Hello Dave, Don't sse ypou much anymore on HF WSJT ,changes in antenna?
OK and thanks. I contacted the people in VA and they replied right away. telling me that they had stopped the mode. as a result of this case and I believe a ruling / statement by ARRL ( probably only , no official FCC staements) Very hard to check what is true and false. The stop is TRUE though MT63 or 61 is in use with MARS But MT63 is no SS I believe (not published stepping patterns etc ) 73 Rein W6SZ -----Original Message----- >From: Dave Sparks <dspa...@pobox.com> >Sent: Jun 2, 2010 4:27 PM >To: digitalradio@yahoogroups.com >Subject: Re: [digitalradio] ROS MODEM OFFICIAL GROUP > >IIRC = "if I remember correctly". > >The documentation issue stemmed from someone who complained that PACTOR, and >maybe other digital modes, could be considered "codes or cyphers", and the >FCC ruled that they weren't because they were publicly documented.
