Would add 10db gain... would have ot use the calculator to see if it is enough... beam width on the moon is wide, 5 degrees... so your TX power isn't all making it...


EME Calc says that setup with 30 watts your end would be -11db his end... those figures are usually a bit optimistic! I can't run a calc for the looper... not easily anyway...

I do have a 1.2 meter offset dish that would have been much better, but no 9cm feed for it.  It was a spur of the moment attempt using what I had on a 24 hr notice.

Fun isn't it! To bad you don't have a small dish! 4' would have done it!

HB9Q posted that they are loosing the 9cm band starting in 2024 and they were looking for any last initial EME contacts on that band.  Dan has a 10m solid dish and 100W at the feed and said "You only need a minimal station to work me".   Well, ..... I have a minimal station!   How about 30 watts and a 5 foot loop yagi, 20 dBi, my rover antenna?  After setting up my "rover stuff" in the garage and mounting my mighty 5' looper on my Az/El mount in the driveway I met Dan on the HB9Q logger and we gave it a go.  My setup was a DB6NT transverter converted from 3456 to 3400 via a LeoBodnar GPSDO, no preamp, and a Tosibia amp.  The antenna was fed through about 5' of LDF4.  The good news is that I did get a number of decodes from Dan, the bad news is that he never got any decodes from me, so no Q.  Q65C-60 and Dan was doing all the frequency correction on his end (not to mention all the heavy lifting).  So despite the no-Q, it was fun to see HB9Q decodes pop out of the ether using a very minimal system (on my end).
