Thanks to everyone for their help. I opened everything up today... The VCOs
were locked- so I unlocked them. I did find the problem. The accessory
disable/reset switch seems to be malfunctioning. There are no longer 3
positions
on the switch. It stays in acc disable- I can hold the
Something else to consider is what we experienced on our two and 440
repeaters. Our 440 has a stationmaster type of antenna into the
duplexer into a preamp then into the Micor repeater. Most of the
electrical storms we had caused me to go to the site to replace the
preamp transistor. After

From the Better late than never department, next
time you have to move the station, don't put it face
down in the truck! Those switches come in two
versions: long handle and short handle, and they're
very vulnerable to being pushed in and broken, as
you've found out.
The best solution is to
The switch you need, SW801, is Motorola part number 4083980R12, shown
as: SW TGL BD MTG ON OFF MOM E107: List price $17.06. Motorola is
your friend (as long as you come with money!) Glad it was something
simple.

Eric,
Tnx for the suggestion - I called Motorola and after navigating - my
life history, etc. with the call screener - Parts ID said they no
longer support or have any info on anything this old. I also tried to
get the 68P manual number so I could search more, but they didn't
want to look for
Ron,
Tnx for your input. I have an older Mocom70 mobile manual that's no
help.
What I'm specifically looking for is the schematic on the Input
attenuator RF sense keying PC board, NLD7141A, so I can
enable/disable the amplifier from the repeater controller.

Yes, no problem. You may have to rotate/adjust the loops to get the
spacing wider depending on how they were set up and you will get less
insertion loss too if they were originally set up for close spacing.
Depending on where and how they are used at the site, you may want to

As to reference to this answer nowadays the 2 systems in a R.V. are 30
and 50 amps however the 2 companies that make them (world friendship and
Paralax) use 2, 40 amp fuses to protect the converter and the battery So
I doubt they are going to be any help with fuses such as those. I work

The switches are NLA from Motorola, but Digi Key has the right one except it
has a shorter bat handle. It works fine and fits the mounting holes on PC
board exactly. The hardest part is getting the front panel off the tray
