• To anyone looking to acquire commercial radio programming software:

    Please do not make requests for copies of radio programming software which is sold (or was sold) by the manufacturer for any monetary value. All requests will be deleted and a forum infraction issued. Making a request such as this is attempting to engage in software piracy and this forum cannot be involved or associated with this activity. The same goes for any private transaction via Private Message. Even if you attempt to engage in this activity in PM's we will still enforce the forum rules. Your PM's are not private and the administration has the right to read them if there's a hint to criminal activity.

    If you are having trouble legally obtaining software please state so. We do not want any hurt feelings when your vague post is mistaken for a free request. It is YOUR responsibility to properly word your request.

    To obtain Motorola software see the Sticky in the Motorola forum.

    The various other vendors often permit their dealers to sell the software online (i.e., Kenwood). Please use Google or some other search engine to find a dealer that sells the software. Typically each series or individual radio requires its own software package. Often the Kenwood software is less than $100 so don't be a cheapskate; just purchase it.

    For M/A Com/Harris/GE, etc: there are two software packages that program all current and past radios. One package is for conventional programming and the other for trunked programming. The trunked package is in upwards of $2,500. The conventional package is more reasonable though is still several hundred dollars. The benefit is you do not need multiple versions for each radio (unlike Motorola).

    This is a large and very visible forum. We cannot jeopardize the ability to provide the RadioReference services by allowing this activity to occur. Please respect this.

TK-8150 Loud Burst of Static After EOT

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.
