Thanks for the quick advice everyone. The Terk has 4 channels, and I get the same interference on all of em. It's model LF-30S if anyone is interested...

There are 900 Mhz video senders out there, but I've read that they aren't very good... I think the 2.4 in a clean environment is really much improved...

Hiding cables? Very difficult in my place.

Talking to the neighbors? Good idea, and am going to try that - I would replace someone's 2.4 Ghz with a 900 if that helped, although I'm not sure they'd want that...

I'll keep y'all posted.
