Malahit DSP2 SDR demonstration

ISS Doppler effect
Просмотров 2765 лет назад

The sound was monitored at my QTH using a Yaesu FT-991A and a Moonraker SQBM1000 colinear aerial; the on-line SDR display was from the Farnham SDR; the ISS pass...

More fun and games at the EARS SSB Field Day in September 2018. We increased our logged stations by 25 over last year, and ended up 9th out of the 23 entries in our section, with a much lower error rate than the contest average. Also, the barbecue was excellent, as always.
