I would like to ECHO the frustration of Patrick in copying the downlink signal of AO-51 (no pun intended). Setup here is tracking EL-AZ M2 436CP30 antenna (albiet RHCP which may account for some of the difficulties). So far I have ONE PASS that I was able to copy a single ring of the beacon. Maybe a preamp is in order, but sure would be nice to get a consistent DCD on each pass. My array is well aligned as I have logged probably 50 to 60 contacts on AO-40 L-S. I have tried switching the 436CP30 over to LHCP but, sadly, corrosion on the allen screws has so far prevented such. Anyone else trying to copy telemetry with RHCP? Thanks. Jim N6FO

I would like to report very poor reception of echo even with an 8 element yagi and an 18 Db preamp. I assume the downlink power is real flea power for battery charging or other testing.
After 2 years of pleading with amsat, the downlink power is still a mystery. It is not shown on the colaradosatellite telemetry graphs (TX B) or the amsat website, after repeated requests here and elsewhere I'll assume it is being held secret for some reason.
There has been a tremendous lack of technical reporting on ECHO.
I realize people are very busy but time should be taken to educate the amsat community.
