Should I be able to hear AO-51 using an eggbeater with no preamp?.
I can hear VO-52 just fine but have not heard AO-51at all, so I have to wonder why. I'm listening on 435.15. Perhaps the sat is not active while over DM03? Or am I kidding myself thinking I should be able to hear it without a preamp? I realize the VO-52 downlink is 2m as opposed to the 70cm AO-51 downlink. I'm having my preamps repaired but until then I could use some advice/opinions.

Your eggbeater is probably RHCP overhead and horizontal at the horizon. The 435.150 downlink on AO51 is LHCP, so you are at a serious disadvantage. Can you hear AO27?

No I have not heard AO27 either, that explains it. Time for different antennas. Thanks for the info! ----- Original Message ----- From: Andrew Glasbrenner To: Paul Delaney - K6HR Cc: amsat-bb@amsat.org Sent: Sunday, October 02, 2011 12:47 PM Subject: Re: [amsat-bb] Hearing AO-51

Hi Paul,
Do you by chance have a dead preamp inline? I've had some fail that keep any signal from passing...it's worse than no preamp!!
Just a thought...
Drew's comment about polarity is a good one, too.

Hi Mark,
Yes, the dead UHF preamp is still inline, but I was unable to hear AO-51 before I put up the preamp. I added the preamp (a bargain buy on ebay) but the preamp only worked for a few days before going dead. What do you think about an Elk at a fixed elevation on an azimuth only rotator? ----- Original Message ----- From: Mark L.
