KPG-89DN Advanced Setting: QT Reverse Burst Phase, Tuning Frequency

[RenoHuskerDu]

I am fine tuning the programming of my Kenwood TK-8180H K2 mobiles. Poking around in KPG Advanced Setting (screenshots below) I found some settings that are not documented in the Help that came with the software.

I think I understand Setting 1. My QT Reverse Burst Phase is set to +180°, which is the squelch tail? If I don't use QT does it still matter? Will repeaters care? I found this in search here Related 2020 thread but it does not answer my question.

For Setting 2 Tuning Frequency, again no mention in Help. It looks like tiny repeater offsets. Should I erase those and instead program desired repeater offsets in my saved repeater channels?

In that 2020 thread @mmckenna suggested I'd need to go into Engineering Mode. But these fields are not greyed out for me, you can see in the screenshots.

Those are softpots. Unless you have a service monitor, proper test cables and a service manual, leave that alone unless you want your radio to perform poorly.

Reverse burst it to eliminate tye squelch crash when you unkey. The QT circuit detects the change in phase and stops sending audio to the speaker before the signal goes away. The common phase changes are 120⁰ and 180⁰.

kayn1n32008 covered the QT burst stuff. Unless you have a specific need to change it, leave it as is. If you don't know what that specific need is, then don't touch it.

Tuning frequencies is the frequencies it uses when running in test/alignment mode. Changing those won't change the way the radio operates, however it is ONLY used when doing alignment. Again, don't mess with it.

Wish I could recall why I suggested engineering mode…..

OK guys, I'm convinced. I'll leave sleeping dogs lie, as it were. Thank you.
