Many thanks Tom

I can probably extrapolate from those numbers.

I haven't looked at the ISM/HiFER rules/regs but the QRSS type mode
itself is going to be maybe 20-30dB "better" than SSB. I guess I'd be on
par with your numbers at 100-200mW o/p
Cheers Bob

vertical made from half a driven element from an old tribander. We are
both running 100W SSB, and the received signal levels are just enough
above the noise level to communicate. The terrain is relatively level,
and the path is from the western Minneapolis suburbs to a town southwest
of Minneapolis.
