Hello,

i updated today my QRP to 4.0. Since this time i had several times the same fault in the Receiver.
After some TX´ing the receiption level decreases dramatically over the whole spectrum. When i press TUNE (as an example) or restart the Software everything seems OK.
I have this Problem on 2 PC´s with different settings.
Never had this Problem before v4.

Any ideas?

Hello,
can I use the older Ver. 1.1.2 for the SunSDR2 QRP ?
Because the beta Versions are not working in FM Transmit.

With the SunSDR2 QRP is still no FM modulation possible on 10 meters with ExpertSDR2 1.2.0 beta6. I use the ports on the front of the SunSDR2 QRP.

I've noticed that the problem with the FM modulation affects only the Mike 1 port. FM with the Mike 2 connector is no problem. :music: :hi: Perhaps it is due to the "block DC" setting. :unknown:

I found a new bug concerning the FM modulation. The "high" setting in the TX menu is practically limited by the deviation setting. The bandwidth should actually be 2x (FM deviation) + 2x (LF frequency).
That's not the case.
