Eric,
Could you please give us a little more information please.
What radio are you presently using for your UHF repeater? Does it have a preamp
and if so what type? How much power out of the repeater transmitter do you
presently have?
Also what are you currently using for a duplexer and
Some time ago I purchased a fan control board kit on eBay. Now that I want to
put it together, I find that I don't have a schematic or parts list to help me
sort out what goes where on the board. The PCB is about 1 1/8 x 2 3/4, and
the circuit uses an LM393 dual comparator. I've found a lot
I know of a group that did exactly what you are talking about with Mitrek
boards about 10-15 years ago. It was a HELLUVA lot off work to get it right,
and a pain to work on when it failed.
Get a power amp meant to do the job, or stick with 40-50 watts (no one will
notice the difference anyway)!

Rule of thumb is that you need at least 10 times the distance of

of vertical spacing is equal to 150 feet of horizontal spacing.

I'm looking for preamps for GE Delta-S radios, both highband and UHF. Can
use a few of each. Yes, I know I could graft in a different preamp, but I'm
looking for original parts.

A word of caution - your results may vary from the next guy's installation.
There are a lot of variables. Receiver front end rejection being one of
them.

Ok, so that calls for a mast of at least 30 feet to put the RX antenna on
top and the TX
My first UHF repeater used exactly this setup. I cut off the PA assy from the
rest of the radio and milled the fins off of the casting. This was then
attached to a large heatsink and rack mounted. I used it for at least 5 years
and then sold it to amother Ham who donated it to the Wheaton

I recenty received a 100w Motorola MSR-2000. It is now on 159/151 split. It has
a set of small square cans for duplexers in the bottom. Now I am more of a
Mastr II and Kenwood guy and don't know much about Motorola repeaters. Can I
put this beast on 2M?
Thanks!
I have a good used one here. If anyone is interested, please reply direct.

Hi Norm,
The internal duplexers are commercial wide split and
won't do the classic Amateur 600KHz repeater offset... so
they go away (you sell or trade them off to a commercial
radio system operator like me as an example).
The repeater will tune right up into the ham bands but you
should
I'd use an NHRC-4, at those prices you can afford a spare. With a 4PDT
relay and a Com-Spec ST-809B you can even have it as a remote control
hot-swap spare.
One of the repeater groups in my area is prepping a TKR-750
for installation. I did the checkout and setup of the
machine, and my opinions are mixed. The radio (the TKR-850
is the very similar UHF model) appears to be fairly well-made,
but I have some doubts about it being
The Hustler 220 Antenna is a great dollar value for both
repeater and home station operation.

Hi Skipp,
Good to hear you. All of what you have said is true about the version 1.0
repeater and the version 2.0 has all of the below complaints addressed and
has been a very reliable repeater. The RKR repeater is a good repeater but
seem to melt down at the rated 25watts for 100% duty cycle,
.

Mike,
If your repeater application does not absolutely require an omnidirectional
antenna, you might consider the Astron Wireless model 220-4H Yagi antenna,
info attached. A modest-gain Yagi has a better vertical pattern than most
fiberglass omni antennas, and is ideal where the repeater site is
and have seen little discussion on the reflector. Any help is
appreciated.

Kind of a waste for a 1 repeater/no links system - the FF-800 is a 5-port
controller.
NHRC (http://www.nhrc.net) makes a 1 port controller (NHRC-micro) that's
small enough to fit inside

I'm using Comet CX-333s (triband - 2/220/440) on 2 fairly low-level (~700'
