How do you determine the channel frequencies and pl tone codes a radio is set to? Specific radio would be a Kenwood TK-3200L (K3 ).
Here is a link to the operating manual for that radio. Pages 21-26 should tell you everything you need to know about getting your freq’s and PL tones.
OK, so this is the low tech way of doing it, which while effective can be a pain especially if the radio is not set up for simplex operation (same frequency/tone to transmit and receive). Get someone with a scanner to narrow down the frequency to the channel selected on the Kenwood. Then from there a cheap Chinese walkie with PL tones can be used to narrow down the exact tone if there is one. The easiest way? Take it to a dealer, they will be able to tell you exactly what it’s programmed to.
