      Hi Alex,

      Thanks very much for the kind comments, really appreciated.

      I know how busy guys like you and Tony are, so it's my way of making a little contribuition for all of the fun and enjoyment I am having playing with the SoftRock's.

      p.s. Glad I got some of the answers right!

      73, Bob G8VOI

      > 3. Do not use the "Rocky" D-9 connector when you are using the UBW for PTT keying. In fact, you should unplug any serial cables connected to the D-9 connector. Otherwise there may be problem with the Rx/Tx switching of the Mobo v3.6. The PTT signal comes from one of the i/o pins of the UBW.
