Micom 500 is a Mobat Micom 2 HF SSB radio packaged with a 500 watt
amplifier and AC power supply. Most folks think of Micom radios as
being Motorola products. Actually they are made in Isreal by Mobat, now
a part of Tadiran. Motorola has an agreement to distribute the line.
the summer of 2007, a number of the Micom 500E radios were auctioned on
eBay. These pages are an effort to document the efforts to understand
these units and make them operational. The photo above shows what a
complete unit would look like.
As auctioned, the
units did not
include the control head, control head cable, microphone, or the rectangluar black plate to
which the control head was mounted. The photo to the right shows a unit
The unit I
received has part of a paper tag on the top that says "U.S. Department
of State" The square green tag on the upper right corner says "This
medium is UNCLASSIFIED. U.S. Government Property"
unit appeared to have been unused, the inside was absolutely spotless
with no signs of dust. Mine also had an intact seal from its last trip
to the State Department's commo shop - something like "serviced by
cleared American Citizen." Other buyers reported their units were
similarly spotless. At least one buyer has powered his 500E up with the
cable and control head from his Micom 2E and reports that his unit
photo above is another view of a complete unit. A
complete Micom 500E would have the chassis, plus a control head mounted
to a rectangular black plate that includes an internal speaker. In
addition, there would he a
remote head cable coiled up and tucked inside the chassis.

are two different versions of the Micom 500E hardware - one version
with an SG-500 amplifier, and a later version with a Tadiran 500W
amplifier. The units sold on eBay all appear to have the SGC SG-500

with an SGC amplifier is here.
Parts are Needed?As
received from the seller, the 500E needs the following to be
Head. A Micom 2TS or 2E control head. FLN2418
Control Head to Radio Cable.
A remote cable. The part number for the cable is
This cable is also used by
Motorola for their MCS2000
line of commercial mobile radios. Check ebay for these, as they do show
up from time to time.
The same cable comes in
different lengths with these part numbers:
HKN6111B - 10 Foot (3m) Control
HKN6112B - 17 Foot (5m) Control Head Cable
- 22 Foot (7m) Control Head Cable
HKN6118B - 40 Foot (12m)
Control Head Cable
HKN612B has been
confirmed to work, and is the same cable as supplied with some Micom 2E
installations. This is known to work, as the number has been taken from a working Micom-2 trunk mount installation.
If you call up a dealer and ask for the part number for this cable, you will be told HKN6098A. This is probably
just a Micom / Mobat specific part number for the same cable as one of the
MCS200 part number cables listed above.
Several Motorola part numbers should work including HSN4027A
newer version HSN4038A. These speakers
were used by
Motorola in trunk mount installations of the MCS2000 radio and should
have the correct connector to mate with the speaker plug on the remote
I have a HSN4038A acquired off ebay, and
it has the correct connector to mate with the HKN6112B remote
head cable. As HSN4038A is specified as a speaker for a trunk mount MCS2000 it ought to work just fine.
Motorola part number FMN1615A.
Motorola's on-line parts system shows this part number as Micom 2
microphone HMN3596A appears to be part for part identical with the
FMN1615A, based on an examination of several mics of both types. I
have had a definite report that when tested side by side on a micom 2,
the FMN1615A and HMN3596A appear to peform equally. This is no surprise
since both mics appear to have the exact same" innards."
HMN3596A is a more common Motorola mic, and can often be found on ebay.
FKN4617A. When you order the RSS programming software, it may be
possible to order a programming kit that includes this cable.
are two dealers you need to know about:
Mobat-USA is the
distributor for the Micom line, which is actually made in Isreal. Contact Mobat-USA for repair information.
is a dealer with a significant focus on Micom radios. Talk to Dave
Carothers at Royal. I have been talking to him at the 500E, so he is up
on this unit which appears to be somewhat less common. I purchased my
control head and programming software from Dave, he is knowledge and
helpful and does not object to small orders.
ever dealer you talk to, make certain they understand that you are
talking about the 500E and not the apparently more common RM500.
