So, part of my incentive on working on my WSPR beacon was one of my coworkers decided to try to do some operating from the local Emeryville Marina, and I thought it might be nice to use the opportunity to try to pack up my WSPR setup and see if I could get some spots […]

I’ve been interested in low power beacon transmitters for a long time.  If you’ve followed my blog, you’ve probably read about my experiments with WSPR and QRSS operation.  Most of those took place on 30m using my FT817 transmitter, sometimes with software that I wrote myself.  But I’ve long thought that I should homebrew a […]

Okay, this is pretty basic stuff really, but it’s part of my trip toward additional homebrewing, and it might be of some vague interest, so here we go. If anyone spots anything horribly wrong here, please feel free to help me learn by leaving me a comment here. Before Thanksgiving, I was having quite a […]

While I am on the antenna kick, Howard, G6LVB mentioned his page on putting two cheap yagis on the same boom. Very, very nice. 10db of gain for a reasonably small antenna, and RHCP to boot. Homebrew Satellite Antenna.

Okay, I hadn’t been doing any WSPR beacon operations since before Thanksgiving (which was also before my new callsign) and I was kind of bored today, so I dug out my power supply, tuner and interface and set my computer beaconing again on 30m. It’s a combination beacon: using WSPR above 10.140100, and a visual […]
