More than anything else, I suspect the radio you're using to listen, John. Even newer made-for-ham rigs have problems with not having good filtering of CTCSS tones. My Kenwood 742 lets some through, especially with the MCS-2000 speaker I have on it (since the internal speaker is next to useless in a service truck ;c) The handhelds of late have been much better in that regard, mostly just because of the cheap speakers they use. I remember an old guy complaining about hum on a repeater I put together years ago. The repeater was of course running encode on input carrier. turns out he had a 12" bass reflex guitar speaker plugged into his 2M rig. I told him to fix his rig and go away.
