George,
I have a KXN1086 on what appears to be 47x.8625. (Can't tell the exact freq
- the label is pretty beat-up).
If this is of any use to you, it's yours for the asking...

George,
With the upsurge in FRS equipment this might be a worthwhile modification.
Since the standard GMRS channels are 25K spaced and the FRS channels are
dropped in between both the inputs and the outputs it is possible that a
standard 25K rx will receive portions of the audio from adjacent
Hi Skipp
I think you'll be interested if you know that all the unit are new and still on
original box. (MRS204EX-220 MHZ narrow band repeater) they have 24 unit for
$50.00 each (ARX2125Z-110 watt 220MHZ RF P.A.) they have 12 unit for $125.00
each. you can find them at...

Best case for nowit can be modified for 900 rx with
information available at this time.. even that is a lot of work
Many better donor radios to work with that are already in 900... Most

Hi Camilo,
Thanks much... yes I purchased a number of the arx-2125 pa units
from BKRelm in the past. But getting them to work on the 224 MHz
ham band is not so easy. N2CKH and myself are probably the only
two hams actually using the amplifiers in Amateur Service. At this
point in time I'd
Can anyone tell me the features of the internal controller for the
IC-FR4000 repeater from Icom. I have sent Icom America, in Bellevue,
an email with no reponse yet. Info on the web site is vague.
TIME OUT TIMER?
TX HOLD TIME?
CW ID SPEED?
CW FREQ ADJUST?
SINGLE OR MULTI DIGIT DTMF CONTROL?
I'm looking for any documentation I can find for an old (maybe 3+
decades old) Microwave Associates PM2-MF power monitor. It's a
typical dual direction in-line monitor with outputs for FWD and
REV power, N male to N female connectors. I've talked to several
people at M/A-COM and they can't tell
The extra length of the VHF cavity used for the 220MHz duplexer should
do nothing to the tuning, insertion loss or notch depths. I suspect
there may be another issue with your observed results.
Did you measure the poor performance without tightening or inserting
ALL the screws on the top plate?
Where is a good source of information (including manuals and curves) on the
web for Decibel Duplexers? I would like more information than the list of
duplexers given on RB.
Thanks.

You seem to want to lump what is characteristically a complex impedance
(R+or-jX) into a single number in order to simplify your argument that a
non conducting RF output transistor is an open circuit because the
transistor is not having any RF drive

Pass transistors are the usual culprit.

Usually one or more of the diode rectifiers on the
chassis short out. This causes the main 8A fuse to
blow rather quickly.
I had this happen to two RS35 supplies in the last 6
months.
However the main filter capacitor could also be bad.
At least that's easy to disconnect and measure with an

Hello List,
Does anyone know where I can acquire or download an IFR-1100S or GRM-114A
service manual or even just a schematic? Thus far, all I've been able to find
is a calibration document that has no schematic. Since my problem is power
supply related, the 1000S manual available everywhere
Kent,
Please be more specific. What is the model number of the duplexer for which
you need information, what frequencies is it currently tuned to, and what
frequencies do you want to tune it to?

The pass transistors are shorted, unless lightning shorted the rectifiers.
Hopefully the fuse was correct and blew before the transformer was damaged.
