Paul,
Have you tried using a different instrument to view this spur? Some
spectrum analyzers and service monitors create an artifact of the viewed
signal, due to some unintentional internal mixing. When three different
radios exhibit the same oddball symptom, I'd suspect my test equipment

910 Kc is twice the 455 Kc IF. Possibly there is a clue here. Motorola had
problems with spurs in the Metrum VHF ham transceiver. It also used one
crystal for both transmit and receive. I guess that this is a good data
point as to why mobiles should not be used as repeaters. The repeater a

Eric,
Thanks for the reminder never to trust a single instrument
too much. This spur is verifiable though. It can be heard
on the air when the Micors are running into an antenna, up
to at least 5 miles away if it is a true line of sight path
and there is some antenna gain at both ends. And
Thanks Glenn.
When I first noticed the 910 kHz relationship, 455 IF was
the first thing that popped into my mind... until I
realized the Micor doesn't have a 455 kHz IF. Darn,
another good theory ruined...
Since I have 3 similar radios exhibiting exactly the same
problem I am thinking this m

Thanks Ken.
The spur is there even without audio. But no, I'm not
bypassing anything... controller audio is fed to the
microph
Are you sure it isn't something caused by your service monitor? Have you
tried a different one, or is there anything else common to all three radios?

I just joined the S-Com list and I posted this question there - but as

can get an answer before I waste too much more time.

It sounds like you are on the right track! Keep going!!
A few years ago I had a local ham tell me my UHF repeater was producing a spur
on his UHF output. He made a fuss that I was not running good gear, or
adequite filtering. I assured him that I was fine & had checked it out with
my equipment.

I've got one that I'm trying to track down..
A local 2M machine, on 146.730, is having a problem we call "the
horrible noise".
I've never heard anything like it, and I've had no success at recording it.

I am trying to modify a 900 mhz paging station (model C75JZB-a)
into a 900mhz ham repeater.I do not have a book on radio. I need to
know if freq. syntheisers can be reprogramed to ham freqs. or do I
need to convert to channel elements. Will 800 mhz micor elements work?

Thanks for the advise Eric.
Jeep Cherokee's have a metal roof. I have tried the
antenna on a second mount I have on the back of the
vehicle with the same results. I have also checked
grounding and ohmed out the cables. Not to mention the
Larsen antenna I have works just fine on the same
mount.

I'm in need of manuals for a hi-band Aerotron
cabinet style base station, that I hope to make into
a repeater.
The Model numbers are:

I've been following the UHF Micor "Spur" thread and have to also
agree with Joe's analysis (up thread) that 910 kHz "spur" is likely a
weak image in a receiver looking at strong signal. I've seen this
happen many times when someone close to the repeater site complains
of hearing "spurs" on the o
