I just installed the keyer in my 9030. While I had the soldering iron out to
change the jumper to Curtis B, I modified the board to re-wire the paddle jack.
With an Exacto knife, I cut the two traces between the connector and the dit
and dah input pins on the chip. Then I soldered two small jumper wires to
"criss-cross" these leads.

Although the accessories (at least the ones I bought) are functional, I'd have
to agree that the construction quality was lacking. The soldering on the keyer
board was really sloppy (sloppier than mine!). A while back I bought the
filter board for my 9040. The mounting holes didn't line up with the
stand-offs in the rig, so I had to work the board over with a reamer to get it
installed.
