Kenwood TK 3312

Hi,

I recently bought the UHF kenwood TK 3312 portable. Currently i am trying to figure out how to set up the 2 tone function correctly. I have 3 different sets of tones i need to place in to my radio. I went under the 2 tone function menu and placed the tone numbers in the 2 tone decode 1, 2 and 3. I then went on to the programming screen where freq are placed and under optional signaling chose the desired freq with the correct tone format. I tested the tones out and can only get tone 1 to work but cannot get tone 2 and 3 to work. Any opinions on this, or is the radio only a one 2 tone decoder.

Thanks
Cody

The 3312 will decode 2 "tone pairs" on each of the 3 decode tabs (2-tone 1,2,3) for a total of 6. It can only decode 2 pairs {per channel/frequency/talkgroup} reliably due to the scan function (see other threads). Higher end radios can decode more pairs per channel--3180 will do 4.

I have tried to place the 2 tones on different zones and different frequencies. Some of my frequencies have the same pl tones. That shouldn't matter, would it? I would just like to add 2 different sets of tones. Tone 1 decode I have the 2 tone formats. 1 sec, 3 sec. Tone 2 I have the correct numbers for the tone format. Does itmatter if it copies tone 1 format (a-b) or does it have to be (b-c).

It may be simpler to post/PM your frequencies and tones or .dat file and I can send a screen shot of how I would set it up.

Different programming zones will not affect the decoding of 2-tone signaling.

Each channel can decode up to 2 tone pairs (or long single tones) in row 1 & 2 on the decode tabs in Edit-->2-tone. The easiest format would be A-B and C-D with the corresponding tones put in the boxes below them.

Each channel/frequency would use different Optional Signaling (2-tone 1, 2, or 3) unless the pairs were identical (tone and order). This allows 3 channels to use 2-tone decode.

In your case, frequency A would use 2-tone 1 and frequency B would use 2-tone 2 for the signaling. Be sure to use the different decode tabs if the tones are different.

Ok, I print Screened all the necessary screens on the software. Let me Know what you see is wrong.

Thank you,

Everything should work in 1 zone unless you want to separate them for organization.

Since CAM EMS has 2 "tone pairs", they should go on the same decode tab (2-tone 2) as A-B in row 1 and C-D in row 2--see below.

The way you had it set up, it would only alert if the specific tone pair was heard instead of either. Also, scanning will skip alerting if the first tone is missed due to scan time. For info on the choices at the top of the Zone Information window, type F1 while it is highlighted.
