x9000 help

[nm4v]

I got lucky (I think) and got several X9000 radios cables and control heads in an auction recently. Since these are low band radios I had hoped to put them on 10 meters and 6 meters for several of the locals. My problem seems to come when assembling the parts. I hooked the cables together and immediately got a short on the 12V pos line. Upon experimenting is seems that plugging the control cable into the head creates the short. These are not the fancy heads but a clamshell head 16 ch with a AB switch for 32 channels. Could the heads not match the radios? It looks like a diode is getting hot in the head and is cracked (shorted I know). I am afraid to go any further with out knowing more. I do not have the head number handy, but it looks like the one used on a standard Syntor.

Charles,

There is a lot of X9000 information on this site:

The X9000's do not use a clamshell. You most likely have a Syntor or Syntor X.

The X9000's use the Systems 9000 head which looks the same (if it has the full keypad) as the Specta A9/Astro Spectra W9 heads.

Here is everything you will need to know about the Syntor X: (courtesy of Mike B.)

Sounds like you have the mike and the blue 6 pin connector swapped. The blue plug goes to the outside, the mike plugs into the center.

The radios are definitely x9000 units. It looks like I have the wrong cables and heads.

Thanks,

The main difference is the personality board and the common circuits board. By swapping out these two boards you may convert a Syntor X 9000 into a Syntor X or the other way around. The only thing is if someone does this to the radio, the model information label on the front of the drawer will not be correct.

Also be aware these radios have optional positive ground cables with reversed power connections. The Syntor X 9000 negative ground cable pin outs look like this:

This link also shows what the Systems 9000 control head connector pin out should look like. If your cable is for a clamshell, but it fits the front of the Syntor X 9000 radio drawer, then it is really a Syntor X or trunking Syntor X radio cable.
