Both my Motorola Signal Generators developed an intermittent with the 1 kHz
tone and I pulled the units out of the case and cleaned the pins on the PC
cards.
The old red ruby eraser trick worked like a charm. I also found a light
coating of a greasy film on the contacts which I cleaned with a Q tip and
alcohol before applying the eraser.
I use mine for duplexer tuning since they have a lot lower signal leakage than
my service monitor. A double shielded cable between the generator and the 6 dB
pad at the antenna connection allows me to use a handheld radio to tune for max
on the pass and also tune the nulls. I use another 6 dB pad at the port output
to the talkie and a 50 ohm load on the other port.

I have 2 Motorola S-1320A-1 Solid state signal generators in my
shop
that I need to service. One has intermitant 1000hz tone sometimes it
works and usually when you need it it doesn't. The other has a power
supply problem. I would like to find a manual for this either borrow,
rent or buy. I use it for repeater site work and it takes a beating but
I can't afford to upgrade right now. Does someone out there have a
manual on the shelf that would be willing to assist. Thanks Art. Can
