Oh dear, yesterday morning when I switched the SunSDR2Pro on, I found there was only a very low (0.6W) power output, even with the Drive slider on full power.
I tested it on CW, SSB & RTTY all with the same result. The RX is working fine but the TX is virtually dead.
In the EESDR2 display the rig appears to be keying properly but only 0.6W out.. Similarly if I click the TUNE button, there is no output.
I suspect now that the PA transistor might have blown but what tests can I do? Is it worth trying the Reset button I wonder?
Any advice please?

I feel a bit stupid!
Sometimes the simplest explanation is ignored (by me anyway!) . When I put the SunSDR2Pro on again today, I noticed the PSU was only supplying 3V instead of 15V. Changing the PSU with one with the full voltage "cured" the problem.
Sorry for the bandwidth
