It's good idea to have a watchdog alerting when busy on antennas.
DX Bulletins
Below a tribute to the company over 4 decades of DX'ing in Alaska and... keeping those pesky moose out of the antennas.
Corgi partners now gone, time flies.
My current moose chasers below; a blue eyes merle American Shepard (Mini Aussie) and another Corgi (his name is Shorty). Living with two herding breeds; they run the place, the wife and I just live here!
P.S. I went to the dogs long ago, used to mush my dog team in the early 1970's but had no ham radio gear involved. One never forgets the serenity of mushing a team of huskies and the nostalgia of another era.
