Hi folks... Want to wake up this venerable old radio and use it for
some packet work... Was wondering if anyone out there had information
regarding this radio.

I'm interested in the power output of this radio. I'd like to compare
the design specifications with my currently observed power output.

I'm curious as to why the channel selector runs
1,2,3,4,5,6,A,B,C,D,E,F. Why numerals 1-6, and then letters A-F?

I'd like information regarding the layout of the crystal sockets.
When I install the new crystals, It'd be nice to know where to put
them...

According to an ad in the June 1972 issue of 73, it has "15 watts
minimum output" (at 13.6VDC).

It has sockets for 12 receive crystals, and sockets for 6 transmit
crystals.

This rig dates from fairly early in the 2M FM boom. There wasn't the
level of standardization, and there weren't so many repeaters. So at least
some rigs made it easy to use a crystal more than once. For instance, .94
was a common simplex frequency, but .34/.94 was also a common repeater pair.
You might want to use that receive crystal for both combinations,
while switching in the other transmit crystal. So you'd get
more switch positions than crystal sockets, and some means of jumpering
to put the same crystal in more than one

That's the case with this rig. If they went from 1 to 12, it's not
as clear which of them are reworking the transmit crystals. Obviously,
the letters make it clear that you are now recycling the transmit
crystals. (And thinking about it right now, it doesn't fully make
sense. It seems more likely that you'd want to reuse the receive
frequencies, so you'd want more transmit crystals, to allow for
transmitting on .34 and .94 with that .94 receive crystal.)

Internally, there must be some means of strapping the crystals
to go with the switch positions. I never had one of those, so
I wouldn't know the details.

Look inside. Maybe the sockets are marked on the circuit board.
It may at least be clear that that there is a bank of six sockets,
for transmit, and 12 sockets for receive. And if you have any crystals
inside, they likely provide some information about which are the transmit
and which are receive.
