ISS Repeater

I tuned to the ISS Repeater on 437.8Mhz as it went overhead (according to gpredict). I couldn’t hear anything really, but I saw a signal sweeping in and out (doppler shift) as it would have been crossing over head.

Busy 40m

I used the fully-extended, large dipole kit and the RTL-SDR to successfully receive lots of 40m signals. It may have been especially busy, since it was Labor Day in the US and Canada. I found FT8 (40m and elsewhere) signals from St Lucia, Slovinia, South America, Cuba, and a little FT4 (40m).

I also found some BPSK31, RTTY/45, and still unidentified digital signals.
