I recently bought a HP 8924c service monitor, now I need some help on
how to operate it. The reason I bid on it is I seen some ads stating
that the unit could be used as a general purpose service monitor, but
I need some help on how to set it for use on amateur radio freqs, so
far I have not been
If you don't have any documentation, Agilent still has the manuals in pdf form
available on line.

Can you take a picture of what you are talking about or
tell me where it is in the drawing?
I have a 4048 that was factory set to 2m so I can try to
get a piture of that or at least draw something that
represents what is really there.

Jim,
Going from memory here. Just to the right of the screen there are 6 buttons
marked rx test, tx test etc, might be circled in an analog area those are
straight up what they're marked. Then there's a shift blue button left of
those that make those analog buttons change to the blue description
Thanks for the reply and the very useful looking information

The 8924C is a CDMA cell phone test set, designed to operate in the cell
phone bands. While I am not 100% familiar with that particular version, they
generally were not designed to operate as general purpose service monitors,
like its predecessor, the 8920. You may be out of luck. Although as

how to make it work in the analog mode. Also,what would it take to
raise the input power to 60 or 100 watts? Answered a post about that
and the answer was more than I paid for the rig. Would think you would

There is a high precision attenuator resistor inside that needs to
be found, located, purchased, installed and calibrated. Easy enough
to do all but the last mentioned. The person selling you the

We have been having a similar problem here in Toronto on 224.86. The

carriers on the output. Many have suggested we put a PL on VE3RPT but
that is avoiding the issue. One member has observed that they seem

Hi Vern,
Please see the PDF here:
http://www.repeater-builder.com/db/db-4048.pdf
and look at the very last page. That is the way my duplexer WAS wired
from the factory at 156MHz. See the upper three cavities, they have
what looks like 1/4 wave shorted stubs attached to TEES on each cavity.
I
Yep, I don't have the extra stubs on mine.
I am not sure why there are there. One thing to keep in
mind is that this duplexer doesn't have enough to stop
desense in my MASTRII without adding another can. I added
a pass can and the repeater is much happier now.

How very true! One of the often-overlooked deficiencies of
bandpass/bandreject duplexers, AKA BpBr, is that they have only superficial
bandpass characteristics; their primary ability rests upon the notching
action. Only a true bandpass filter cavity has an effective and narrow
bandpass response.
Any IFR 1100S gurus out there?
I have one with a problem, head scratcher, tho I may have been looking
too long now and missing the obvious.
Problem:
On low freq, under 5 mhz there is an unlocked condition that the
spectrum analyzer and receiver see, but lock light stays solid during
this. Go

Thanks for all of the comments (well most of them except one). I have run my
220 machines w/o P/L up until the recent past. Never had one that really wanted
or needed PL, as in the late 70's when the first one came on, the 220 band was
occupied in the DFW area by only a dozen or so repeaters.
Hi- TKS for the up-date. The price quoted me was 750 !!! Thougth that was a bit
high. Don't know just how close I have to be for testing a repeater ? Jerry
