[Moon-net] [Fwd: Astonishing measurements on 24GHz and 10GHz]

[Al Ward]

Per
Barry VE4MA and I noticed similar characteristics 7 years ago when we made
our first EME QSOs on the 24 GHz band. Barry and I are looking forward to
working you this month. My new 2.4 M dish is working very well on 24 GHz. I
should have the 100 watt TWT going shortly.

Hallo,


because there are nearly no partners for QSO on 24 GHz, I started three 
months ago to look for my own echos on a daily basis. Normaly the echos 
are about 100 to 150 Hz wide. On average one to two days after the 
moon's perigeum, the echos become as narrow as 20 to 30 Hz. This 
happened each of the three months. When I looked for it on 10 GHz I have 
seen the same effect.


Firstly, I am very interested to hear an explanation.

Secondly, days with small echo are very good for QSO because 
signaltrengh and readability are much better than on all other days.


Pictures of the signals can be found on
