Nothing heard over Seattle this last pass.  However my max elevation was only about 5 degrees.  Rx is a three foot primestar with a 3731aa downconverter.

AO-51 is currently in Mode V/S on 145.88/2401.200. With our attitude 
inverted from normal, I'm interested in any S band reports. The L/S 
antenna should be pointed towards the ground now in the southern 
hemisphere, and away in the northern. The schedule indicates we would 
concurrently run the 9k6 telemetry downlink on 435.150. Due to low 
battery voltages and being near the bottom of the output power selection 
range, I shut off the 435.150 transmitter this morning at about 1025 UTC. 

Please send any reports on the Mode S signal to ko4ma at amsat.org. or 
ao51-modes at amsat.org. 

Thanks, Drew KO4MA
