Ok, I've replaced the BNC with an SO-239, and that is working a lot better. CW, though, is a problem. I had originally wired it for straight key, but decided to try wiring it for paddles instead. I added the 2.2k and 10k resistors, put them in the line as shown in the schematic, and connected them to the key socket. (I use W0EB's little breakout boards for this. Much easier to get at the thing.) Problem is, I STILL don't have paddle functionality. It's only operating in straight key mode.
I looked through everything, ran through the menus, and didn't find a place to change the hand key/paddle mode -- I gather that's in a different firmware set -- but I thought that it would work automatically once the voltage divider was in place. It's still only working with the sleeve connection for dah. I need to open it BACK up and start chasing things with the ol' multimeter, but if anyone can think of something specific to check, I'd appreciate it.
This is a v3 board, no mods. I hadn't gotten around to modifying anything since I thought I'd blown it up. If I MUST, I can operate it with a straight key, and maybe even a Cootie, but it seems very squirrelly with a Cootie -- noisy, lousy contact, that sort of thing, even right after cleaning the contacts. I hit them with Deoxit regularly and pull a piece of paper through the contacts to take off any corrosion or tarnish.

Who has to stop fiddling with gear and practice CW more...L2 class on Monday!
