Keying paddle only works on "one side". Bad connection?

[xe1gxg]

Hello!

I have found thatin plugging in my paddles, only the "dit" (left) function works. I used "2.1 Keyer Swap" to check, and same result: only the left paddle activates. I tried a different paddle. Same thing. Tried going from Iambic B to A. I am in straight key mode for now, with my old straight key.

BTW, at one point I had noticed on power up, even without a key connected, a series of "dahs" being emitted for a bit.

thanks for any help
