 Preset takes some time to change but it may be better than pressing APF.

With APF I was able to copy many weak stations on K9AY when running. Notably
KH6 and KL7, plus a few WI stations, I guess,  running 5W with mobile
antennas.  But if it takes 1 sec to turn on APF, and an average station
calls once, one cycle is lost. After a weak station repeats a few times,
other stations decide to use the same frequency for RUN.

I find RIT good enough for APF, and faster.
