This one would work:

You'll pretty much need one with a total of six sections to get enough
isolation. Exception - TX/RX systems makes one with four sections that works
great.

Hello Nate,
I just finished the scan of the IFR1500 Application manual, I hope you
find it useful. It should answer many questions on how to set up the
1500, and even other IFR sets.

Hello to All,
I finished scanning the IFR1500 Application Notes manual this morning.
This Application Note book contains actual field applications of the IFR
FM/AM-1500 Communications Servicer Monitor. The setup described in this
document should also apply to other IFR service monitors, and
Hi Dick,
I have a bunch of these on the air and noted same problem when I used my ICOM
U 16 a while back. Check that the *123456* turns on the display. Then do the
*123456# and watch closely that each key press shows up on the display. You
might have one tone that is not decoded correctly.
I know you all will laugh at this one, but they say necessity is the mother of
invention. A while back a friend had the chance to try a tower site and wanted
a simple and quick way we could check coverage.
So with 2, ¼ wave NMO whole mount antennas and 2 18” satellite dish pans. I

I pulled out an ARR P432VDG GaAsFET preamp today, it's no longer working.
Anyone want it? I've standardized on Angle Linear; this ARR is one of the
few I still have in service and I have no interest in getting it repaired..
If you want it, call ARR and get an RMA number for the repair on Monday
I'll take it...

I assume you want the preamp (and not the Micor stuff). Let me know if you
want to call ARR and get an RMA so I can ship it to them directly - email me
the RMA# once you get it. Also send me your shipping address so I can put a
note in the box to ARR to tell them to return it to you.
73.
At 30 watts on a 5 MHz split in GMRS, you're looking at a minimum of 70 dB
of required isolation between the .30 uV receiver and transmitter. This can
be accomplished rather easily with a 6 pack mobile duplexer (assuming you
can get the full 75 dB of isolation out of a properly tuned high end flat
Jeff,
I'll take just the preamp. I will call and get the RMA tomorrow.
Thanks!

Years ago, we did a tower site range test with a guy that climbed up with his
HT. I drove around and talked to him on simplex to prove out the site and
potential of UHF. At the time (years ago) everyone kept saying UHF will never
work around here. Boy were they wrong.

Jeff,
I will gladly take the ARR PRE.

Looking for the schematics/ block diagrams or anything that would assist in
repairing the clubs Suitcase Repeater, the problem is in the power supply
system since this is an AC, 12VDC and internal 8 volt battery system it's a bit
dicey without the schematics.
This is one of the infamous
Eric,
Thanks for the reply. The Sinclair Q202G duplexers that I have do not have the
tiny threaded cap next to the loop connector. 1 set of cans are labeled as High
pass while the other set is marked as Low pass. I did notice a plate on top of
all 4 cans that has noting going to it but cannot
Ron,
Your Q202G must be an earlier version, with a different method of adjusting
the notch. A Sinclair bandpass cavity uses two loops, so the cavities you
have are not bandpass. A photo would be helpful.

Hi Jeff,
Just figured I'd give you an update...
Wasn't sure if the stubs were done for the 166 or
154 mhz incantation of the cans, so re-tuned for
166.
Looks like there is 2 dB loss at a 600 khz + spacing
(which is where the problems were). (all 4 cans = 2dB)
Also did a better look at where
I bought a nice looking RFS Celwave antenna to use on 462.600 Specs are DC
ground for lightning protection but is there something I need to do to make
sure it is protected? It sits on 3 legged tower 40 ft up and the tower is
mounted on the side of a structure. It sets on 3 pieces of galvanized
Eric:
I wonder if you are aware that any BP two loop cavity can be made into a BP/BR
cavity by using only one of the 2 loops, having a coaxial T connector on the
loop, with a tuning capacitor (in the form of a O.C. transmission line)
connected to one side of the T and on the other side a
19 matches
