How's your noise floor. I have the same issue here. the 1/2 watt TX is barely enough when I'm at home (urban area) and due to a high noise floor. When I'm out in the country, I don't have problems hearing the 1/2 watt TX with the same arrow antenna setup. If this is a fixed setup, perhaps a bandpass cavity on the RX would work. I don't know how well this would work in satellite doppler but it's very effective at removing intermod on my fixed terrestrial APRS station.

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.
