VHF LoS (Line of Sight) would work over a distance of about 65 miles (curvature of the earth) and HF/SW pretty much world-wide, I suppose?

- walrus01 10y agoIn the real world, dealing with handheld and vehicle mounted VHF/UHF transmitters in the 2.5, 5 and 10W transmit power range, having local repeaters in high places like mountaintops or on top of 200m tall office buildings is extremely necessary for that repeater to cover even 1/20th of the land area of a western US state (WA, OR size).
- webtechgal 10y agoI was referring to stand-alone stations - as in those with a simple GP antenna (VHF) and a half-wave dipole (HF), where there are no repeaters or other external devices involved.
