Topband: Frequency Dependant Remote antenna switching

[Tim Shoppa]

Along the same lines:

W7IY had a very nice article in September 2017 NCJ, where he shows how he
uses an ESP8266 WiFi module (circa $2) to remotely switch 80M antenna tuner
coils in and out as the rig QSY's around the 80M band segments.

N1MM+ sends UDP packets containing band and frequency information, which I
use with my own ESP8266 band relay switching.
