      Hi All
      Just help shine some more light on the frequency subject, In the EU 40m VFO FREQ is 7039 then set DF to about + 100 or 200Hz to avoid WSPR QRM.
      30M is always given as 10139 but this frequency is almost unusable due to WSPR and PSK stations 10138 is usually clear and I've had lots of QSO's around this spot.
      160m 1838can suffer the same with PSK QRM and its always worth keeping an eye on 1839 it's usually clear of QRM.
      Hope that helps

      The problem here is that there isn't really much agreement yet on the
      frequencies for Data modes, as the band plans between Regions 1, 2 and 3
      can vary depending upon the bandwidth allocated by the various authorities.

      However, here are a few frequencies to keep an eye on...

      Taken from http://hflink. com/jt65/

      JT65A HF Frequencies

      VFO FREQ
      - 28076.0 kHz USB
      - 24920.0 kHz USB
      - 21076.0 kHz USB
      - 18102.0 kHz USB
      * 14076.0 kHz USB
      * 10139.0 kHz USB
      - 7036.0 kHz USB
      - 7039.0 kHz USB
      - 7076.0 kHz USB
      - 3576.0 kHz USB
      - 1838.0 kHz USB
      - 1805.0 kHz USB

      JT65A signal is normally about +1.3kHz to +1.5kHz higher than the VFO
      frequency.



      Terrestrial JT65A
      VHF Frequencies

      VFO FREQ
      - 144.076 MHz USB
      - 144.116 MHz USB
      - 144.160 MHz USB
      - 50.076 MHz USB
      - 50.160 MHz USB
      - 50.260 MHz USB

      As I say, some of the above will be used in some parts of the world, but
      not in others.
