[Elecraft] K3 Below 500 KHz RX Antenna

[Milverton M. Swire via Elecraft]

Jim / Don, thanks you both for your input. Albeit brief, I now have food for thought and some bedtime reading to do on Beverage antennas .

I don't completely agree with that. I have a pair of 2-wire Beverages 
that are approximately one wavelength on 160M. I use them on the AM 
broadcast band and find them quite effective as RX antennas. They are 
not as directional on the low end of the band, but they still have SOME 
directivity, and with the DX Eng preamp, they are quite sensitive.

After installing my new synth boards in the radio with the KBPF and 
doing the mods, I tried listening down to 100 kHz. Around mid-day, I had 
good copy of a CW beacon about 125 miles away. These antennas are too 
short to be called Beverages at those low frequencies, but they do work 
well as RX antennas.
