I built an interface, and it works well, but I'm eyeing the Collins phonepatch I have as a replacement.  I don't want to rewire this thing, though, so that limits my options.  I looked at building a hybrid circuit to separate out the mike and speaker components, but it occurred to me that I could just buy a cheap Heath phonepatch to do that.  Has anyone hooked up two phonepatches back-to-back, so to speak, in order to get the mike and speaker outputs separated to send to the computer?

Sounds like more trouble than it's worth, even if it works. If the interface you have already works, then why are you trying to cobble something together that will be a cludge, at best?

Mostly because it won't be a kludge.  The issue I have right now is that I have to unplug the mike and plug in the interface when switching back and forth.  I would gain nothing by using my rig's phonepatch input, as it's merely in parallel with the mike.  Also, my interface weighs only ounces, so, if I put a mike connector in it and switched that, the interface would be bouncing all over my desk when I move the mike.  Being able to use the phone patch switch on my 312B-4 would clean up my digital operation in a lot of ways, but most of all by having a single switch to go between the mike and digital.  Well, we'll see what happens when I can get a Heath HD-15 in here.

Interesting ...

You didn't say what rig you are using, but most modern rigs have I/O ports that bring everything to a DIN plug so you don't have to keep swapping connectors.

Good luck with the project.

Modern?  It was modern in the 60s and 70s I guess.  hihi   Collins KWM-2A with 312B-4 phone patch.  It just seems a shame to have this nice, expensive phone patch sitting here doing nothing.  I realised last nite that I could just send the mike signal from my current interface through it and just use my interface for the speaker signal.  But, I think I'll go ahead and get another patch just to do it.
