Yes, thanks Mike - I already scanned through that - but that is for
duplexers. I am looking for the same thing but for the entire tx rx
product line if it exists..dan n2aym

Some of the numbers that TX RX used were one-of-a-kind. I remember calling
them about a combiner they built for a company I worked for. They had all the
records of when it was built, who it was built for, and all the specifications.
There record keeping was great, they could find the document
I think I can provide a scan of model numbers if you can wait till later
today when i get my honey do list done. I have a complete txrx catalog with
all that information in it.

You can easily figure out the connections to the Mitrek test sockets by
examining the Mitrek Super Consolette test meter circuit here:
www.repeater-builder.com/motorola/test-sets/hln4138a-mitrek-consolette-mete
ring-kit.pdf
All you need is a meter with a 50 uA movement and a 17,500 ohm resistor.
According to another source, the LBI-4100 is not the one I need, but
the LBI-4938C is.

Randy,
The same information is covered in LBI-4938C, in the Ericsson format, here:
www.repeater-builder.com/ge/lbi-library/lbi-4938c.pdf
I found this LBI by using Google to search for 4EF4A3 and found several
sources. This LBI is intended to print in landscape orientation on 11 by 17
inch
It's the same manual. When Ericsson took over GE's product line, many of
the LBIs were re-issued in a uniform 11 by 17 inch format. Unfortunately,
newer is not always better. Some of Ericsson's LBIs do not contain all of
the information and/or details found in the older GE versions. Also,

My 2 friends just linked their 440 machines together using an Alinco
DR-235T at each end for the link. They did find that there is a delay
in time in which the decoder takes to decode and release. They are
going to fix this by using Audio Delay Modules in the controllers at
each end of the link.

Let's see what is wrong with my statement.
The repeater controller keys up the link radio via the PTT. The Audio
Delay Board places a one second delay on the audio being sent to the
link radio. This allows the 2 Alinco radios on either side of the link
to key up and the PL encode/decode

One other thing to consider.
If one user is on repeater A and the other user being talked with is
on the other repeater, you have a 2 second delay in turnover between the two.
As I said, your users are gonna hate it.

Ken,
TIA/EIA-603-C, the international standard for Land Mobile Radio performance,
states that CTCSS decoder response times may vary between 224 milliseconds
at 67.0 Hz to no more than 150 milliseconds at 100.0 Hz and above.
I have measured response times of 80 milliseconds in some radios to
Your original comment was:

A delay board will help fix both problems. The only question is how
much delay needs to be put into the system to make it work acceptably

I'm curious if you're talking mechanical or something else? Except
for a funky MSF5000 I've been beating on (which takes a good 900 ms
to decode 1Z), I've never seen performance as bad as you point out in
an electronic type decoder. Mechanical, sure.
For example, I have a reedless Mitrek
Like I said, IMHO you're applying a band aid instead of fixing the
root problem. Butto each his own :-)
Are you going to use COS from the receiver to gate the audio in/out
of the delay board?

I haven't figured out exactly what Pin #1 SQC Squelch Signal Output
lead characteristics of the Alinco DR-235T is. This is probably the COS
that I will use from the receiver. I would like it to be a AND PL+COS
output, but it probably is only PL decode out. We are going to

My measurements were made on an Alinco DR-605T radio which, given the known
deficiencies of the brand, may be unrepresentative of the state of the art.
The TIA Standard 603 is dated December 2004, so it is likely designed to
have rather liberal limits on decoder responses. I agree that modern DSP

Hi Joe,
The delay board we are going to be using is adjustable
for 64, 128, 256, 512 or 1024 milliseconds of delay. (NHRC-DAD board).
That delay board uses the MX609 Delta Modulation CODEC, a device with a S/N
ratio of 30-35 dB (at the highest sampling rate; varies with frequency)
In response to my earlier posting on the RB few quarries are there,
hence I wish give the following for further thought:
The antenna is CELWAVE PD340-TP2 with 4 Separate folded dipoles on a
big aluminum pipe mast. The connecting harness is routed through the
pipe mast. This particular antenna

You would need to modify the cable harness... else the modified
