A 240 VAC muffin fan run on 120 VAC is best.
Second best is a 120 VAC.
Third, 12 VDC run from a separate supply.
Fourth, 12 VDC run fr

Our repeater group is in dire need of a weatherproof outdoor cabinet for
our rebuilt repeater equipment. What I'm looking for would need to
either have 19" rack mounts installed, or have the ability to
accommodate 19" mounts. Heating/Cooling is also a concern, but not a
requirement (though

With proper filtering the 12 volt fans would be fine. I have two 4" 12 VDC fans on my PA and have no audio issues at all. They are noisy as all get out in the repeater room, but cannot be detected on the repeater.

Thanks Skipp and Marv. I have a "Spectra Tac Line Driver Equalizer"

is the Spectra Tac manual for these.

then 120v AC fans are usable. If you are going to use th

The radio doesn't care, but if you're going to switch the fans with PTT or
thermally, it'll be easier with 12 V. Al
I would go with the 120. 12volt fans have a bad habit of dirtying the
DC voltage which can ocasionally be heard in the repeaters audio.

Which fan would be better on the GE MastrII, and Motorola Micor

Skipp,
In the Repeater Builder shop, we commonly use the HP 8920A service
monitor for measuring bench sensitivity. It has the digital meter as
you speak unfavorably of. We have found that the averaging of this
function is adjustable. Making the averaging value 12 makes the thing
work like
There was both a factory option and a field modification kit that
allowed conventional Motorola Micor stations to be used in SpectraTac
systems.
First, a SpectraTac encoder card was added in the repeater card cage to
generate the status tone that allowed the "in-cabinet" (repeater)
receiver
Thank you Kevin..!
And I thought I was the only one who thought 12 dB
Sinad was noisy. So noisy that digital number meter
measuring is (in my opinion) worthless.
cheers,
skipp

If you need a Spectra Tac type operation, there are
modules (for the card-cage/backplane), which serve
up the proper tone encoding functions. Most often
you will see a special version of the line driver
module and a "spectra tac encoder" module.
Motorola also had an earlier A-B tone voting
Does a Micor base receiver, unified chassis, have any capability for
generating a voting tone? The "Control and Applications" manual does
not make any mention of any cards that would do this.
