Re: AO-51 back in mode J-FM (and VERY busy)
Nope, the alligators are the ones that are transmitting without listening. I'm sure you're listening if you are making contacts! :)

I have noticed that most of the trouble seems to be powerful alligator stations that cannot hear the downlink and boost their uplink power to very high levels while calling long CQs. This wipes out those of us trying to make contacts with HTs.
On the whole I have found that regular satellite operators are very courteous and keep their contacts short, allowing everybody a chance to use the satellite.

Please don't send them over to SO-50 to 'talk at length'. Too much of that is observed sometimes on the weekends now. :)
Part of the trouble that I observed with AO-51 is some stronger stations (without PL) or illegal cordless phones, are blanking out the uplink. I
had
trouble after the switch to V/U. I usually run 2 watts to a CP KLM beam. Even with the rig boosted up to 45 watts, I couldn't overcome whatever/whoever was blanking out the sat most of the time. Out of two passes this morning, I made only one contact. Lots of stations on, but
only
the strongest seemed to make it over whatever was blocking us. Strange
that
I didn't have that trouble at all when it was in V/S mode earlier.

Down this way, the alligator problem is caused by stations with inadequate receive setups. Mode J is certainly not a roaring success on this side of the world, because most ops don't have a dedicated satellite setup, and conditions strongly favour the uplink on Mode J. I was using a handheld Yagi, so for me, the downlink was solid, but many a QSO has been clobbered by someone running high power on the uplink and hearing nothing coming back down.
Mode B (a la SO-35) was a huge hit down here, with few alligators. :)
