Hi Michael, I've managed to reproduce the issue by setting up my FT-817 with a SM1000, and some powered speakers so I could leave it running for a while and hear it from the next room. It's "breaking squelch" for me a few times a minute. Might be signal dependent too, ie what sort of background signals there are on the band.
Would be nice to fix this, so the SM1000 can be left running like a squelched FM radio. I'll think about how to deal with this, will take a few weeks to fix. Steve - thanks for your suggestions too.
