RxRx _ RxRx _ RxRx _ RxRx _ etc, etc
... where Rx is a nice strong (or even a not so strong) signal of 2secs, and _ is a 500ms drop out? I'm guessing at 500ms, but it's certainly less than 1 second.
This seems to be FM related, and does not occur when I'm listening to Aircraft (the AM signal).
It's kind of annoying more than anything else. And it's not that I like to snoop on what others are saying; in fact when I hear chatter of an evening that's clearly between guys that know one another, (on 2m, for the most part), I hit the Temp L/O, and continue my scanning. Signal and equipment checks are more interesting to me, and I get some idea about where these guys are and the Tx/Rx distance.
Edit to add: it's not Squelch issue, btw
I also get this consistent pattern when there's just a carrier wave, as with 914.6000 MHz: hisss _ hissss _ hisss _ in 2sec, 500ms intervals.
