Kenwood beeping

[lrh270]

I bought a Kenwood 8360 on E-bay. It programmed just fine, but there is an audio "beeping" 2-3 times per second that I can't get rid of.

Any thoughts or suggestions? My local off-road shop says it's a radio issue, not a programming issue, but frankly I'm not sure they know any more about it than I do,

Post the radio information on the radio tag on the radio.
Did you program the radio outside of its working range?
Does it have a bad battery?
Versions and variations

• TK-8360HU:
  The "HU" suffix typically indicates a version for a non-European market, such as North America, with a frequency range of 450-520 MHz.
  
  
• TK-8360E:
  The "E" suffix denotes the European version, which operates on the 400-470 MHz frequency band.
  
  
• TK-8360M2:
  This version is also a non-EU model with a 400-470 MHz frequency range.
  
  
• TK-8360H:
  The "H" in the model name generally refers to a higher power output model, typically around 45 or 50 watts.

What is a vco and how do I unlock it?

2 things, wrong file or out of band frequency.
Still need more information to assist you.

What is a vco

Voltage controlled oscillator. It's the thing that generates RF.

and how do I unlock it?

By programming a frequency that is outside the designed range of the radio.

That's why Evans is asking for the file. He needs to see what you have programmed into the radio and compare that to the capabilities of the radio.

The TK-8360 is -only- spec'd for 450MHz to 520MHz. If you try to force a file into the radio that has frequencies outside that range, it's going to complain. If the programmed frequencies are too far outside that range the voltage controlled oscillator (VCO) will not lock and the radio will start beeping to tell you that.

What frequencies have you programmed into this radio? Did you try to put VHF frequencies in? Did you try to put 70cm amateur radio frequencies in?

It's also possible that the radio is out of alignment, a previous owner diddled with the alignment, or some component has failed.

Just for clarification:

You want the VCO locked.
Unlocked VCO is a bad thing and the radio will not work.


Locked = good
Unlocked = bad

Thanks everyone for your help.

The root of the problem was that I.m an idiot; I was trying to program VHF freqs in a UHF radio.

Thanks again
