I tried to adjust the QRG by modifying the 27 Mhz and the correction was very different from what I expected. RBN may not be the perfect reference but RBN was indicating .2 higher.
In order to get that down I went from the initial 27004 to 27007. Now RBN is spot on. So at least I am closer to the true QRG. Strange I had to go up to make the QRG go down.
So one thing fixed.
Apart from CAT still S Meter and Decoder to be fixed. Decoder actually it gives a row of Ts. I would have expected it to decot?de at least my transmissions. C 40 not yet verified, too lazy to open the housing,? to poke the developement board out and measure.
