But sometimes it takes a lot of work to make that happen correctly.
I bought a house 4 years ago. To create my ground system, I drove a 1/2 inch
copper water pipe into the ground, then welded 4 inch copper strap to that
copper pipe. Within (approximately) the
As Eric points out, this duplexer doesn't provide a lot of isolation.
Usually 90+ dB is required and more is often necessary, depending on
several factors like the actual receiver sensitivity, using a preamp and
how good it is, and the actual transmitter power level, spectral purity

My club has a GE MASTR II mobile modified repeater controlled
by an ACC96.
The ACC96 has a small satellite board plugged into
socket U33 on the right side of the main board. There are two
chips on the board: SN74HC74N and PAL10L8NC.
Transmit audio is good going to the small satellite board, but
FIrst the chips that you listed are both digital chips and should
not have anything to do with the audio. The 74HC74 is easily found
BUT the PAL device was programmed by the manufacturer and that is
the source. Again, Look for the problem some where else.

Larry,
I think you have the right answer. I can't think of any other reason for a
digital connection to the Control Receiver jack. I have gone through the
RC-96 manual from cover to cover, and have not found any mention of an
optional serial board. I'll poke around the ACC archives at Link

Why would it build up a charge? If the strap is conductive as it
should be, it would be a connection to ground. No?
Umm... connection ??
The 'theory' may be as a 'conductor' to ground .. but I can't imagine
dragging it on concrete would really qualify. Maybe on dirt, or crossing
a RR track...

for $55. It was intended to allow channel selection and limited
