Guys I have six or so CDM1250 in both low band 42-50 and UHF in both high and low spits. Although I think I'm having this issue on both the UHF and low band models I'm not certain about that. The issue definitely exists on the low band models.
The low band CDMs are programmed with tone squelch on all channels yet at least five times a day or more I hear noise somehow getting through the tone squelch as if the radio is programmed as carrier squelch. The strangest part of the issue is that while the noise is present if I press the monitor button....the noise stops!? This is consistent on the base and mobile units. I'm not sure if it's a "birdie" like anomaly of the radio design itself but it's driving me nuts. The Maxtrax, Radius and Maratrac radios don't have this problem and remain quite.
It's almost like the monitor feature is working in reverse.
This shouldn't be possible to hear anything through the tone squelch so I'm a bit baffled as to the cause.
I've checked the programming and can't seem to locate anything so far that might cause this issue.
Could it be an issue with PL vs frequency? I haven't tried a different PL tone to see if it still happens but I will soon.
Is there anybody that can shed some light on this issue?
Thanks
Chris
