Easy answer.
We have a Motorola of that vintage in as a temporary repeater --
our earlier Yaesu/Vertex and TPL amp failed last month after over 12 years of
full-time service.
We are assembling a new repeater system --
and plan to have the Kenwood TKR-850 as the main component of the new system

Surplus Kenwood TKR-820 units are readily available for $300 and less.
I have seen at least 30 sold in last 3 months on eBay. These purposes built

have the power supply, interface, BEEFY heat sinks for the TX RF transistors and

I submitted to Repeater Builders (WA6ILQ) the Programming Section (IV.) of the
HAL ID-1A REPEATER IDENTIFIER Manual.
This section describes how to properly solder the diodes (1N270) in the DASH
Matrix and SPACE Matrix of the ID-1A
for the creation of a CW message (Repeater ID).

I have 2 of the HAL ID-1A units that I picked up surplus from a Western NY
utility company last year.
They used these 2 units on their older repeater systems (circa 1970s) -- and
one unit -- was converted
fro 120 VAC to 12 VDC.
YES, they are diode matrix programmed (for ID) -- which

It would be a very interesting court case in this state (Illinois).
Illinois is where Air rights were established 100 years ago --
above railroad right-of-way (that railroad could and did sell).
It was the communication attorneys (and FCC) that used that landmark ruling --

It is called the Tesla Effect, for Nicholas Tesla who first worked on wireless
electricity in 1891.

He was performing work in New York and Colorado Springs .. covered in his
biographies.
Google his work at Wardenclyffe.
He had an insight, and we may

The Icom IC-22A is crystal-controlled, so has ultimate flexibility (at the
price of crystals).
The Icom IC-22U came after the IC-22S (23 channel with diode matrix board) --
I had the 22S one in late 1970s (popular unit at the time).
Generally, I have seen them sell on eBay for ~ $15 to $50

Contact your local (country or region) Microchip distributor or dealer.

Did you check the resistor (for voltage drop) on that LED??
It is very possible that resistor has either changed in value or
the value may have been mistakenly read (red for orange) during final assembly
(it happens).

According to my notes, this radio needs the Kenwood KPT-20 PROGRAMMER (which is
a standalone device)
( TK-210, 310, 220, 320, 230, 330, 710, 810, 620, 720, 820, 622R, 722R, 822R,
TKB-620/720,
You might look ar Noalox (Ideal) / Pentrox (Burndy)
DX Engineering also sells a thick Marine Grade version ...
I have a can of it here ... if you want to look at that stuff.

I have no idea why you are using Bomar,
other than maybe to save a couple of dollars.
I have always used ICM (as well as all 2-way / LMR technicians I have known)
ICM guarantees their work for life and replaces crystal/elements.

Absolutely GOOD ADVICE -- so that you wil inimize problems once your repeater
is installed.
I would select a nearby Kenwood dealer and ask them to align/setup the repeater
AND
the actual caviities that you are going to use (actual antenna also -- IF you
have it)
Should cost no more than 2
IF you use the short 25G tower section (~ 4 feet) in the hole (this is one
approved approach) --
make ABSOLUTELY sure that the bottom of the hole permit drainage of water
(small sized gravel in bottom of hole) -- the hollow tower legs/tubes into the
hole MUST permit drainage of water captured
