• 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.

To cross band the two radios what do I need? Can you program all 160 channels in each radio and cross band whichever two frequencies you want to? I can't find much info on the KRK-4DB.

Thanks for help I can get!

You need one each TK-690, TK-790, or TK-890 plus one of the dual-band kits (KRK-7DB or KRK-8DBH). In the programming, there is a list of repeater pairs that you program into the radios.

I believe the KRK-4DB is for the TK-x30 series of radios.

So there is no way to hook them up back to back through the DB25 connectors? I was hoping to do something similar I had with two Motorola GM300's. You could select any channel at any time, no pre-set repeater pairs.

It may be possible to create a repeater by connecting two TK-x90s through the accessory port, but the KRK-7DB or KRK-8DBH is the Kenwood way of doing it. Either of those kits is intended for turning a pair of x90's into a dual-band radio. The cross-band repeater function is an additional feature of the dual-band kits.

For whatever it's worth, there's a fairly active Yahoo Group for the Kenwood TK-x90 at:

Kenwood-TK-30-90-Series-Mobiles : Kenwood-TK-30-90-Series-Mobiles

It is very easy to do using the accessory port. You can even use a RIB if you want to, and it functions flawlessly.

Maybe you meant a RICK. 'sOK, I brain poof all the time now. I hook TK-X180s back to back quite often through the acc connectors.Works great! The problem with the TK-X90 is the receive COR/TOR logic (high) is bass-akwards from the PTT input (low) and there is no way to change this. You need to provide a level converter somehow (transistor, relay or whatever).

Other than padding down receive audio to mic input, Kenwood radios can be wired together via the acc connector (with the logic snafu taken into consideration),

Motorolas are even easier. Down and dirty is just wires radio to radio. If you want fancy, get a RIB, wait I mean a RICK.

I have joined the Yahoo Groups. Hopefully I can find a schematic to build a RICK. The time I did it with Motorolas, it was almost plug and play with the directions I had.
