   ARLB006 NTIA: No Objection to Additional Data Modes on 60 Meters   
      
   In response to requests for clarification from the ARRL, the   
   National Telecommunications and Information Administration (NTIA)   
   has confirmed that it has no objection to the use of a broader range   
   of data emissions by amateurs on the five 5 MHz frequencies on 60   
   meters. ARRL's original understanding was that the NTIA preferred   
   that the use of 2K80J2D emission be limited to Pactor III. The NTIA   
   now says that that is not the case.   
      
   In an e-mail response to ARRL Chief Executive Officer David Sumner,   
   K1ZZ, Karl Nebbia, Associate Administrator of the NTIA Office of   
   Spectrum Management, stated, "NTIA has no interest in limiting the   
   types of emission used by the amateurs as long as the data emission   
   does not exceed the 2.8 kHz bandwidth generated by the upper   
   sideband transmitter." Nebbia referred all further inquiries to the   
   FCC, which "...sets the conditions for use of the five 5 MHz   
   frequencies by the amateurs."   
      
   The requirement of only one signal per channel remains, as well as   
   the prohibition against automatic operation. The FCC continues to   
   require that all digital transmissions be centered on the   
   channel-center frequencies, which the Report and Order defines as   
   being 1.5 kHz above the suppressed carrier frequency of a   
   transceiver operated in the Upper Sideband (USB) mode. This is   
   typically the frequency shown on the frequency display.   
      
   Channel  USB Suppressed Carrier (kHz)    Center (kHz)

   2        5346.5                          5348.0   
      
   3        5357.0                          5358.5   
      
   4        5371.5                          5373.0   
      
   5        5403.5                          5405.0   
      
   The ARRL advises amateurs to operate with care when using digital   
   modes in consideration of the fact that hams are secondary users on   
   these frequencies. See the revised 60-Meter FAQ page on the ARRL Web   
   at, http://www.arrl.org/60-meter-faq.
