[Elecraft] [K3] Broadcast interference on 160M

[Bill Frantz]

To follow up on an old message. I took the antenna down and 
inspected it. The connection between the feed line and the 
copper-clad steel antenna wires used galvanized hardware. This 
hardware was quite corroded. A private email had suggested this 
possibility. The corrosion was probably acting as a diode and 
generating harmonics from the AM signal. I replaced the hardware 
with brass. We'll see how long it lasts.
