Thanks guys.
Yep, I have a cable/plug for the 13 pin jack on the Icom I can swipe from a PSK interface a built a while back (I never got on with that mode). I've been toying with the idea of building a breakout box for audio and whatever else I want to access from that jack anyway, so I may go ahead and do that.
There are 3 small mixers lying around from various band/recording projects, so I can press one of them into amateur service if I want EQ. I really would like to try an EV-635A since the Shark has a noise gate. Once, many years ago, an engineer for a radio station where I was working grabbed a beat-up old 635A from the bag used for high school ball games when the control room mic bit the dust. It sounded really good, I thought-- much like a ribbon mic when you got up in it, and nothing like a '58 or '57. Anyway, I have several mics I can play with, we'll see how it goes.
I had a footswitch for a while, but never liked it as much as I thought I would. Most of the time I have been using the Heil ICM, not because I think it's a great mic, but because it's adequate and convenient. The Heil pistol grip PTT switch seems like a dumb idea, but I like it.
What I may do is wire up one of those painted gray utility boxes from Lowes and use a light switch for PTT on AM. I rigged up one of those that sits on my desk to reverse direction of the 2 element 20m yagi I have up right now.
Thanks-- and if you can think of anything else about the DSP110, please pass it on.
