I am not necessarily opposed to other hams using Pactor modes, but the one issue that is consistently ignored seems to be the transmission of fax/image data when using the wide bandwidth modes. If kept at 500 Hz or less, the changes in the rules a few years back finally allows fax/image to used in the RTTY/Data areas. But it does not allow it for any modes greater than 500 Hz such as when using P3.
And just for those who think that I am opposed to being able to send wide fax/image in the RTTY/Data areas, I am most definitely am not. What I would like to see is a return to everyone following the same rules. This goes for other very questionable digital activities in the past few years. Either make it legal for everyone or don't do it. Is that really too much to ask? It seems that it is. Without a sea change at the FCC there is little that can be done about the automated station transmitting over the top of other stations since it was decided many years ago that it was an acceptable tradeoff, at least in part because the FCC at the time stated that future advancement of technology would solve that problem. Pactor operators have at least some of the technology to prevent transmissions on busy frequencies, by the automated station, (especially with P2 and P3 from recent information), but it appears that it is not used that much. Maybe with the change of enforcement leadership this could happen? But it is probably wishful thinking to halt these kinds of scofflaw behaviors. 73, Rick, KV9U kh6ty wrote: > Simon, > > The problem is not with Pactor, per se, but with the arrogance of > those who consider retrieval of their precious email more important > than the QSO that is already on the frequency.
