One suggestion is to use NVIS antennas for those short HF hops.That's Near Vertical Incidence Skywave. Google will give you all the info.

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.
