Thanks Pop. I'll ask
the xyl to bring up your FB pages for me to look at, as I
don't use FB myself.

Hi
,
You may see the attached foto , zoom
in to see the red & green wires
soldered to the DIP relay points
Green
for Rx and Red for Tx which is fed to the
dual color LED ( three terminal type) the
centre goes thru a 680 ohms resisitor to
gnd.
happy
homebrewing

Well, I'm not sure photos would do,
and it might take several. Plus
there's 20 minutes of disassembly?
and re-assembly -
it's screwed to the box...!
However if you look at the schematic
- lower left:?
... you'll see
the PTT and the 'main' rel ay -
Pins 1 and 3 are RX+12V and
TX+12V, resp
ectively.
They're even LABELLED on the
schematic as RX and TX! They're
not labelled on the PCB, but you
can even test
this with a voltmeter. Pin 1 will
be +12 during receive. PTT and it
will drop and TX (Pin 3)
Pick off your
'GREEN' and 'RED' anodes. Most
Bicolor LEDs I've seen have a
common cathode,
so that
(center) wire is ground.?
You can pick up GROUND from this
same relay - Pin 16 of the relay
is ground.?
??
An even better picture can be seen
from the 'wireup' page: ?
?
The PTT Relay is right in front
(and down a bit) from the PTT
connector. PIN 1 is 'down' &
'right' (if you're
looking at the wireup.html page).
There's no need to desolder or
remove the relay. Just go
underneath and, strip your wires
SHORT.
You just need like 3 or 4 mm. Just
solder to where the relay socket
pins are soldered (remember
they're
'reversed' on the bottom) - Pin 1
- RX, Pin 2 - TX, Pin 16 (which is
opposite from Pin1 - it's a 16-pin
socket) Pin 16 is ground. You can
either run it to a connector and
'crazy glue' or hot-glue to the
PCB
just underneath (and to the right
of) the power connector - or, you
can just run them in the free-air,
maybe
use some shrink tubing to keep
them together. Just run them to
your Bicolor LED.
Hope that helps.?
Now - if I have some time this
weekend, I'll snap some photos.
