Notes on EME RX

I knew 2m EME was possible with basic equipment nowadays thanks to WSJTX. I did not know how to go about it. Thanks to Jim, GM4FVM, I now have a clearer understanding. Although I have decoded one station on the 'uplink' so-to-speak, as yet I have not decoded anything from above. However this might well be due to the 20m of RG58 between the radio and the antenna. The thing is even though I have a basic idea of how to go about it, today, I also know I shall soon forget. So I have listed the basics here:


WSJTx in JT65 mode B (make sure you have VHF features enabled. I know you forget)

Find The Moon

Enter your location and this site will tell you where to point, and when. It is very good and the Moon appears to do exactly what this site tells it to do.

This tells the Moon where to go in the sky. I like the arrow.

It's there!

Note how the times shift each day

Find A Signal

Quite a frantic place. Watch carefully for the CQ frequency. Tune there and allowing for doppler (I guess if you have F Tol set to 1000 that should cover it) perhaps you will hear the station call.

Look someone is calling on 144.131 - 4x crossed yagi and 500w


I found some of the spots appear here. However there is some strangeness in that some appear as JT65 and others as JT65B. Nobody knows why. Some even never appear.

'Elevation: If you are bound to "no elevation" (no vertical rotator available or no manual means of
adjusting the antenna elevation): You'll have a very limited choice time-wise for EME operation as you'll be only able to run 
EME QSOs up to a moon elevation of some 20 degrees. This may include a moon window of operation of an hour+ or so at moon rise or set.'

Excellent Notes Here...
