Practicing with the Begali

Got my Begali Camelback straight key wired up with a standard 3.5mm TRS cable, and made up an adapter cable to connect it to the Heathkit HD-10 keyer.

I’ve been really enjoying practicing Morse code with the Camelback. The solid, weighty base gives it a super stable feel and a nice satisfying thunk-y sound as opposed to the more clack-y sound from the J-38 key. I’m sure if I mounted the J-38 on a more solid base, it might also have a nice thunk-y-er sound. I’ll have to look around for something heavy to attach the J-38 to now.

The Camelback is hefty enough that it doesn’t move around while I’m keying. The Vibroplex bug is also pretty hefty, but will slide around a bit while I’m using it. I probably need to replace the feet or put some grippy pads on them to keep it from sliding around.

Connecting the straight key

After going through the manual for the HD-10, I learned that the terminals on the rear of the HD-10 could be used to attach a key. So off to the garage I went to put some terminal connectors on some wires to use to hook up the J-38 key to the HD-10.

It took a couple of tries before I figured out where the wires were supposed to go on the J-38. There are lots of pictures of J-38 keys on the internet, but not too many that show how the wires are supposed to be attached (the terminals are the two on the inside).

With everything connected, tapping the key made the keyer make noises and I managed to make some Morse Code sounding noises with the key. Now they can sit on the desk next to me so that I can practice tapping out Morse Code whenever I feel like.

I still need to take the key off the base and clean it up a bit, and then make up a cable that I can use to plug the J-38 into the radio with. Also thinking about seeing if I can find a nice block of wood to attach the J-38 key to for a more solid base and to elevate the key a bit.

Scanning manuals

Now that I’ve finally got my scanner to work under Fedora, I thought I’d use the opportunity to scan the manuals I got with the Heathkit IG-102 signal generator I picked up a while ago. I was also lucky enough to find an assembly manual on eBay for the HD-10 keyer I picked up at Hamcation so I scanned that as well and converted them both to PDF files.

There’s another manual for the IG-102 that’s quite a bit larger (168 pages) that will take me a while to scan and convert, but I’ll get that done eventually.

Hamcation acquisitions

Day 2 at Orlando Hamcation was spent looking for antenna things and CW keys. Lots more people at Hamcation today than there were yesterday, which was expected. After wandering around to the different tables in the swaps area and wandering around the bone yard, I had a better idea of what I wanted to get.

Picked up some stranded copper wire, coax and ladder line for antenna projects, and then it was out to the swaps building.

First acquisition was this J-38 straight key. It’s a little dusty, the flat knob is a bit chipped and the shorting switch is missing, but it had the best action of the other J-38 keys the guy was selling. It needs some cleaning, but I’m looking forward to learning more about this style of key and wiring up to play with.

A breadboard, some 7 segment LED modules and some kind of metering panel that I’ll use for parts.

The next acquisition was this Heathkit HD-10 keyer. The guy selling it had it in his shack gathering dust for years and wasn’t getting too many bites at the price he was initially looking for, so I managed to pick it up for a great price. Plugged it in and it works pretty well.

Toward the end of my bone yard wanderings I spotted these variable plate capacitors on the table and scored them for $2. Some of them are a bit oxidized and need a bit of TLC, but I think I’ll be able to put them to work doing something.
