      1. optional circuit at the first FF (JP1 pin 2) to drive the board
      with a DDS60. The curcuit needs 50 ohm load, coupling cap, and two
      100K bias resistors to set input at Vcc/2.

      2. PTT out goes 0 to 5 volts. Would like an option for open drain PTT

      3. On-board Xmit LED.

      Some day I would like to see a vfo and phase detector in place of the
      crystals for use with a DDS.
