Having a problem using any channel above 4 on my TK3101. All I get is a tone that doesn't change when I key either monitor or PTK button. Do not have as I set up quiet tones on all channels, but as soon as I finish and turn radioes back on I get the tone. Both units are set to same quiet tone.
Personally I dont Know this radios, but you said that above channel 4 you get a tone a continuos tone I guess, I think that this radios has the PLL unlocked, that is a problem related with the circuit that generates the frequencies.

I have worked on the TK 3101's and that tone is when the channel does not have a frequency.
It is a PC programmable radio. I assume you purchased the radio used and the previous owner had channels 5-15 "blank"
I can program it for you if you needed.
