Anyone have a source (and/or part number) for the on/off push button
switches controlling the C-4 Console Power?

Nice of them to design the device to contain the magic blue smoke, though.

Garey and all,
To my way of thinking, there is less chance of reversing the connections if
you use a Jones plug. It's hard enough to keep everything straight when you
confront the maze of wires for multiple transceivers and other equipment
even if you have only one amplifier.

Yes, that is a good way to speed up the amp keying. A half mA shouldn't be a problem, those lines
are 'fused' very closely, but they should survive that! :-) Saves a whole ~25 mSec!!

Yeah, I understand engineering to price points. On the smaller rigs, it's more
an issue of availabe real estate on the rear panel. Doesn't mean I have to LIKE
it... :)

Gary,
You mentioned the VOX pin being a real relay.
The H&K pg 37 Nov 1988 QST shows a way to use the motherboard 10V TX line and a
few components to key your amp sooner/faster. I am looking at doing that only
for the extra "speed" in getting the amp in line. Based on my tests so far, it

I'd be inclined to use the fixed 'line' AUDIO jack. The counter input can be handy, obviously as a
counter, but also as a good quick troubleshooting tool for the radio.
The other alternative of course is to get the proper connector, they are available, or use the

Gary,
Any ideas on where to put another RCA jack for the VOX relay? Maybe steel the
counter input?

Remember Jim, today's engineering staff (or should I say finance and marketing
engineering staff) is not to worry about your cost of ownership. They are
there to get the equipment sold at best profit margin possible and then
obsoleted so that you will buy another. It's all about cash flow.

Hi Evan -
Simple!! The TR-3 was designed for mobile use, no amplifiers and minimum number of connectors to
undo. This is the reason for the speaker connector coming out of the back of the power connector.
The AC-3 had no VOX or ALC connections either.
Then, here comes the Twins. My first T

Perhaps they though the rear panel of the radio was getting too cluttered. More

Curious as to why the VOX and ALC come from the power supply rather than the
rig itself. I always thought that was a strange arrangement. Fortunately, I
have a stereo cable with color coded "channels" so it makes connection simple
but would be simpler to run shorter leads directly from the rig
You need a Cinch-Jones S-310 CCT plug and connect the shield of the
alc cable to pin 10. Connect the center to pin 9.
Plug into the matching 10 pin PS7 socket on the rear of the TR7.

Pin 9 of the PS-7 Control connector. The 10 Pin Jones connector. Pin 10 is
ground.
Some day when you're bored, you could go in and link Pin 9 over to that SPARE
phono jack just above it.

I am sure that are at least a few folks who are using the TR7 with a power
supply other than the PS7. And I am thinking of those some are using linears.
So where and how did you gain access to the ALC line of the TR7?
