Just a brief note on two towers I had installed for over 35 years. I used
three of the Radio Shack mast base mounts in the ground to support the tower
with Rhon house brackets. These units consisted of a square metal plate, about
six inches, with an 18 inch piece of sharpened angle welded to

Judging from the variety of responses to this thread, there seems to be far

John,
Perhaps it's just as well- the data sheet on Com-Spec's fax-back service is
incorrect, page 4 is a duplicate of page 2.

LVD 75 Amp Relay Source.
Per my post regarding the Low Voltage Disconnect information. I
was able to locate the Bosch 75 Amp Relay from the www.solarseller.com
web site, which appears to have a lot of goodies, which might prove
handy for repeater dc back up systems.
Hey guys,
Alright, I need your help. Anyone know of a good supplier with some UHF
maxtracs? I need a handfull of them.
I need the ones with the 16 pin connecter.
Thanks,

I have a Delta table top base (low band) that I am trying to find out
which lbis apply to it. So far I know that the id plate says that it
is a N3A016. I will dig into it more shortly to try and id the main
modules in the radio itself shortly.

Have done a Micor repeater using the CAT-200 controller. It's really quite easy
to do. Pull all the cards except the Station Control and the F1 PL Decoder. A
mid split PA will work if the output is 147.00 but I don't think a high split
PA will last very long.
Strongly suggest if yours is
Gale,
I looked up N3A016 in my GE microfiche file, and I believe that it is a
Package Number which was often used in place of a combination number when
it was a standard model. However, the package number listing begins at
N3A101 which raises the possibility that the number may not be correct.
Want to fire me off a copy as well. I like to see the different ways it is
done. Maybe then I will pull the micor back out and see how I did it!!!
Thanks! Corey N3FE

I have a couple of GE ER-41C VHF (138-174 MHz) FM receivers complete
with EP-39A -110vac power supplies for the cost of shipping. Both
receivers and power supplies work fine. If anyone is interested, please

That last comment about the spectrum analyzer is an excellent suggestion.
Trying to solve such interference problems with cavities or isolators may
involve far more effort and expense than necessary. Here's a case in point:

Your experience reads like an O.Henry short story and punch line. Right up
till the end, I was convinced that you were going to find an external mix

All,
I am hopeful that someone out there has a clear and complete paper copy of
GE Datafile Bulletin 10008-5, entitled Measuring FM Deviation by the Bessel
Null Method. This is an eight-page document authored by Jim Carrington,
back in November 1967. Although I have a copy of this document on

I have looked at it, here is the dilemma. The channels are
pre-programmed into the tx and rx decks. There are rotary channel
switches to select the channel( at least in the ones I have) . Valid
channel numbers are 1-400. 401 unlocks the vco. Both tx and rx react same.

Look up the pager intermod filters that PAR Electronics sellsI have had
good luck using them to fix a similar situation here-I think that one would
have fixed your problem.

Scott,
I did check the PAR Electronics site, and I am impressed with their designs
and user kudos. However, it is not easy to notch out the pager at 152.480
MHz and not attenuate my commercial channel at 152.345 MHz. The point is
now moot, because the Motorola CDM1550-LS can operate at 152.345
