[Motorola] Was Encoder, Now MICOR and Channel Elements....

I recommend good Torx bits, or you'll strip them out. Check out Wiha Tools
(google it). Good stuff, not terribly unreasonable on price.

Those Torx security screws are no problem, go buy a bit kit from any tool
dealer, done...

I bought a set of security bits years ago from a company that i used to get
a catalog from, don't recall the name now, but it cost me maybe $20 for a
set.

Howdy Dan,

    We in MARS can use pretty much any piece of Ham or commercial 

gear that will tune into the bands. I know what you mean about money 

pit, had a Micor working as a repeater for 10 years. About every 4 months, 

there was always some part that failed and took it down for a few days at a
time. 

     I can even build a Ramsey kit if need be. Now in 2013 when MARS
exemption 

to NTIA Federal Frequencies bandwidth reqs (See the red book of NTIA for
details),

we will have to have equipment that can do the 12.5 instead of 25 KHz step
and 

3.5 instead of 5 KHz width on VHF. 

    Some of the new Yaesu and Kenwood rigs will do the narrow splits and
transmission, BUT

have gone back to having to do a hardware modification to do MARS/CAP
operations. And 

many also have added those Torx security screws to the cases so you can't
just 'open them up'

and they charge about $250 to do the mod for you... 

    I used to really love building repeaters from GE MASTR II's But those
are rare finds these days...

MICORs were great radios in their day, but whatever treasure trove you have
just might be an achor around your neck! If you're rebuilding one for the
thrill of it, that's cool but if you want to do a whole fleet of them, I
think you're putting a LOT of resources into a money pit. You might almost
do better cannabilizing the RF amps out of the MICORs, recycle the rest of
the hardware, buying modern low power exciters, and ending up with modern
high power radios. Just my $0.02. Oh yeah, not sure if MARS rges let you do
all that, but that'd be a fun ham club project.

Sad but true, one of the MARS members in Ohio confirmed CEH is gone, having
sold all their components to ICM, due to cost of stuff.... Oh Well... But
now i have info... and no I guess reading up on these military monster
Micors they are actually 30 channels and do a simplex or duplex switching to
do '60' channels. (IE 1 is duplexed (one tx, one rx frequency) Channel two
is simplexed (TX/RX on same frequency from channel 1). I am not sure how
they would do this one either, since the frequency conversion for TX and RX
is different looking at the math, I don't quite get it...

Big heavy drawer units, about twice the size of commercial micors I have had
in the past, the receivers are 142-153 MHz already, and most had first
frequency of 148.650 currently in the MARS pool, formerly in the USAF pool.
None have the heads, but all have the cables, power cords and are ALL 100
Watt units. Mounting instructions deal with mounting them inside of mobile
comm shelters. No mention of operating in jeeps, cars etc... Wondering if I
could use a controller, one radio for transmitter the other for receiver
since I always seem to have problems once I add hot power to both TX/RX
during conversion.... 

TNX though... I guess I will get them from ICM/BoMar...anyone have their
contact info???

Then I would have to agree, as I believe all of the places like "Channel 
Element Headquarters" are no longer in business.
