I’ve just discovered a nice tool for plotting radio transmission coverage. Here’s where I can expect to get a signal too from my home location.
Yellow shows 0.50 μV signal level, Green is the 1.58 μV signal level
This seems to match up quite well with contacts I’ve had on the two-meter band, but with less power actually used. I’ll have to play a bit more and see how it says my station will perform on other bands.
