Hi, although I use my R4C mainly for CW reception and use the PBT tune control so I listen to a lower than normal audio frequency maybe 300 HZ, my CW qso's usually don't last too long to detect much drift of the vfo.
Has anyone checked the long term stability of the vfo?? and what results did you come up with ?? Apart from the ARRL CW practice runs, is there any CW traffic about non amateur in the English language??, it was nice many years ago to pick up the wx reports on CW on marine band frequencies. 73 de ian G3YRQ.
