Starting to publish the keyer project.

A fully populated keyer dongle

Lots of things have happened with the keyer. I bought rotary encoders and had boards made and populated one and it works like a champ. Only one small error on the board, and it's in the silkscreen so I'm going to ignore it, although you can see it in the photo above. So, if you have an interest, how can you get your own keyer?

Well, start at OSHPark and get yourself some of the boards:

A "Magic Band" Antenna and More Keyer Progress

My six-meter quadrifilar helix antenna

Well, I finally went and did it. I built the 6-meter quadrifilar helix I've been talking about for years. Okay, it's not quite done, I'm waiting for a decent pair of wire strippers to arrive, but a week ago I took a four-inch PVC pipe, some 3/8 inch dowels, some Romex, and adhesive and fabricated a QFH antenna. I used a short Python program I wrote to determine the dimensions and, well, I did it wrong. The short wire in what I built should be the long wire at the operating frequency, so the whole thing is too long for the 52 MHz design frequency.

Keyer Project Update - Almost Public

Well, I've been working on the memory keyer and it now can record and play back memories programmed through the keyboard. I can send a serial number that gets updated automatically, and I've fixed the odd bit here and there. I've confirmed it compiles through the IDE on Windows, although I'm still stymied by the IDE under Linux. I also tested to see if it really would key the FT-102. It does.
