  • How many WSPR decoders can be run without affecting performance?

    I would suggest you use Rob's 2nd computer scheme. It was kiwiwspr.sh but now wsprdaemon.sh. It will service all kiwi channels without any issues.

  • Noise at roughly 60 KHz intervals

    I note that the high-quality shielded Cat cables have the drain wire tack soldered to the metal clip at the plug. Sadly, I have also found that "professional" installers often do not even deal with the drain wire on installations in businesses.

    If you do a full freq look at the Kiwi WF you can often see the chirp sweep go by. I'd like to be able to pick a chirp TX site by name name, Millstone Hill for example, and knowing it's start time, be abe to ID that sweep that goes by. The highest freq seen would indicate the MUF for it at the Kiwi RX site.
