I have been operating a 10 meter FM repeater on 29.56/29/66 for the last 15+
years
in Minnesota. It was a split site repeater with the repeater IDer/at the
receive site and
a cross-connect to a 2 meter repeater where a full function 2 port repeater
controller
provided the ID and control. .
Why can the same ID not be used for both
as long as it is part of the same system?

I want to thank all of you that responed to my quary about puting up a
10 meter repeater. Your information is going to be a big help in
decideing whether to put up a repeater, also if we do put one on the
air, this info will put us in the right direction.

Hello all,
I have acquired an SCR500 Receiver in the VHF range. My ultimate goal
is to connect this to an ACC RC96 controller, as a control receiver.
However I do not have a manual for the receiverdoes anyone have one
that they can email me.
It would be greatly appreciated.
Thanks
Has anybody every tuned one of these down to ham frequencies?
Does anybody have (or know where I can find) a manual and programming
cable?
Thanks in advance

Phil Salas, AD5X, is a tremendous person and an excellent ham. I have known
Phil since he hired into TI as a new EE in the early 70's. He stayed there a
few years and then went away and up on his career and made me jealous when he
retired many years before me!

Paul,
What was your goal for the repeater? Was it intended to be useful for distant
users during band openings, or for locals when the band was dead?
Using a horizontal dipole on the receiver punished mobiles running vertical
whips by as much as 20 - 25 dB, and have coverage nulls off the ends
The AD5X web page is well worth a visit if you've not
seen it before.

You are assuming that all users will be coming into the first crossband
equipment, but in reality, there may be users that come in on the
crosslink receiver, therefore, no ID would ever happen on that user at
the main transmitter. Also, if the crosslink were run in carrier
squelch, and noise

Thanks for the info -- I'd love a copy of the manual -- tell me how much and I
can paypal or whatever you like.
Thanks very much again!

Hi,
Squelched discriminator is a paradox of terms! Most of the time the
squelch function is derived from the noise seen at the discriminator.
I suspect you really mean either filtered (deemphasized) or
unfiltered gated audio and/or COS. On a Kenwood redio I had a similar
requirement. I used
You're assuming they will. If it is guarded (and ANY control link should
be guarded and not running CSQ), they should not be coming in the
control link. But, your point is well taken.
I guess someone can break into the site and key your TX, too. It's
really the same difference as if they hack
No, I am not certain. I had someone program the radios for ham freq.
That is kind of what I was wondering. The manual shows the 8 channel
pin 8 is COR and the 16 channel pin 8 is programmable. I don't have,
or haven't found documentation for the RSS software. Is there a option
in the program that

It is similar to a DB224, but has a smaller diameter mast, with
thicker wall, and the harness is interior to the mast.
The dipoles are fed through the interior of the bracket that holds the

I was looking at the same general idea for combining a 2m repeater with 2
simplex radios (APRS and WinLink) on the same antenna - it MIGHT have worked
- but I got the repeater on 440 which eliminated a lot of problems trying to
work 4 frequencies within a 1mhz span.

Hi,
The length of cable for low split 138-145MHz C2037 multi coupler is:
4 between reject and T FFF UG28A/U
4 between first pass and T FFF UG28A/U
12 between feed through T and Antenna T
24 between the other pass
The length of cable is only for cable without connectors. Use
Ok Dave,
I'm still stumped a bit why you need gated audio. Is there not a

the time?
