info, mods, and tips
We have been collecting data on anything having to do
with repeaters for quite a while. Our group has worked
with many brands and models of radios. For most repeater
applications we have have found the Motorola Mitrek to be
an excellent radio. Here we try to share what we have
learned, and give you a look at other sources for more
information on all commercial conversions.
- Motorola Mitrek Repeater Mods We have several different
types of repeaters in our system, but many of us are using converted
Motorola Mitrek mobile radios. We have found them to be excellent radios
for this kind of service. Consequently, we have gathered a lot of
information on them. Check out our special
Mitrek page for more information.
- Motorola Micor Repeater ModsWe are
beginning to gather Micor information. So far we
have a Micor
conversion to 220 and help with Micor model numbers.
We also have some information on converting a low band Micor to 6
- General Electric Repeater ModsThe Mastr II
and Mastr Exec II series of GE radios has been a
favorite of many for years for conversion to ham
band repeaters. Although not many in our outfit
use them, we have been gathering info for the
rest of you to use! Try our GE page for some ideas
on using these units.
- Vertex mods
which allow external controllers to be used with
other mod sites
Amatuer Repeater Builders Home Page is
good source for conversion information. This
site's main strength is the wealth of information
on GE equipment. This info includes the MVP and
Mastr Exec series in addition to the more common
Mastr II radios.
is a Motorola only site with information about
all (or close enough!!) models the company has
- Repeater Builders Technical
Information Page is a great source for
information on repeaters. Kevin's site deals
mainly with Motorola Micor and GE Mastr II
modification, but includes a wealth of
information on all things related to repeaters.
This is also the new home of the How to Convert a Mastr II page!
No matter how you plan to put your repeater together, you
are going to need to come up with parts and equipment.
Here is some help in finding (or building) what you need.
One of the main chores is getting your repeater
coordinated. Contact your local
coordination council for details in your area. Also,
let me know of any I have missed and we'll post them
tuneup and maintenance
Here are several articles to help get that repeater up
- FM Radio Tuneup Guide,
Part 1 Contains a lot of good info to
help those of us with less than perfect test
equipment get things going.
- FM Radio Tuneup Guide,
Part 2 Even more helpful hints.
- Tuneup, Part 3
starts by looking at the bad old days, then looks
at FM omni-directional antennas, with an emphasis
on repeater duty.
- Tuneup, Part 4
continues on by looking at feedlines: good, bad,
and cheap. And the answers may surprise you. Also
a close look at connectors.
other repeater systems
Since one of the major reasons for SEITS existence is our
Linked Voice Repeater System,
it is only natural that we are curious as to other such
systems. Here is a list of other
sites built by individuals and clubs that talk about
thir repeaters, including, sometimes, their mods and
tips. The list includes both single repeaters and linked
