Yes Doug,
Sent a recording off list but you have I think hit the nail on the head

lugs ( one side) on a mobile duplexer will suppress that noise ~65db,
and provide no significant insertion loss to the link tx..And double
shielded cables like RG142 for radio to filter connections is perfectly
adequate up to 520 mhz and beyond... with isolation to -120dbm at a
minimum..
Doug
At UHF, possibly, at VHF unlikely... you did not specify :-)
How close are the frequencies??? Lots of details left out for us to help.
If the freq's are within a few hundred kiloherts at vhf, antenna

My GROL is in the database, although the grant date is incorrect. The
database shows a grant date in 1988, but it was either 1983 or 1984 when I
actually received it.
I wonder if it varies depending on the office of issue? I took the test in
Tampa.

Thanks Eric..Reading the spec, it appears they both have a loss of
33db/100 feet
at 400 mhz. Most interesting...

Thanks Bert.. I remember using it even further back... Hadn't run across
it ever since until this piece showed up. Another conversation piece I
guess..

Can someone tell me what the characteristics of this cable are. I tried google
and it didn't seem to know.. I sort of think it might be a lossy coax but
not sure.
Thanks

like me.
They have also fought for me on issues that went bad and found in my favor
100% of the time.. again usually in days.. not weeks. as they have specific
time policies for arbitration.. and they are quite reasonable.

I have a vhf radio presently on 162mhz made by E.F Johnson.
It is a small unit, but I can't find a combo. It has a
FCC ID ATH90F2427152. The number is very faded and hard
to read.
Can anyone tell me anything about these. Are the useful
for hams and how can they be programmed.
Thanks

From whom did you order the controller??

as Maxtrac and almost ALL the
GE-et-al 900 radios share a common PLL chip.. it is not magic to program
