[amsat-bb] SO-50 question

[Loren M. Lang]

Most satellites I have 5 presets for with +/- 0/5/10 kHz offsets from
center on the 70 cm band. With SO-50, it's 6 with 5 being setup with the
usual PL tone of 67 Hz and one marked with an A for activation and set to
transmit the 74.4 Hz PL tone to quickly select it if I don't hear people.
