Hello all. New here to the board that I didn't even know existed until I posted a "kenwood" post on batlabs and got my hands slapped. I've been using Kenwoods for almost 10 years and prefer them to any other.
Firstly, just got my 730 and 830 today for my dual band setup. I still need several parts to get this going and they are:
kch-4 alpha head with aux key tabs and bracket
kmb-5 deck mount bracket
dyna mic
control cable (12-18 in) to connect UHF deck to VHF deck.
2 power caables forr med power decks. dont need to be long, just mainly looking for the plugs. 12 in wire is fine.
channel upgrade kit
Next, the problems. UHF deck powers up fine. Has KRK-2 connected to it. VHF won't fire, has KRK-4DB on it. The radios came from different places, weren't connected together. Does the VHF deck need to be connected to the other deck to turn on? I also tried the krk-2 on the VHF, wouldn't turn on. Then, put the head directly onto the deck, still wouldn't turn on. Wondering if it's ign sense... how can I tell? Don't want it that way, so how can I fix? Was reading up on w101 and w102..... chips?..... What are these and where are they located?
So far just the VHF power problem, minus not being able to read the UHF with Kenwood factory software.... but i think that's the computer I'm using. And also needing the above parts... have some Motorola Spectra parts to trade. E-mail to rwo978@hotmail.com or PM with answers.
Several 30 mobile series questions and wanted

I have a used but excellent KCH-4 (PM if interested). I believe a 90 series mounting bracket will fit the head (will have to check sizes).
The mic is still available from Kenwood service parts, as are the power cables.
The channel upgrade kit is no longer available, but you can use (3) digi-key EEPROMS, part #AT24C16A-10PI-1.8-ND (16K serial RAM)
The radio to radio cable is identical to the 90-series radio to radio cable except for the weather-boot style (which shouldn't be an issue unless you are mounting in a wet location).
You will need FAB or FAD firmware for dual radio (one is dual head, one is dual radio and I'll have to check on which is which).
There is a modification chart for dual head and dual radio setups. I believe it was necessary to run a jumper between solder pads to enable the "slave" radio to turn on in conjunction with the master (and also to tie the CPU reset lines together). I should have a copy at work and I'll see if I can scan it for you. It's a little more complicated than just plugging the two radios together, but it's not bad if you have the technical service bulletin.
