My Peaberry Puts out Power --- Sort Of

I've been working on this Peaberry kit for longer than a year, now. I've been tweeting updates and stuff because there's not a lot to tell. It's taken so long because it's, by far, the most complicated tangible thing I've ever built. I've written programs that are more complicated (it's what I do for a living, after all, and people never seem to want simple programs) but those aren't tangible. Of course, I have run into problems during the construction. It's part of the nature of the beast.

What I've Been Up To Lately

It's been a while since I've put anything here, but I've been busy the whole time.

I received a Peaberry SDR V2.0 kit as a gift, and I've been assembling it. I've gotten to the point where the entire receiver is built and works, and I'm working on the transmitter. I'm building the 20, 30, 40, and 60 meter version of it, if anyone cares. At some point, I'll have to find a nice Linux SDR application I can use it with. Up to now, I've just be using the recommended Windows application because it's recommended. I want to control the uncertainties in any project I do.

How to Make an SDR CW Receiver

I've been working on an SDR (Software Defined Radio) receiver that I can control via computer so I can use my TV receiver dongle to work linear transponder satellites. It hasn't work or, rather, has kind of worked strangely so last night I took it apart, metaphorically, and experimented with locally-generated signals so I could try to figure out what was going on. Having identified the errors, corrected those errors, and tested the correction, I can now explain how to make one of those things that works. The receiver part, anyway.

Adventures in Satellite SDR

While I'm waiting for new boards to come in for the Arduino-based memory keyer and while I'm waiting for NC4L to get my money order so he can ship my FT-102 back, I'm working on getting back on the satellites. I've decided to try my hand at the linear-transponder satellites. I've watched guys like Andy (W5ACM) operate linear satellites with nothing more than an FT-847 and some well-practiced skills, but I don't have any FT-847 equivalent, and the all-mode radio that I do have is computer-controllable so I can run computer-controlled.
