type much better than the carbon

I've seen on many auction sites folks selling pairs of ICOM commercial
radios glued together as repeaters. Often it has been IC-221S or IC-
121S units and sometimes IC-111S or IC-211S units.
My question is, does anyone here know how difficult it is to get the
signals you might need (like PTT,

The box that comes out of the ground, is this termed the A
Box? Do you think SPC (old Pacific Bell) would change that
assembly on my request as a customer? I noticed there were four
other lines connected to the box.

Jim;
There is a factory option cable pigtail which an be added
that will put most everything you could need on a external db25
connector... It can be ordered from an Icom dealer. You could build
it but I suspect you would have more problems with the internal
connector than is worth
Jim,
It's very easy as they are designed for those signals to be accessable,
much like the Motorola radios. There is a cable, part OPC-617, that plugs
inside the radio and brings those signals out to a female DB-9 connector.
You have to cut a few traces in the radio depending on the options you
About four years ago I had an old box on my home
for my Verizon North telephone service. It had the carbons inside from
1969 when the house was constructed. I started having noise on the lines
and called Verizon. Told them they were bad and needed
replaced. They sent a man out who changed

Hi Jim,
Many Icom, Motorola, Kenwood... yadda, yaddd brand radios
do the commercial mobile radio to repeater package. Most
newer decent quality radios have an option for external
interface connections.
The factory back to back cables work. Some layouts don't
do much more than a rude back
I have a motorola micor repeater that has the exciter keyed up all the
time, the TLD5322. I'm told if it is not setup like this that it will
have a delay in the keyup. The signal can be heard for a few miles
from the repeater site. Is there another alternative to this?

That's interesting to know Mathew. We're in the process of putting a
converted hi band VHF Micor on 220 and as it is set up now, the exciter is
keyed. I would guess that it wouldn't be much of a delay anyway. The final
stage of the exciter is keyed with keyed A- and I believe the xtal module is

The transmitter Channel Elemend is grounded through Q8 on the
Squelch Gate Board TLN4662A via Pin 3 on the edge connector.
Just be certain Jumpers JU-5 and JU-6 are in place.
The Q8 transistor is turned on by either a Keyed A+ (from Pin 6
on the edge connector) or Delayed Keyed A+
Does anyone have the step by step on hooking up two rangers

Rangers are not a particularly good choice for
repeater configuration due to the very wide front end and the low transmit duty

Joe,
I'm a current 'Bell Head' so I can probably offer up some
thoughts.
Telephone lingo varies greatly from one company to the next
and from one region to another. In Nebraska an 'A' Box is actually a three
position wooden box that's used to sit on while splicing cable.

Mathew,
Your advice is correct; if the exciter is not keyed 100% of the time,
there will be a delay on key-up.
But, the fact that you can hear the exciter's signal outside of the shack
indicates that perhaps:

It also makes the transmitter much more stable frequency-wise. In fact,
I made that exact mod to a Hamtronics exciter aver 20 years ago. Of

I should add that my mod was only 'hearable' within about 20-30 feet of
the equipment building. If you are hearing yours for miles, you might
want to look into it or mod it to switch the last 'always on' stage to
key with the amp. Also, check the power output. You should not see any
from the amp.
I have a pair at 223.840 (normal offset) available.
