TK-880 PL Tones

[chevymn1964]

Hello all, I have a few TK-880 that were pulled from our old trucks, I would like to program for GMRS with local repeater capabilities, the problem that I am having is that I can't get the radios to tx a pl tone ( Encode ) I've tried the ol Off-Hook Decode trick and still nothing, I can go into test mode and select a few different tones and then it will work as should.... Any ideas out there?

I don't have KPG-49 on my computer to check the specifics, but look at the software and see if there is a section called "Extended Function". The newer softwares have this, can't remember if KPG-49 does, or if it's called something else.

If it's there, look at the "modulation line" tab/section. There may be a part that talks about MI1 (front mic), make sure "with QT/DQT" is enabled.

Again, I don't have the software in front of me, so I may be way off, but there's likely a similar setting in there. If they used these radios with a headset system, someone may have set them up to use the mic input on the rear.

I think I have KPG-89 on another computer, so if that doesn't get you going in the right direction, let me know and I'll see if I can find it.

If you can send me your codeplug file I can take a look at it and test it on my TK880 radio.

Are you a Chevy guy? Here's one of my Chevys

I use a TK880 for GMRS so I took a quick peek at the software (KPG-49D) When the radio model selected is conventional (or if one of the systems of a trunked programmed system is conventional the QT/DQT Enc is where the PL tone for transmitting is selected. In trunked mode, a PL tone isn't available. So, you'll need to ensure that your programming in the proper mode. Hope that helps

Select the Model drop down menu on the title bar and select conventional:



Once this is selected, you'll have the option to choose an ENC frequency:





I hope this helps

Did you ever get this working? I'm having the same issue and some other weird issues Like trying to tnasmit on my configured channel 1,8, 22 forces radio to channel 2. The upper channels all have some static type feedback. I've got 2 tk880-1 v2. So either both are broken the same way or my config is off somewhere I can't find.

Did they come from the same source? Maybe there's some sort of hardware hackery inside?

BTW I have KPG-49 codeplugs for TK-880-1v2.0 that were moved from being used on LTR and conventional to just conventional and the Radio Format is still set to trunking (which does trunking and conventional). CTCSS works fine on them. There are also codeplugs with both trunking and conventional channels in which the CTCSS are very likely working or I would have heard about it.

I don't think I've ever needed to change the Radio Format. It looks like it just changes the memory organization between

1. Trunking – 32 systems (32 bytes + 16 bytes per repeater) of 250 groups (16 bytes each) in 19712 bytes of free space in a new codeplug
2. Conventional – 250 groups of 250 channels (48 bytes each) in 12000 bytes of free space in a new codeplug

One other thing that going from Trunking to Conventional changes is the scan triangle icons. In trunking the triangle indicates the channel is locked out of scan, and in conventional the triangle indicates the channel is in the scan list. This used to drive me crazy, I carried both a 280 in conventional and 380 in LTR.
Now if the VP8000 would do LTR and NXDN I could stop carrying two or three radios.
