W7YV Ham Radio

One of the projects on my Never Ending Project List is to build a 10 GHz Microwave Station (3 cm band). A logical first step, I think, is to build a 3 cm beacon. There is a great deal of information on that topic. In particular, KA7OEI has done lots of work and published his findings . (TNX CLINT). Thinking about that led me to the discovery that the site websdr.org has nearly a dozen SDRs that listen to the 3 cm band. So, I thought I would make a list here and share it. SDRs Listening To The 3 cm Band http://websdr.suws.org.uk/   One beacon found sending FSCW (Frequency-Shifted CW) and an unidentified digital mode having four discrete frequencies. http://maxiplaya.dyndns.org:8901/  Nice CW beacon on 10368929.65 sending chirpy code. http://ea1rj.cloudns.cc:8888/  No beacons detected. http://erc-websdr.esa.int/  No beacons detected. http://websdr.fvzr.ch:8901/  Beacon at 10368086.74 sending unidentified digital mode. No CW heard. ...

Woo Hoo! A new toy joins the shack's boat anchor collection. I used this device when I worked at Edo Western many years ago. See this page for a complete description.

I have an interest in building an ELF receiver that can hear whistlers. Here is a YouTube video of what they sound like: And, here is a link explaining what they are:  https://en.wikipedia.org/wiki/Whistler_(radio) One problem is that, to hear the signals in the range of 0 Hz to 20 KHz, it is best to get well away from the urban environment with all the 60 Hz power line noise. So, I thought one could place the receiver on a mountain top. It could be powered with solar cells and beam the data back on a telemetry link (UHF) to a receiver here in the valley. From there, the data could be made available as a feed to the MESH network sites. More later....
