I've experienced problems similar to what you describe on several MII and
found it to be harmonic noise on the ptt (osc 10v) line. Installing
a 10 uh inductor where the line enters the exciter pcb did wonders for
mine. You may also want to install a

Bob, I have four repeaters in service using a Zetron
38A controller, and had the following experience.
When I enabled the courtesy tone at the end of a
transmission a station that was on the edge and
'picket fencing' would be unreadable for all the beeps
the controller would insert. It seems the

Thanks Bob Paul for the response. Yes it is the unit with the
compensation line running between all ICOMS. This is kind of where I
have been leaning to.. Course

Yes I checked power levels and change in power has no effect on the
issue. Yes see where the connections are on a station/repeater.
More a question of how of it. With Molex connectors on backplane or
what works the best?

If the spur is causing a particular problem to someone
and is caused by some harmonic of the LO chain beating
with the transmitter, you could move the beat by
changing to the opposite side injection on the
receiver. Check the new beat frequencies to make sure
you are not just trading one problem
Randy, a method I have used a couple of times is to
take an old computer card back-panel with a cutout for
a 9 or 25 pin connector and bend it so that it picks
up a couple of screws on the rear of the card cage top
or bottom. (You kept those and did not throw them away
did'nt you) I then wired the

problem MII and look at the ptt line. He may be pleasantly surprised.

Hi Jim, So you just solder wires onto the back plane circuit board?
I quess this is my quest to see where most people connect to the
repeater.

Yep - I used the info on the Repeater-Builder site to
identify the pick off points where the signals are
found, and soldered directly to the backside of the
pin that the boards plug into on the other side. You
can figure out which points they are by looking at a
schematic of the card cage also.
QSL Jim and yes I am aware of RUS CAS and with the dual squelch mod
as have been running MastrII mobils for years as repeater and MVP's
for remote RX and links. Kind wished the PS unit was set to loop out
to a voter and back. Guess we can roll our own. Still to looking for

Hi Jim,
Makes a pretty clean installation, although one
of the controller manufacturers on here recommended
against using computer serial cables as interconnects
for controllers
That'd be us. A PC cable consisting of two D-sub connectors and a long,
25-conductor cable enclosed within
17 matches
