• 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.

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.

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…..
