All stations, please QRP!!!! From everything I've read about the behavior and history of the satellite and heard from other operators monitoring these passes, stations running excessive uplink power are responsible for the recent mode jumping.
There are AMSAT demonstrations scheduled this weekend that are relying, in part, on AO-7 being in Mode B. Please keep your uplink power to no more than 100W ERP. If you wish to calculate your ERP, please consult this page: http://www.csgnetwork.com/antennaecalc.html
If you cannot hear your own signals with 100W ERP, please QRT and make improvements to your receive setup.
Thank you,

I have been operating W1AW /5 this is Joe N5JF in southeast Louisiana AO-7 turned off while I was operating yesterday and today I don't own an amplifier and I've only ran under 25 Watts with the TS 2000. I would think the idea of theQRP is a good one
