The oscillator in the Herring Air 5 is very bare bones &#8212; no buffering and an LC circuit that is mostly L (10 uH). It became very difficult to get a stable amount of CW offset. So I went back to crystal control for the transmitter. I did replace the 5K tuning pot in the RX with a 10k 10 turn pot (thanks to W8NSA). Tuning is now very smooth. I used my old UK freq counter to monitor my receive freq. (Thanks to Tony Fishpool G4WIF&#8211; back in 2009 he sent me the CMOS chip that brought this counter back to life.) <\/b><br \/> <b><br \/><\/b> <b>I was putting out about 750 milliwatts. <\/b><br \/> <b><br \/><\/b> <b>I had a very quick contest-like contact with K2D &#8212; one of the &#8220;13 Colony&#8221; stations.
