      Time for another tutorial, as I've been seeing a
      LOT of confusion on PJ about how this is done.
      And if you don't do it exactly according to this
      protocol, a QSO is unlikely to result. This step-
      by-step assumes use of the 6-meter band. The
      same protocol applies on 2 meters or any other
      band.

      (1) STATION A (W1ABC) calls "CQ W1ABC D6".
      He is running SPLIT right now, transmitting
      on 50260 but listening on 50254. He is NOT
      listening to his transmit frequency (50260).

      NOTES:

      (a) If W1ABC has 2-receiver capability, he
      MIGHT be listening to both frequencies
      in order to possibly catch a caller who
      isn't following this protocol correctly. DO
      NOT DEPEND ON THIS. FOLLOW THE
      PROTOCOL DESCRIBED HERE.

      (b) The "D6" goes AFTER the call sign. This
      is important. See the explanation in the
      final paragraph below.

      (2) STATION B (K4DEF) hears W1ABC's "CQ
      W1ABC D6" on 50260 and knows that
      W1ABC is listening on 50254, and that
      50254 is going to be the QSO frequency.
      Therefore, he QSYs from 50260 to 50254
      and calls AND listens for W1ABC on 50254
      SIMPLEX.

      (3) W1ABC has been listening on 50254. If he
      hears somebody trying to call him on 50254,
      he KNOWS that person is now listening on
      50254 also, because according to the
      protocol, if the responding station is
      transmitting on the D6 frequency, he is also
      LISTENING on that frequency. See Step (2)
      above. Therefore, W1ABC switches
      immediately from SPLIT mode to SIMPLEX
      mode on 50254.

      (4) If W1ABC (now on 50254 simplex) decodes
      K4DEF's call sign, he responds with sending
      the Tx2 message on 50254, and the QSO is
      started. If W1ABC knows somebody is calling
      but doesn't have K4DEF's call sign yet,
      W1ABC changes to calling "QRZ W1ABC" on
      50254. NOBODY IS NOW TRANSMITTING OR
      LISTENING on 50260.

      That's it. In other words. the calling frequency
      (50260) is used ONLY for calling CQ. Once
      anything is heard, ALL TRANSMITTING AND
      LISTENING switches to the UP or DOWN
      frequency. The only person who EVER sets up
      to operate in SPLIT mode is the station who is
      calling CQ, and he exits SPLIT mode as soon as
      he hears anybody trying to call him, EVEN IF he
      doesn't know who it is yet -- because he knows,
      according to this protocol, that the calling
      station (whoever it may be) is listening on the
      offset frequncy, not on 50260.

      One final note, which has been documented
      elsewhere but bears repeating: NEVER respond
      to a CQ by transmitting the Tx2 message.
      ALWAYS respond to a CQ by transmitting the
      Tx1 message. Make sure that WSJT is set up to
      transmit Tx1 by looking to see which radio
      button is marked.

      If the station calling CQ has formatted his CQ
      message incorrectly (such as by calling "CQ D6
      W1ABC"), and the station who wants to call
      W1ABC double-clicks on W1ABC's call sign, WSJT
      will automatically (and incorrectly) set itself to
      transmit the Tx2 message. You must then
      manually correct this by clicking the Tx1 radio
      button. Just be aware of this WSJT idiosyncracy
      and be prepared to override its choice if it goes
      to Tx2 inappropriately. And ALWAYS format your
      offset-method CQs correctly, as shown in Step (1)
      above.

      Thanks Bill for that tutorial. I like to use the U/D method seeing that it then allows both stations to use Sh msgs while fishing for random contacts which is

              Hi Jerry,

              I was using my 7 element WA5VJB cheap yagi I use for satellites and I
              was able to get some copy on SSB, and Q5 copy on CW. No chance of a QSO,
              but still pretty neat. I didn't get on on Sunday, too busy with other
              things.

              I'll be posting a video including the sound files to my youtube acct at
              some point, once I figure out what I'm doing. (Just got a video cam,
              learning how to edit video :)
