Wondering if there is a way to crack open the global sets list to edit the freq manually so the software doesn’t have a chance to touch it
You'd likely be the only one on that frequency, and no one would here you. (actually, considering how close .21875 vs .2185 in your example are - you might hear some of it) , I'm leaning towards you having the incorrect information for that system.
I'd verify either with the system operator/contact what the frequency is, or present the correct listing in the RR DB so we can figure out what frequency you're really
supposed to be on.
There is a hacky sort of way to use the "close but not exact" frequency when you are using NFM splinter channels on older WFM hardware, where you would program in the closest correct frequency and then listen in wideband mode - you would hear most of the conversation, and it would usually sound terrible - but it kind of worked, but not in this case.
