Tk 830 constant speaker output
when power radio up get the normal beep, than it has slight hum and can hear faint beeping. Does not change with speaker volume adjustment. And when receiving sounds fine. Anyone got any Ides? Basicly sounds like an open mic.
Re: Tk 830 constant speaker output
On any particular frequency?
Re: Tk 830 constant speaker output
Changeing the channel doesnt matter, volume doesnt matter. It stays the same, until someone talks back then it sounds normal
Re: Tk 830 constant speaker output
Try disconnecting the antenna and put a dummy load on it if you have one. If the noise stays it's something wrong with the radio. Also just thought of this. Is it mobile or in a base setup? Does it change with location? If mobile does it change with engine on or off?
Re: Tk 830 constant speaker output
It is a mobil unit, I didn't have an antenna connected when I did this. But I think you are right, I think there is a problem with the radio. Problaly why the person sold it. EEEERRRRR Pisses me off. I sent an email to kenwood requesting info on sending it in for repair. I am thinking a relay n the board is stuck on or something. Sucks, I have a tk 730 g but the board wont work in that on I dont think.
Re: Tk 830 constant speaker output
Might be pretty spendy to have fixed. That's a fairly old radio now.
Re: Tk 830 constant speaker output
Ya it figures. But already have money invested. why stop here.
Re: Tk 830 constant speaker output
Well I figured it out. Was interference From the truck. Ran pos and neg straight to batt and sounds fine.
Re: Tk 830 constant speaker output
Excellent work! Do have it hooked to ignition sense so it goes off with the key?
Re: Tk 830 constant speaker output
Thats the wire in the back of the head? Because I tried to hook it up to a hot when key on and it didnt work. I dont mind shutting it off everytime. I am just happy I dont have to send it in for repair!!!!!!!
Re: Tk 830 constant speaker output
Here, go to this guys website and read up on how to make it work with the ignition. It's fairly easy if you are comfortable opening the radio and going at it with a wire cutter and soldering iron. http://www.eurekaboy.com/tk730/tk730ignition.htm

Re: Tk 830 constant speaker output
I would be curious to know what in the truck is making the noise. Could be a sign of bad grounds, bad alternator or battery.
