Re: Changing the frequency of signal source at runtime

[Glen Langston]

Hello

Maybe you could share your .grc or python file.

I’ve had pretty good luck with gnuradio 3.7.13 and SDRPlay RSP1A,
where changing the frequency works fine.   

I’ve not gotten SDRPlay RSP1A to work with gnuradio 3.8, as they’re
not interested in following gnuradio changes any longer.

What gnuradio version are you using?

Regards

Glen
