TK690/TK790 Programming issue

[tmoore425]

I recently purchased a Kenwood TK-790 and TK-690H, with the advanced control head.
kenwood tk790 tk690 dual band vhf low band 2 meter 10 meter radio

Once I got a chance to program it, I noticed that there was UHF frequencies in the lowband radio. This seemed odd so I ended up saving the original programming that was on the radio. Once the radio was programmed I went to test it with my other radios. The VHF portion of the radio was receiving fine and acting appropriately but when test the lowband it was not giving me any feed back what so ever. When programing it did given the error stating the at I need to check the model number.

Has anyone ever experienced this before? Or is the lowband portion of this radio completely screwed up and dead?

The other thing I couldn't get working was the external speaker. I am assuming I just didn't have the jumpers in the right spots. The back of the radios has the 9 pin connector and the control head has the 12 pin. I know that the speaker is suppose to go to 10 and 11 on the head and that on the back of the radio it pin 2 and 6.

If you have any suggestions on how or if either of these issues could be fix you help would be greatly appreciated.

Thank you,
Tyler

You saved your original programming as you got it. The right thing to do in any case even though it may be wrong.

The one thing about Kenwoods is that you can force the wrong programming in the radio and it sounds like this is the case. Your radio thinks it's a VHF/UHF which its not. I would try and build a simple archive from scratch that is both VHF hi/lo and write it to the radio. It will come up model mismatch, but hit OK to proceed and it will load the correct parameters. Then test to see if things are working right. Now you can sweat and fill out the programming as needed.

If you are going to use the speaker off the control head, yes pins 10 and 11 is want you want to use. You will need the 9 pin connector on the back of radio one with a jumper wire between pins 3 and 6. This will route audio to the control head.

It ended up being that the seller mislabeled the radio. It was a type 3 instead of the type 1. I did get to pick up a type 1 today. When I went to switch the remote head plug in I noticed a jumper wirer between the colored wires and the white. It is the solider point behind the color plug in and pin 4 on the white plug in.
What is this jumper for? Should I just remove it? I can supply a picture once I get on my computer if that would be helpful.
