[Elecraft] {OT} Alexloop Walkham Antenna

[Enzo Adrian-Reyes]

People seem to have good opinions on the AlexLoop, but I had one feedback
into my KX3 and forced it shutdown, I've heard of other similar things as
well with magnetic loops. The thing to remember is that you need that ATU
off before it can work.

On 40M I couldnt even get a signal out, and other frequencies here in VK
are dead except 2m/73cm

73
