[aprssig] HF options

I've had an inquiry about a project that would involve linking fixed 
APRS stations at intervals of maybe 50 km, with not much chance of 
digipeaters.  Without favorable terrain, that seems a little doubtful 
for direct VHF.

I've done very little HF myself in the past decade, and I've never 
worked HF for local (relatively speaking) communications.  Can anyone 
suggest bands and equipment that would work well for this, assuming 300 
baud AFSK is used?  Power consumption is a major concern.

Thanks,

Scott
