Hi Jerry
Thanks so much for posting that excellent article – I had forgotten about it!
For those who want to understand more about geomagnetic lat/long and
gyrofrequency effects on 160m, it is just about the best article I ever came
across – and shows why 160m is truly THE ‘magic band’.

I tried a reversible BOG a couple years ago, and found that there was a
reason nobody talked about it;
the attenuation of the ground made the signal coming back along the two
wires MUCH weaker. I was using 16 ga copper landscape wire; I tried
several different impedance ratios but never co
Here is an interesting pdf document including information on the effects
of Earth's Electron Gyrofrequency on 160 meters.

Dear TopBanders,
I think the League's rules have not caught up with the digital age.
Four things have changed since the "analog age":
1. Noise is up
2. 160 meter DXCC (and up) is one of the last remaining HF DX challenges
3. Shared low-noise RX sites have become easy to build and for many may be

You can overcome the audio mute on TX issue with the SDR Radio Console and
Server software from Simon Brown. The Console software syncs with my rig
(TS590S) using Omnirig so can mute the RX audio on TX so you don't hear
your transmitted signal. Some rewiring of the headphone cable al
Hi Lloyd,
What you have described is pretty much what I have envisioned.
Personally I am still receiving at my home with occasional QRM from
industrial sources. DSP is easing the problems for me. The problems with
the gee-whiz approaches are centered around "latency". Tap your Morse

Hi Frank (and Rick)
Somewhere I have a map of the lines of geomagnetic latitude superimposed on a
Mercator projection of the world, but I can’t find it right now. Unlike the
ruler-straight lines of conventional latitude, geomagnetic latitude lines
wander across the world like a collection of s
It's the shared receive-only site that I will build for my club. I can't
think of a better application of subs for members who live in high density
housing as we do. LF is now completely out of the question for all but a
privileged few.
