Spectra Issue

[countywacker]

Hello i have A VHF Dual head A9 spectra in one of the ambulances that i take care of. The problem is that when someone is talking on the mic in the rear of the ambulance it will start unkeying and keying back up cuting out there transmission also resending out the mdc1200 ID. I was told this may be a software fix poss something with the time out timer. I could not find nothing on here anyone have any ideas?

In case anyone is wondering, from his thread on batlabs he said he already tried changing mics and the head itself.


I have no experience with a dual dead setup so I'll bow out now

I dont have a "This is the problem" answer for ya, but you can probably stop looking at the time out timer. On every radio Ive ever used, once the TOT expires, the radio will not re-key until you release the PTT and try again.

I suppose you could try reseating the control cable on the radio end. Or if you have another cable, you can swap it out.

What wattage are you running? Is it possible that you are getting enough RF power into the control cable that its causing this problem? Does the control head flicker or do anything strange when this happens?

The radio is running at almost max so i dont belive its a wattage problem. No problems with the head either. The control cable is the last option if i have to run a new one were juSt gona replace the wole radio with a PM1500 since were gona need narrowband in a few years.
