MT1000 VCO Module Plugs (...or unplugging, as it were...)

Post by indigo »

OK, I will finally ask the question, often pondered, never deeply thought about though, but tonight I gave it more thought than normal... When pulling the VCO module plugs on an MT1000 (for the purposes of physically determining bandsplit, or for attempting to recover a "bombed" unit, or other purposes, each (white in color) plug has 7 (I believe) leads on it. When pulling these suckers, of course assuming there is no juice to the unit at the time, is there any possible harm that could occur by shorting any of these leads on each of the (2) plugs (i.e. inadvertantly shorting against the inner solid metal case housing) ? ? There's not a lot of clearance there - should a temporary insulator (i.e. duck tape) be affixed? Thanks gentlemen (and ladies...?), and for additional info. below is a portion of the main site's initial description for possible bad genesis (MT1000) code plug remedy:

Clearing a MT1000 (or HT600) with an Invalid Codeplug

Here is something to try if you somehow get the wrong bandsplit programmed into the radio.

When the codeplug has invalid data, it may send out a continuous tone, from the VCO module being out of lock. To defeat this, you can try a couple of things:

- First, open the radio.

- As you look into the front of the radio with the cover removed, there are 2 white plugs near the bottom of the radio. You may have to remove the RF shield to see it, depending on which model you have.

- Now, you can try the quick and simple method of just unplugging both plugs going to the VCO module.

Thanks folks...

No problem

I don't see a problem with them touching if there is no power to the radio. I used to have to fix 2 or 3 a week for the Sheriff's office and never had any problems. Just don't break the pins or the flex cable, it gets brittle with age.
