costing $200 when new in 1992. It’s loaded with functions, and has internal relays to isolate and switch inputs. Quite unusual and cool.

The other items were simply parts, unusual test equipment, or books. Not pictured are some RCA tube manuals I picked up for $5 each. You’ve seen those before.

The ZM-11/U - this is an interesting piece of equipment. It’s a fairly precise bridge for checking capacitors and inductors, and uses an eye tube as an aid to the relative quality of the device under test. It’s in pretty good shape physically, a few dents and dings and one broken bail on a clip.

Electrically, the vendor said that it worked (and it all lights up,) but that the internal 1Khz source was dead. Feed it an external precision source and it’s fine. I’m planning on digging into this device at some point, it needs a cord and some minor cleanup. I’ve already removed the line cord as it was in bad shape. When I get to it, that will be it’s own post.

Next up is Dayton on the 19th of May, but until then, enjoy the pictures!

The TUSCO Amateur Radio Club 2023 Show

Tuesday, May 2, 2023 at 07:12:39

This was the first time I’ve attended this show. I wasn’t sure what to expect, but it turned out to be pretty good for being such a small show. I spent about an hour and a half wandering the two halls, looking at thing and re-checking them to make sure they didn’t want to come home with me. I left several things behind but brought home several more.

This show was at the Tuscarawas County Fairgrounds, and occupied one of the commercial buildings. There was mention of a “trunkfest,” so I suspect that there may have been some outside stuff had it not been a rainy day. Overall, however, it was a good way to spend a Saturday morning. I’ll probably go next year, time permitting, since it’s so close.

The 2023 Dayton Hamvention is almost upon us!

My haul from the Cuyahoga Falls Hamfest.

Friday, April 28, 2023 at 07:44:36

As usual, there was a lot of good stuff to be seen at the show. I had to force myself to not bring it all home because a lot of it isn’t useful (to me) past a “Wow, that’s neat!”

cfarc2023-relays-wereboar.jpg

Boxes of relays from the “Pay what you want table.” This is all donations for the club, and was the estate of a now silent key.

cfarc2023-modems-wereboar.jpg

Hayes 56k modems that were part of a BBS. Yeah, I don’t know why except that they’re a matched pair.

cfarc2023-gateway-wereboar.jpg

An interesting Ethernet to Serial gateway. Vendor said it was from a friend who was doing some odd project. It was free, with the caveat that it’s a project case if it doesn’t work.

cfarc2023-nanners-wereboar.jpg

Jacks from Rat Shack of the past. Nothing more to say about this.

cfarc2023-adventureland-wereboar.jpg

Adventureland is the game that’s credited as defining the Interactive Fiction genre. While the original release was for the TRS-80, the VIC-20 version wasn’t far behind. I don’t have a VIC, so this cartridge is more as a piece of computer history than as a useful item.

cfarc2023-counter-wereboar.jpg

Of note here is this Regency counter. This device is kind of unusual for something Regency produced. It’s a fairly competent piece of test equipment with a crystal oven and a known ppm deviation. Apparently, it was designed for FCC compliance checks (at the time of manufacture.) It works, but needs an alignment. If I can find some service data, that will be it’s own post.

I kind of wish I’d got that phase corrector device, I found out later that it went for $5 - that’s a steal and a shame, but I have no use for it.

Next post(s) will be the TUSCO Hamfest. That one was small, but excellent. Stay tuned!
