Filtering call signs

That's great advice for users with powerful computers. My Raspberry Pi takes too long to decode. By the time a response has been displayed it is touch and go whether I can respond quickly enough to ha

Hi All, It is about stopping "Call 1st" responding to stations that you don;t want to respond to. If you call CQ DX and the guy down the road responds, capturing the QSO and preventing you responding

I am sure you are right, but from June 1st, some UK stations will be using the optional /70, with or without the regional indicator 'Q' to celebrate the Platinum Jubilee. For example, G7SAI/70, GQ7SAI

Why frequencies steps are not locked on 50Hz?
#frequency
To elaborate, if you consider the ft8 band to be 2kHz wide, that is 40 50Hz bands. The decoder can discriminate between signals much closer, I.e. overlapping. A 10Hz step can accommodate 200 signals.

Call 1st - filtering

Hi, Is there any way to filter the callsigns or DXCC that WSJTX will respond to if you have Call 1st checked. In these times of conflict some people do not want to QSO with operators in Russia or Bela

It might be worth asking the WSJT-X developers to add the option of setting frequency limits for each band. That way there would be no risk of transmitting out of band

Sounds interesting. Since WSPR is a narrow segment and we are looking at individual WSPR datagrams you could record signal strength and frequency from the FFT. I'm not sure of a suitable sample rate,
