ES5TV 21 Mhz EME 13 jan 2013

Описание: After two fruitless attempts at moonrise I got 21 Mhz EME QSO with myself done during moonset with the new 8x5 element H frame antenna.

This is the video of the best minute out of ca 10 minute period the signals were audible with strong QSB on January 13th, from 1615 to 1625z ca 2 hours after sunset:

Moon was setting at ca 243 degrees azimuth and the signals were audible while the moon was from 3.3 to 2.2 degrees of elevation peaking at 2.6 degrees. Antenna was pointing within 3 degrees of the correct direction. Radio: FTDX5000 + ACOM2000A.

It is noteworhty that the band was not 100% closed as even some SA signals were heard. Also the amazing strength of the signals at expecially the 3rd time the signals come back is probably also attributable to some ground gain at this elevation.

I wish I had also tried SSB and maybe the 4 high tribander stack for comparison but was too excited to remember. Should also try if changing the radiation angle to say even 30 degrees would allow hearing moonbounce from that elevation. Next time:)

Now all I have to do is to find someone interested in attempting real 15m EME QSO (anyone done that before?) who would have coinciding sunset/sunrise and high gain antenna on 15m.

Can anyone recommend a good program that would picture moon grayline (like DX Atlas for sun) that would enable to easily

Here is also the high resolution video of the tower erection put together by ES5PC. It also includes the very first QSO with the new stack with Paul, K8PO:
