An opinion by the party petitioning the government doesn't necessarily
make it a true fact.. Regardless, we US hams are limited in what we
can do on HF for data (if not video) be it bandwidth or bauds or
signal rates. The answer #1 to the 3 part quiz from yesterday is
exactly this. The SCS Pactor 4 Dragon TNC is not allowed under US
It would be cool to use this new software from SCS and do UUCP...
"just in time for the new Dragon PTC from SCS you are welcome to try
the new Dragon Beamer,
a very simple method for robustly (CRC Hostmode) transferring computer
files via HF or Packet."

Not the forget the whole reason I brought this up - we hams should be
making a case to the FCC (and even ARRL) for these better technologies
instead of trying to get a bigger antenna and annoy the neighbors...
