Determining QT/DQT from PL/DPL

[Methus]

Okay, I am still very new to all this, so please excuse me if this sounds like one of those "duh" questions.

I have a TK-2312, and the necessary software and cabling. What I'm a bit confused about is the QT/DQT section when programming in frequencies. The PL's are fairly easy, as they're at the top of the drop-down list and I understand they're the exact same (PL-to-QT). However, it's the DPL/DQT's I'm confused about. There seems to be two sets of DQT's? They're ones that stop with an 'N' and the ones closer to the bottom end with an 'l'.

My question is this: say you have a DPL of 054; how do you determine whether to use D054N or D054l as the DQT? Or would one go on TX and the other RX?

Use the "N" version and run a test. If the Kenwood appears not to be unmuting on good freq and tone, try the "I" version.

The difference is polarity (i.e., what is a digital "1" and what is a digital "0"); there is no industry standard.

I'm guessing the suffix N is for normal, and the suffix I stands for inverted.

I'd go with "N"

Ok, I programmed three channels for a frequency that uses the before-mentioned tone. I set one to none as a control, and the others with the N and the l, respectively.

The control worked fine, no surprise. I switched over to the N channel and I was receiving the signal and it was being unmuted, good news. The l channel was receiving, but not being unmuted.

Thanks for the suggestion you two.

I know this is ancient, but I have to thank everyone for this site! I have been struggling for hours trying to program a "new to me" Kenwood TK-840(N) with a DCS (DQT). This was the final piece of the puzzle!
