Yes...there is more leeway on SHARES and MARS because they are not controlled by the FCC. But other NGOs are and they can for the most part only use USB...no other mode.
Thus for the NGOs to use other modes, they must rely on the ham bands where their operators can use these data modes.

MARS is using just about every FEC/ARQ protocol common in the U.S. In MARS CW, it long ago was obsoleted. RTTY has not officially been obsoleted, but is all but gone. In MARS AMTOR/SITOR is still seeing use, mostly in FEC, but fading away. PACTOR I, GTOR, CLOVER, PACTOR II and PACTOR III in that order see the most use via commercial TNC/Modems. Next comes MIL-STD-188-110x modems and various wave forms. ALE and AQC-ALE acty is ramping up and thus more use of the ALE DTM and DBM protocols. Both SHARES and MARS will be moving more to ALE network operations and to full STANAG 5066 in time as are all U.S. Government agencies and supporting entities. /s/ Steve, N2CKH/AAR2EY At 11:39 AM 12/14/2006, you wrote: >Doc, > >The problem with SHARES, MARS, Red Cross and other NGO disaster >operations frequency/spectrum assignemnts is that the assignments >say what type of transmissions are allowed.
