Greetings,
I have 2 VHF micor's mobiles for trade. Both work but I am #1 a
uhf kinda guy and #2 a GE Guy also. (I have more experience on GE
anyway) I am currently running a Custom MVP on 443.800 with a RFS
(cellwave) Duplexer (little 50 watt jobbie). I would like to trade
these
Wonderful IDEA.. I will have to try that out on my CAT-200D... Any
idea where the COS/COR on that unit might be?

Matt,
I have four (4) of the partial NHRC-2 kits here and will need the voice
chips for them. Never dreamed they would stop making the chips.
Let me know how to reimburse you and the padded envelope will be in the mail
on Monday.
Thanks,

PRIMARY CONCERN: I am in the process of building a 70cm repeater and
need to know how to measure and test the physical and electrical
length of the short coax cables linking the (band-pass/notch) duplexer
cavities.
I read somewhere that these cables should be an odd multiple of 1/4
wavelength
IF you are a member of the ARRL they can help you and there is no charge.

I was recently told (by another ham) that I could ONLY tune up my 70cm
duplexer cavities using something called a tracking generator.
Unfortunately I do not have one; and judging the prices I have seem
for things with that name on the web, I doubt that I can easily budget
to purchase one.

Greetings,
I use a Signal generator (Wavetek 3007 signal generator) and a
Spectrum Analyzer Tektronix 7613 O scope with the 7L12 Spectrum
Analyzer module) Tune them up just fine here with that.
All a tracking generator is in a Spectrum Analyzer for what you are
using it for is a signal

You can use a sweep generator and scope for swept alignment of
filters and duplexers. The manual for your sweeper should show the
setup procedure.
If you don't have the manual, try BAMA or other internet sites.
You will need an RF detector probe or preferably a detector such as
the HP 423A

I did mine on FCC.gov recently; I'd give the site high marks for ease of
use. First thing you will have to do is apply for a FRN number. You will
need a password. When that's set up, the rest is easy, just log on and
check the boxes. I agree, I don't see any reason to go with the third

Hi Gang,
My Motorola R2008D service monitor went pooof the other day, blew the
AC fuse and let the all important smoke out of a certain part. I have
traced the problem to, what appears to be, a blown up RT (MOV?) on
the A3 power supply module. Can anyone please supply me with a
schematic
Your informant is essentially correct. A sweep generator is an instrument
that generates an AF or RF signal either linearly or logarithmically between
a start and an end frequency. By itself, it is useless for tuning cavities.
However, when its sweep voltage is coupled to an oscilloscope's
Duplexers and cavities have been tuned for many years without a tracking
generator or spectrum analyzer. It is a little easier with a tracking
generator or even a spectrum analyzer and a signal generator. But you can do
the job with a signal generator that you can keep on frequency and a
receiver.
Gran,

Cables between cavities include the length of the coupling loops in the
cavities. They are measured from the bottom of one loop, the cable, to the
bottom of the loop in the next cavity. You need to figure the velocity
factor of the cable and the velocity factor of each loop separately as the
cable
If you can't find the info from EMR you can look at most anyone's 7 cavity
specs and they will be very similar. Sinclair should have that info on their
web site.

Does anyone have a copy of the Motorola App NOtes for PLL from about
15+ years ago? I'm looking for some info on the R100 PLL. I have a

I'd take a scanned pdf, paper, whatever..
