I can testify that Warren is correct!  I wired a DB9-to-DB25 adapter =
cable for my DB25-to-DB25 radio control cable.  The adapter cable did =
not work. =20

Then I saw Warren's message this evening, swapped pins 2 and 3 of=20
the DB9 and Bingo! The radio and NA talk to each other.  Thanks, =

The OMNI VI Manual is dead wrong on the DB9 pin-out.

used this setup in M/M situations at N2RM, and for FD with WA2SNA and =
