Re: [Repeater-Builder] the mobile micor

I have seen a Micor mobile hooked to an Astron power supply that went whacko and for an indeterminate period was running 16 volts from the p.s. with no apparent damage to the Micor.  On the other hand, I saw one in a police car in which the voltage regulator in the alternator went whacko and fried everything (battery, bulbs, radio, electronic siren) when the alternator voltage went to 25 volts at high engine r.p.m.'s. during a rather long pursuit.

any one know what the max dc volts a micor can take before it cooks?
I have a motorola cabinet not sure from what but it has a power supply in it
that is capable of out putting 13.1 to 16.3 v at 36a. I just want to be sure
that I won't cook the repeater and the control micor mobile. yes I will have
two micors one will be a simplex control radio the other will be duplexed
for the repeater I will also have a tmd 700 for a frequency agile link
radio. plus a rc 210 all runing off this power supply.
    

If you are running mobiles as a repeater system plus other radios that expect
13.8v I'd set it to 13.8v and use heavy wire to a power distribution buss that
feeds the radios, but in any case no more than 14.0
