Hi
4:30 CDT
100% copy this time on 30 meters. The radio is now an Icom IC775 on 30
so the S meter is a bit different than the RF-590. That said the meter
has the net up to an S-8 except in fades. That's a whole lot more
signal than on 20.
Still gotta find the audio input cable for the 775 ....
Enjoy!
