I tested the new firmware with my K3 + Ptc-2 TRX modem built inside the 
K3 and I think you have made a good improvement with the latest firmware
2.82. 
The output measured on my LP-100 meter is in a 5% range close to the 
power setting of the K3. I had to set the LINE IN GAIN higher than before, it 
is now at 20, before it was at 12. My output settings in the TRX-PTC 
modem are set to 1000mV for PSKA and 800 mV for FSKA. TXG VCE is 
set to 0.0dB This combination gives me the recommanded 4 bars of ALC. 
Throughput is good as far I can tell - I'll have to check this in the evening 
with better conditions to the RMS oe3xec which I can connect on 80m in 
distance of 280 nautical miles. 

thank you very much, that's what I like with you and the K3. It's getting 
better every time ;-)
