Python Script for Icom PCR-1000 Receiver

Work in progress: creating Python code for the Raspberry Pi at Brough Astronomy so that I can add a second radio receiver to provide the much needed audio for a true "multimedia" experience watching meteor showers.

More WSPR on 40 metres

A short break from work gave me some time for more experiments using WSPR over the Easter holidays from my WFH desk with a Raspberry Pi and Yaesu FT-817.

I first tried using a Clansman E-VHF sleeve dipole which happens to work rather badly on 30m and 17m and then with a Maldol 40m mobile whip operating at ground level in the garden.


Despite the simple setup, I managed to be heard in Australia, New Zealand the Falkland Islands.  I've also learned the trick (from a DL) of calling CQ on CW on the same dial frequency which makes you audible at +700Hz whilst remaining outside of the WSPR audio pass-band at +1.5kHz.
