I've not done it by a local gentleman has connected a
UHF R1225 connected to port one (the repeater port)
of an Scom 7K.
The controller second port (the remote base) is
connected to a GM300 on 2m channels.
The PL tone selection bits from the 7K (6 parallel
bits, output only) are connected to the channel
steering bits on the GM300 to provide remote
frequency selection.
I've asked the person several times for a schematic
and a printout of the 7K programming but received
nothing. At the moment the only R125 information
that repeater-builder has is located at
<http://www.repeater-builder.com/motorola/gr1225/gr1225.html>
If anybody does anything on a R1225 we'd love
to have a writeup on it for repeater-builder.

Highly likely yes. All of the controls exist to do so, and even if
using the built-in controller on the R1225, the 16 pin connector can
still be used for COR, PTT, audio, etc. You'll probably need
connectors, wires and probably a pot or two for padding audio
levels... maybe even a fixed resistor divider.
The internal controller will do you no real good on the link radio.
I'd be more comfortable with a "real" controller between the
repeater RX, TX, and Link.
I've been using a LOT of GM-300 and R1225s lately (anyone looking to
let go a used R1225 VHF in good condition?) and have pretty much
forsaken my stockpile of Micors, Mitreks, and even MSR2000s because
that little 16 pin connector and the software selections available
for logic and audio work so well.

Quick question:
I am planning on using a R1225 as a portable repeater.
Can the 16 pin accessory jack on the back of R1225 be wired to the 16
pin accessory jack a GM-300 to use as a link radio?
I want to use a UHF R1225 as a full duplexed repeater with VHF link
radio.
Thanks....
