So, to be clear, you're saying that the flood of PFS3-1, -11, -12 packets is only initiated by a PBBS user's uplink, and is not autonomously initiated by the satellite based on time, location, insolation, or some other stimulus that is not communicated to the satellite via the 145.840 MHz uplink, correct?

I'd agree that the attitude of the satellite affects link margin, given the geometry of the antennas in the satellite drawings I've seen.
This FS-3 pass I just tried must have had a lot more PBBS traffic, not quite as much as Wed or Thu, but much more than two hours ago, maybe one packet every 2 seconds or so. I wasn't iGated, despite sending my beacon several times manually. If the downlink is this full of PBBS packets, is that clear evidence that the uplink is active, since only a successful uplink to the PBBS would trigger the flood of packets?
