I have searched the archives to no avail so here goes. Could someone
tell me the primary differences between the Version 1 TKR-850 KPG-66D
software repeater and the Version 2 TKR-850 KPG-91D software repeater?
I am particularly interested in the difference between DTMF over the

Hi everyone - new to the group looking for help on a strange problem.
I've been involved with two repeaters in Southeast Kansas (Humboldt -
147.18 and 442.900) for over 30 years and work in Electronics,
although not in radio. A couple months ago we lost both repeaters
when we had a flood in this
Ok guys help this old man out. I worked in a Motorola Shop back in the 80's.
I seem to remember a problem with Micor UHF PA's where the solder connection on
a perticular chip capacitor would go bad causing the power to drop to next to
nothing. I think the solution was to resolder the cap

Our group has plans of putting a Spectrum Communications SRC 1400
Repeater in operation. This was donated to us by a friend who has this
stashed away in their warehouse for a long time.
Some of the wires have deteriorated and cut off so we urgently need a
diagram to have this repaired and

I need a good VHF-25watt PA module for a GE MVP (19D424309G2 or
similar). Anyone have one?

Ryan,
Here is a very useful link that will show you how to align the unit into the
ham bands.

You might be thinking about the 33pf(? value) on the collector/emitter junction
on the flat pack RF transistors. Or the leaching problem that is mentioned in
the service manual. I always replaced the chip caps on the base/emitter and
collector/emitter junctions when we had to replace a
Hi Shane,
The two main differnaces between the V1 V2 repeaters are yes the DTMF
control. I think the main differnace is that the new V2 repeaters have a two
stage final amp and the V1 repeaters hace a three stage amp.
Both repeaters can operate as a standalone repeater but the V2 can be
Dan,
My guess is that the duplexer tuning was disturbed when you took it apart.
Most likely, the notch for the RX frequency on the TX side is not exactly
tuned to notch out the TX carrier, leading to major desense of the RX.
Unless you have a network analyzer, or a good spectrum analyzer with

There is a liquid silver plate compound I've found does actually
work in some applications. But there is no realistic fix for some
types of damage.
For a damaged duplexer we swapped the rx with the tx bottles so
the tune plunger and contact finger stock were in different physical
locations.
Also check the 52 pf coupling capacitors between each amp stage. We see
these go bad and intermitten from time to time. Still too cheap not to
replace, but sometimes all they need is a little heat and solder reflow.

Hello all. I have a UHF Micor mobile Repeater built by Matt Bush when
he had Advanced Repeater Systems back in '93. It Still runs fine but I
would like to get ahold of Matt to see if he has a better controller
for it. If anyone knows how to reach him please let me know. Thanks.
You are probably referring to Matthew H. Bush, KA9RIX. You can look him up
on QRZ.com or on the FCC site.

I'm considering a trunked (type TBD) system on 470 that will have

The overlap comes about due to the need for multiple sites to fill the

Bill,
Though I have no personal experience with a trunked simulcast system, I did
have a class from the engineer assigned to a large end to end system that the
company that I work for takes care of. Among the other problems that may arise
are frequency stability which the GPS should take care.
Skip,
You bring up a very valid point. I only know of two IBOC listeners in
the area. The local PBS station is trying to hype it so that may generate
some interest, at least for their classical music station. They hope to go
IBOC soon. Yes, keep those cards and letters coming in. How about
The idea with simulcast is to keep the non capture area as small as
possible. Typically the capture area is that where the dominant
transmitter has a 10 dB or greater advantage. In capture areas
subscribers hear only one signal A good test is to broadcast different
