TK-8150 Loud Burst of Static After EOT

[kenwoodgeek]

Today, I acquired an older Kenwood TK-8150 that was installed in the school bus I ride, after I traded an extra NX-800 unit I had to the bus company to be swapped out.

It's a good working radio, but it's been giving me an annoying problem ever since I reprogrammed it this afternoon for GMRS.

When the radio receives a signal (so far I've only tested this on GMRS), there is a loud burst of static that the radio spits out after the other radio has finished transmitting. This sound lasts for a good second, and the receive LED stays on during this time, as if the radio is still receiving a signal.

It did this when I keyed up both my TK-380 portables. It also happened following the feedback signal from a repeater I keyed up.

I've never had this issue with any of my other radios, and this radio was working fine up until the time I reprogrammed it, so I'm sure it's a programming issue. Does anyone know how I can fix it? I'll continue investigating while I wait for a reply.

Thanks in advance!

One of two things are taking place, maybe both. First question is the receiver tone squelched? My guess is it is set for carrier squelch from what your describing. Not having one of these radios ever in my possession, I can't say for sure, but in many of these radios, the mic hang up clip needs to be grounded or the button on the back side of the mic needs to be depressed to make the receiver go into tone squelch.

Second question is have you tried to tighten up the squelch? It sounds like the squelch is set way too loose and is taking a long time to close the audio down after a signal drops from the receiver.

Hi Jim,

I just considered squelch a few minutes before you replied. No, I do not have any tones set, at least not for my GMRS channels.

I do have my squelch set low. It's at 1. I'll try messing with that setting tomorrow.
