      Scouters and amateur radio operators--

      For several years, the Jamboree On The Air (JOTA) CW frequency on 20
      meters, 14.070 has conflicted with, and interfered with the
      international PSK-31 "band", also on 14.070. For various reasons, the
      Boy Scouts of America and World of Scouting Movement have been unable
      to officially change this frequency in their publications and
      websites.

      After consultation and agreement with numerous Scout-Hams from around
      the world, it is the consensus that the world-wide Scouting
      membership change the frequency themselves to 14.065. This
      information is being circulated widely through email groups and
      websites.

      The problem is more than the actual interference of CW on top of the
      narrowband PSK-31 signals. Official Scouting publications, national
      amateur radio associations, and official websites all promulgate and
      advertise 14.070 as the JOTA 20 meter CW frequency. Since JOTA is
      only one weekend per year whereas PSK31 is operated year round with
      numerous DXpeditions now transmitting PSK-31, particularly on 14.070,
      the danger is that Scouting will be seen as officially endorsing
      interference, resulting in conflict between other amateur operators
      and Scouting in general. Scouting has received enough black eyes
      without yet another that could have been avoided.

      PSK-31 has grown rapidly in popularity since its introduction about
      1998 due to its simplicity and inexpense. It may now surpass RTTY in
      numbers of operators using it. Due to its very narrow bandwidth
      (31HZ), many signals may operate in the same bandwidth as a single
      SSB (2.5KHZ) or CW signal (300HZ). Within the 2 KHZ bandwidth
      centered on 14.070, it is not unusual to hear 20 to 30 separate
      PSK-31 signals. Yet also due to PSK-31's low power requirement (10
      watts is typical), a single CW transmission may interfere with that
      many QSOs. More information on PSK-31 is at: http://psk31.com/ and
      http://www.kender.es/~edu/indice.html .

      In order for this change to become effective, the information needs
      to be widely disseminated; please post this message to the ham-Scout
      groups you know and feel free to post it on your website. You may use
