If that is what it is, here is a manual:

It's model name was RP3A if I am not mistaken, made originally for the MVP 
mobile to turn it into a repeater. It was built to replace the factory cg 
board. It has no remote control or cw functions. Just repeat audio control 
and carrier control. It used a comm spec TS32 for encode and decode. Made 
by Parkinson Electronics. in Texas I think

[Repeater-Builder] What is it?

[Tom Parker]

Hello to the group,

Anyone know what kind of repeater controller I have?  A guy brought a
Mastr Executive II  into the shop for repair and we all
started wondering who made the controller.  It would be nice to have
some documentation if it ever really fails (only the 5 V Reg this
time).  Kevin has been so kind as to post a couple of pictures I have. 
Maybe someone will recognize this beast!

Re: [Repeater-Builder] What is it?

[Neal Newman]

Before you go and cut down this UHF slotted dipole antenna Off the top..
 My questions are Do you Own the Tower? or just another Tenant
using it?
 make sure that  No one using it.  it may no longer be  used for a
translator, However
 It may still be used by a local LPTV station. 
 Personally I do not thing that the slotted dipole is the cause of 
interference...
On our Tower the static problems were caused by oxidation on the Guy
Cables
 and in  the tower sections... We ended up Bonding all the Tower
sections together with straps
and lube all the Guy cable Connection points with Lithium Grease.
 this solved  our  repeater noise problem for almost 2 years... Just
recently   the noise came back.
 BTW  I would use the Lithium Grease on each of the sections of the G7
also  then use Heat shrink to  seal  over the joints so the weather
does not affect the grease.. My G7 on 220 has been in operation   
since the late 80's with no problems...

Re: [Repeater-Builder] What is it?

[Glenn Little WB4UIV]

I suspect that the UHF TV antenna weighs in at 1000 pounds plus. From the 
picture, it appears that this antenna has a flange midway up the array 
where the array can be separated into two pieces.

Possibly you could remove the UHF array in two pieces and better mount you 
ham antenna.

I do not think that the average gin pole would do to remove the array.

I have to agree with the others, the noise is probably coming from the 
amateur grade antenna placed into repeater service.

The folded dipole antenna are much better in that they survive lightning 
and rarely go bad. Because they are grounded, they are much quieter and the 
equipment attached to them is much safer.

Re: [Repeater-Builder] What is it?

[Paul Guello]

I agree that your problem is the antenna, also check
the feedline and also the tower for any loose metal
within the aperature of any antenna.
The UHF TV antenna could be very heavy, 1000# +. 
These are usually installed using a very heavy duty
gin pole and a winch.  You might try testing it first
to see if it could be used on any ham band.  Some of
these antennas are pretty broad band.  It might just
work on a UHF ham band.  Also, it could be an ITFS
antenna (2.5 Gig range).

How long has the G7 been in service?  We has one on W5LM/R that worked
great for a couple of years, then became very noisy to the point that a
1/4 wave mag mount worked better - we replaced the G7 with a DB244 and
things have been FB for the last 10 years or so.  I suspect corrosion in
the joints.

Re: [Repeater-Builder] What is it?

[russ]

The guys are right on the G-7 but what are you feeding it with? What are
your jumpers made with? Coax such as Belden 9913 and Times LMR 400 type
coaxes will do the same thing. Your jumpers should be made from things like
Belden RG-214/u, Andrews 1/25" super flex or Andrews 1/2" super flex are
always good for jumpers. Your feed line should be some sort of Hard line
type Coax. Like 1/2", 7/8" or most of our stuff is 1. 5/8" it all works
well.
Just mite want to look at your feed lines as well. Some times it is not even
your omni that is doing the receive scratch.
Good luck!

Re: [Repeater-Builder] What is it?

[Mr. Edgar McKinney]

Sounds like something I had once before in Fla.

Questions to consider

Is the tower painted?

How often are the tower's jointery checked and bolts loosened and
retightned?

Is the coax grounded every ten feet? And is the coax (hardline( on the
outside of the tower or in the middle?

Is the tower grounded using ground straps vs round cables? Are there more
than ten ground rods? Are their diameters larger than 1 inch?

What about the coax's entry into the equipment shelter grounded?

I have discovered that if there is a problem with any of the above will
cause the problems you have discribed.
Also are there others on the same tower with faulty or loosened pieces of
equipment, antennas, clamps, grounding strapps loose

Just a thought.

Re: [Repeater-Builder] What is it?

Steve,

I think the Hustler G7 is the cause of your symptoms.  It's a light-duty
antenna with many joints to loosen, and the thin conductors are prone to
hairline cracks.  My club had a brand-new G7 donated to it for a
repeater, but it was scrapped after less than a year in service for the
problems you describe.  As a general rule, vertical fiberglass antennas
that require assembly of the internal elements are not the best choice
for repeater service, especially where the winds are constantly flexing
the elements.

As for the translator antenna, I suspect it weighs a lot more than you
think.  You might contact the agency that had it installed, to find out
how it was erected.  It might have been emplaced using a helicopter. 
How high above ground level is the top of that antenna?

[Repeater-Builder] What is it?

[Steve]

We are getting some strange receiver noises (intermittent 
pops/cracks/static) as well as sudden losses of sensitivity on our 2 
meter machine.  This is what the top of our tower looks like:

The thin white vertical is our Hustler G7.  The other antenna is what 
I'm asking about.  I know it's probably a late 70's era UHF TV 
broadcast antenna...our site was used by the county gov't for a TV 
translator site before it was abandoned.  It needs to come off, but 
how much does this thing weigh?  I don't want to tie a ginpole to it, 
loosen all eight bolts and find out it weighs 300 
poundsespecially if gravity suddenly takes over!!!

[Repeater-Builder] What is it ??

[Johnny]

I am the proud owner of a TFE 6050A.
Now I gotta figure out what to do with it.
It is 2" x 1" x 5   with 2 cables permenatly attached on one end and 3 
adjustment screws on the other end.
It came with a little TFE 6030A  4 cavity Motorola mobile duplexer.
