I use a home brew mag loop on 30 m band and work into Asia most mornings with it. The loop tunes to a near perfect match (1.00:1 SWR) but becomes instantly detuned when a dove perches on top of it. SWR jumps instantly to > 3.0:1 and trips my High SWR monitor. The birds look stupid but they are smart enough not to straddle the loop opening. I imagine full loop voltage between their legs would de-tune them a bit but they just perch one side or the other.
Damn dove nearly cost me a QSO with JD1 this morning and that was new DX for 30 m. I tail ended with FT8, he came back, I started to send my report, High SWR trip, run to back door to chase the dove away, and got back before JD1 had given up on me. So how to keep birds of a mag loop without lowing the Q? 73, Andy k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
