My 6300 is just back from the Radio Hospital for a problem in the TX (no output) which is now fixed. Q5 and Q6 were blown, repaired under warranty. There is one minor issue which might have been there before or not, can't be sure. Running SSDR 1.7.30.
In RTTY mode the default MARK frequency shown on the DSP button on the "flag" is 2125. No problem, works great. The problem is when I change it to something else such as 1275, which I prefer. With that setting there is no RF out. Even the TUNE button gives no power. I get the feeling that even though the number has changed, the DSP bandpass is still set at 2125 and that's why no drive is getting through. I could be wrong on that, it's just a guess.
All suggestions welcome.
