K3 on VLF

[David Andrews-3]

Dave

 

I use a battery-powered Heathkit unit I bought off Ebay. Tunes 3.5-4.0Mhz
(0-500Khz). Datong made a similar one though I've not tried it.

Hi Dave,

 

You need a BC-453.

I am currently using my k3 succesfully on 500khz. Since arriving here last
saturday I have heard 3 signals while listening on a casual basis out to
650km

I using the amrad active antenna in the roof space, but am building a tuned
loop for 136/500khz

I am a K3 owner and user. I have the KRX3 module installed. What do I
need in order to hear  below 500 kHz? Or is this even possible for
the K3? Currently, there is a great signal drop off when I tune below 1 mHz.

Dave, W5U

I've heard a number of beacons on 600m. YWA, in Petawawa Ontario is
usually pretty strong here, 500 miles away. Plus lots of NAVTEX
stations on 518 KHz-- typically clean copy of New Orleans, 1200 miles
away.

I'm using my main transmit antenna, a 100 ft wire. The ATU is in LCSet
mode, the elements tuned to CA=0.0 (min), L=17.35 (max).

73,
