hello all, I have a wierd issue with my cdm1250 vhf, I did some changes to a few pls and reprogramed, now when I tx on a certen channel it gives me this funny sound like a batt going dead on a ht1250 and then my mdc will key up, the radio seems to work ok both tx & rx I can't seem to find a setting for this and it is only on one channel no others do it, any help would be appericated

Thanks Jeffrey

The votage/amperage of the vehicle's battery or/powersupply is too low.

I had a CDM1550 that did this and found out the powersupply had a max amperage of like 9amps. I would recommend a source with at least 20amps.

Check the power settings for that channel as well in the CPS. It may be the "one channel" that's programmed on high power, which may draw too many amps.
