[GCARC] HF, bats, azimuth

[Todd Foster]

Thanks, Tony. I'm unaccustomed to having access to a Yagi! I'll keep the 
90 degree nulls in mind.

Big antenna, big radio: that's a luxurious station.

Thanks for confirming the standard compass orientation of the rotator. I 
found an Azmuthal map at: https://ns6t.net/azimuth/
