Repeater-builder received an interesting article request...
Too many of the folks that have been doing it for a while
forget that we all had to start somewhere.
Everybody seems to know how to install Heliax connectors but
us newbies. And sometime the newbies don't know who to ask.
And

Al, I would program the Z38A the way you have with one change. I am sure the
system ID should be the same as the user ID, so instead of assigning the system
ID to an unused user ID, I would use the user ID as the system ID. Just enter
the user number for the tone you are using for normal user
With RingFlare connectors it is basically the same procedure
for 1/2 and 7/8, DIN and N.
The main thing is to strip the correct amount of insulation off and the
center conductor needs to be the proper length. Although when you first
look at the instruction sheet it is confusing, once you read
Yes Mike...
I'll put my hand up if this article I have here is of any use.
It's an old yellowed original bulletin # 37383C by Andrew Communication,
with explicit instructions on preparing fitting N connectors to
LDF4-50A Heliax.
I did a quick search on their web page, but it didn't come up.
It
sounds like you talked to the same person I talked to and I was doing a
business system.

Last week we installed one Kenwood TKR 750 (Type 2)in our nearby
airport for the use of the security organisation.
The Tx is in 143.95 and Rx is in 148.950. The antenna is Diamond F22
without any trimming (144Mhz). The Repeater delivers 20Watt into the
duplexer of local manufacture and
In a nutshell, yes they're great. The documentation you get with the
station is wonderful, too. We have been using them here in Missouri for two
years now and not any problems with them. They are known for their low
current consumption. If they don't make an amplifier that suits your needs,
Does anyone use a transmitter identification system on your repeaters to
id the incoming signals?

I have one also.
I need a manual and programming info.
It has a M3-7603-5 chip in it. I think it it contains the callsign and
timing info.

One suggestion is to go to a simple ground plane antenna, and mount it upside
down on top of your terminal building. The gain in an antenna will concentrate
the radiation out on the horizon, which is not what you want. The upside down
ground plane with no gain might be your best bet to have
A quick answer Peter...
Buy an antenna power splitter similar to the type sold by M-Squared
Antennas in California. Place the splitter into the antenna system
and run a second antenna inside the building.

Make sure the duplexer is connected to the correct ports of the repeater.
The MSR-2000 to external repeater article on the
www.radiowrench.com/sonic page has a scanned image of the
Squelch Gate Module included.
The instructions also mention how a resistor in series with
the output is removed and the controller input/output audio
paths are simply inserted in place
Hi,
I have several RCA UHF repeaters available for sale..cheap. These are
working units removed from commercial service in 2005. Most have a
Zetron controller installed in the cabinet; those can be had as an
option with the repeater. Service literature is also available.
These machines are old

Hi, Jim... I'm trying to do the same thing, to cover the interior of a

We have done numerous installation of small in-building repeaters in high rise

I wonder if the CWID-70 is a later version of the CWID-50 made by Control

Bernie,
Yes, I use MDC1200 coding on every portable and mobile radio in my fleet.
For convenience, I use the last four digits of the serial number as its ID
number. All radios use pre-ID with a short beep to let the user know when
to start speaking.
Although I have a printer interface on the ID
get yourself some of the hard-line that has holes in the shield to let some RF
out and install it in your building. what is what it is made for.
