That unit would have needed a C800 or C900 control head and was most likely
a SP build for a Federal agency, several generations back as radio systems
go. The dual RX allowed the radio top have good sensitivity in both the 163
and 167 ranges as the front end filtering were not that wide and/or
I recall seeing posts from several who have used the Diamond X500HNA antennas
with good results. We've got a VHF machine with one of these that's going back
up. It was taken down because of a noise problem and sent back to Diamond for
repair. It was/will be top mounted.
For those who are
A group I was in used to use both some Comet and Diamonds. We
soldered the element joints AND covered the radome joints with the
fancy heatshrink with the glue in it. They held up for at least 5
years before I moved and lost track of them -- they were also top
supported, and I think that
Did you use silver solder or typical 60/40 or 50/50 solder?

Can some one with one of those fancy programs like Comm-Shop run it and tell me
the max power a Exec II on UHF ham band run with a 75 isolation mobile
duplexer. Assuming that the coax and ant are a ideal setup.

I'm betting it was 60/40 since it was just the Kester spool in one of
the guy's bags.

I have 5 boxes of mostly Motorola service manuals, some GE.
Mostly 60's 70's vintage, i.e. micor, mocom, ht200, flexar, remotes, base,
mobiles, etc.
I can send you a file with the list.
Free to good home/amateur use, but you must come get all of them, Im not
shipping.
Contact me directly.
Where are you loacted CHris?

Yeah that's probably the matrix

Randy,
Using a TX frequency of 443.000 MHz and a RX frequency of 448.000 MHz, and
with a receive sensitivity of 0.35 uV, my CommShop program calculates that
100 watts of TX power requires at least 74 dB of isolation. Since a mobile
(notch only) duplexer is hardly an ideal choice, I'd suggest
Thanks Eric, That is exactly what I was needing to know. This will give us a
good starting point and since it is looking to run only 35 watts it should be
OK. That is better than I expected. Anyway I believe it, (the duplexer) is
only rated at 50 watts.
Your a gentleman a scholar.
Thanks
Mike,
I have used and had good luck using model paint in the small 1/2 ounce
container and a model paint brush.
