Has anyone had experience with a UHF Visar sending an EMERGENCY signal 5 seconds after power up? I have:

A- removed ALL references to MDC.

B- Cloned from a unit with NO MDC enabled.

and all the above has had no effect?

Is this unit scared with Halloween close an all ?

Have you checked that the side buttons aren't stuck or otherwise making contact and activating the switch?

Yes. The buttons function and are not stuck. The are programmed for:

BLUE - Light
MIDDLE - Mon

Good guess.

Further info...

Five seconds after power up the unit beeps , pauses ,them sends and MDC burst five times and then goes into normal operation.

Those radios are very flaky, I had one that if you put just a little pressure on the speker the audio cut out, another display would cut out for no reason. they are a nice size radio but they are were not made with M quality

The pcb in the front cover is mounted to a rather flimsy plastic, not a die cast metal. There are some rather large SMT ICs on that board. The pcb flexes with use, but the chips being large and sturdy don't want to flex along with it. The result is the solder joints underneath the ICs are stressed and eventually crack resulting in intermittant connections.

The cost of a flat rate repair for Visars has gotten rather expensive and the repaired radio will only break again since the design flaw hasn't been corrected. A customer with a large amount of Visars will conclude that Motorola equipment is junk and take their business elsewhere.

Visars are strange radios...I have a few of them, luckily they don't get much abuse so they do not suffer common complaints I read about- other than the one problem which drove me absolutely nuts- and other models of big M port's do it too...THE FRIGGIN THING CRACKLES ON TRANSMIT!!! (to the person recieving) the official fix from motorola barely adresses the problem...has to do with grounding, shields, mechanical things touching each other...(that little metal bar behind the ptt touching the side of the innards, that funny little antenna clip coming back touching itself, the covers having way too many ground points, etc...) I really like the size of the visar, (using the thin battery and dialing in ALOT of battery save time, practical only in repeater applications where the repeater hang overcomes the off time of battery save) even compared to the "ex" series...too bad they are such a pain in the pontoons to make work good....can be done, but way too labor intensive...
