I am working on a code plug for my one radio and I have a pretty extensive code plug already that has basically all the talk groups etc etc one could ever want. BUT. All of the channel frequencies are wrong -- on the UHF side I am using it with My shark RF-- and want all of those on one freqcy but  the code plug is set up on another. Rather than type in 436.0000  two thousand times or such I wanted to maybe open the file in like excel and do a "find"
and "replace" but the .rdt file is ??? Is there a way to convert them to csv or open the raw data in a usable format that can be manipulated easily?
--I cant do it in N0GSG contact manager tried a couple of things there already and hit a dead end until he releases a dual band version.
