I have a question now about the FRS Radio codes and sub codes. I have a Real early FRS and it is CTCSS not DCS and is an off brand so not sure if it is using the same frequencies. (There is no standard in the industry) Mine is Channel 10 467.6125 MHz and for code (sub channel) 1= 67.0Hz, code 4 = 74.4Hz and code 5= 77.6Hz.

Is this compatible with the ones listed that you talk about or would mine have to be some other code
.
