Is causing danger to another aircraft on the ramp via an HF call a left over war time hand me down wisdom (like birds and radars) that may have been true once but is now obsolete?
We are not allowed to use our cellphones at petrol stations, and they are much lower power devices.
HF ground testing has probably been safety audited, but just a thought: The distance from your aircraft fin, (where the HF antenna usually is), to your fuel tank vents is not much different to those of the aircraft next door, on some ramps.
