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@amsat.org. or ao51-modes@amsat.org.
Thanks, Drew KO4MA AMSAT VP Operations
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.

0404 EDT pass i was alone signal good S4 S5 start to copy at 12 deg 0612 EDT pass start to copy at 8deg copy was peaking at 20 db over my noise floor signal only interrupted by blocking object. It was a 65 deg elevation pass here. Made QSO with N8BBQ Edward and N8MH Mark
Near the end of the pass a rapid pulsating tone carrier appears it was just at the same level as other signal at times.
As per my test S band signal is lower at this attitude on low pass to a point to be weak to be received. Depending where the satellite is also made a big change in the signal strength when he pass my latitude on one occasion the signal increased by 1 s unit "-"

Hi Drew
Worked KB2M and WB8OTH on 21:30 utc pass however no downlink signal until it reached about 30 degrees elevation then sigs picked up to about S7 max which is 2 to 3 S units lower than before.

Pretty good signals on 2.4Ghz in Seattle CN87wk. Some deep fades, though could be the bird passing behind several trees (need a bigger dish). Rx 3 foot primestar/3731aa downconverter. Next pass will try a Keps dc.

On the 1809 pass from AOS to TCA i start to copy at 12 deg but signal came much better as soon as the sat pass my latitude Signal became as strong as before S9 but with deep slow fades. from TCA to LOS i was able to hear my downlink until 4 deg. West pass are much better here than the east one where i was not able to get anything with a 10 deg max elevation.
I made 3 contacts KB2M W7LRD and WC7V and someone was sending a lot of carrier all along the pass??? there is no need to transmit to be able to received S band as the transmitter is always on. "-"

435.150 is back on at 270mw with 9k6 telemetry. V/S is also working now. I'm still interested in reports on S now vs before the magnet reversal.
