Hi to All,

?

We have many Motorola MSR2000 VHF, UHF and cross-Band RX VHF TX UHF station still on the air and they have a common Molex plug intermittence on the audio and control card’s.

?

Every couple of years’ they start to have intermittent problem’s and we have to go to the site and pull out an in a few time all the card and the station return to normal use

?

I know it is very common in commercial use to pull out all the cars and use an external controller like a CSI or Zetron, that could be applied to certain station like our cross-band one.

?

But some are a voting station connected to a Motorola Spectra-Tac and some are RF Link I would need 3 Zetron to do it…

?

Si I am looking to keep using the original Motorola card’s but find a fix to the contact problem.

?

Doe’s anybody ever found a fix to this common problem?

?

For info here are the card’s we use:

?

Line Driver (to drive audio to the RF link)

?

Station Control (to control the station)

?

Squelch-Gate (for local repeat operation)

?

Original Motorola Morse ID

?

PL Card for RX and TX CTCSS

?

R1 Audio (the Squelch control the audio going to the RF Link)

?

Time-Out Timer

?

?

Any suggestion would appreciated.

?

Best 73 to All.
