With LSB and ~2kHz tones it's actually back *in* the band with modulation.
HF packet is FSK, and the mark/space for APRS are at 10.149.200 and .400.
When implemented as AFSK + LSB + modem you have to take into account the
modem tones, which vary considerably. In fact, you can use USB and tune
below the band as well. If you google "hf aprs" you'll find a bunch of
tables for various radios and TNCs.

Ah. Makes sense.

I do direct FSK so have been taking carrier frequencies literally. (and
haven't done datamodes, except CW, on 30 meters so I'm not familiar with
APRS practice on that band)
