[600MRG] WA2XRM/166 extends out to 20 Wavelengths

Thu May 25 12:08:15 CDT 2017

Greetings, all!
Dayton debrief here.

Had a great forum on receiving antennas....excellent response.  I passed out over 100 QSL cards to attendees.   Talked a bit about ELF, antennas and Lock-in amplifier techniques too.

One of the projects I'm looking at for 2200 meters is an integral cycle (zero crossing) CW transmitter.   If you key a sine wave precisely at the zero crossing, you won't generate any sidebands or harmonics.   Any decent function generator has an integral cycle burst function.  I want to try this method on the air.

Stay tuned!
Eric

Hi Paul,

Perhaps you could monitor your signal on some of the web sdr receivers. Surely your signal should be audible to many km.
For example there are several KiwiSDR’s that may be w/i range of you. See
http://sdr.hu/map (double click on the map to zoom it in).
One of them is W0AY in MT

I just tuned his KiwiSDR to 166.66. His noise level is pretty low on LF. 

There are a number of other web sdr server types.

Are you TX every night?
Can you use WSPR on 166?

73,
Roger
