As always Tim, the voice of reason :-D
I tried to work you on AO-51 last night but it was the normal zoo!

David and all,
I'm confident someone will correct me if any of what follows is in error.
I believe two elements are at play during passes when the ISS repeater is active.
1 - Doppler-tuning on the transmit side is important.
2 - I suspect the squelch is set somewhat on the radio up there; otherwise, I doubt anyone would get through at all.
My sense is that the "jamming" you alluded to has more to do with people who are transmitting with decent power levels who are hitting the repeater but are slightly off the uplink frequency. That, plus some whose signals barely break the squelch.
And there I was ... out in the front yard with my VX-7R set at 50 mW out. Like THAT signal has a chance!
I'm gonna keep trying, though, whenever I use the HT for a pass.
73 to all,
