Have been doing some simulations on 3.5, 7 megs on the new mode

excellent coverage 0 to 1500km daytime.

assumptions :

TX :5 watts,  -20dBi, 1% efficiency... approx hemispherical down to 20 
deg elevation

RX noise level ~ -25dBuV/m @ 30 degS, summer, about S3 noise on a dipole 
in a SSB bandwidth on 80 meters.

quite alot of margin all but middle of the day on 80m.

suggest use 40m from local noon through 7pm in summer.

should also survive a static crash....
