It looks like the FCC rules give you extra power when opting for dual
polarization.
No, they don't give you extra power. For commercial stations, horizontal
polarization is the standard. You can supplement it with vertical, either
as cross-polarized linear, or as elliptial/circular, but that

How did you determine it's an IM product?
What repeater/controller combination are you using? I'd try powering down the
controller and manually keying the transmitter. If that solves it, it could be

Some additional information will be helpful. What makes/models of equipment
are in your repeater? Are all jumper cables and the antenna feedline
double-shielded? Are any of the connectors nickel-plated? Are there any
barrels or adapters in your jumpers? Is there an isolator/circulator

Absolutely! Isn't a recurring theme of this list to keep the old tools that

Hi Guys!
I am in the middle of rebuilding a receive site for one of the area repeaters
and have come across some interesting Pin Gunk. I've been told that Motorola
techs years ago used to apply some kind of goo to help with the connection on
all the backplane pins, etc, but I don't know if

I have inserted a 6dB pad in the antenna port of the duplexer and found that
the IM products drop 12dB, and also curiously, the frequency of the products
change. Removing the pad reverses this effect.
The above says that it's a 2nd order mix, F1+F2, F1-F2, 2F1 or 2F2.
Since it looks to be

Look around for a switch mode power supply that uses 600kHz as the

Also florescent twist lights are really good for making desense on

Hi Mike,
thanks for your post - I'll think about this a bit more. There is no isolator
on the TX - will add one (and BP filter) when I next go to site this week.
The radio is synthesised.

Hi John,
I thought we may have a dubious TX issue - either spurs or as you say something
unstable or oscillating.
I replaced the TX. It had no impact on the problem. The issue appears to be
external to the TX.
Also I have terminated the duplexer into a 50ohm load and looked at the RX port
Paul,
no fluro lights on site. Actually no lighting at all - the site is solar
powered so little capacity for lighting.
No repeater ocntroller - the RX is directly connected to TX via a very simple

I believe it is an IM product because the RX requires a CTCSS

all cables are double shielded. No adaptors are used. There is no isolator on
the TX side. Connectors are silver plated, with gold pins.
Antenna is a single folded dipole mounted about 15m above the equipment

Thanks - no battery chargers on site as all solar powered. There are solar
charge controllers, though I think I have discounted these.
No fluros either.
All equipment was switched off for a test, so any SMPS should have been off.

Depends on the vintage of the receiver and exciter modules.
Are there any numbers on them?

Thanks Niteviser,
Will examine further, looking at the board it appears that there is only one
data line plus ground so that rules out the normal type level converter circuit.
Thanks again for the link.
