There is a problem with these kinds of highly specific "band plans." Most hams will not even be aware of them, nor will they necessarily want to follow them. This is certainly true of hams outside the U.S.
We must not lose sight of the fact that there are now many different users of a much more limited resource and they will have to try and fit in wherever they can depending upon the changing propagation and the other users. For example our state NTS CW nets have all moved to one frequency at 3555 and that is where they will operate for around 5 time slots per evening. In fact, logistically, it would seem that, at times, the NTS nets will take up most of the 80 meter band, from above 3525 to 3600. It is not just the net frequencies, but also if there are any UP or DWN traffic as well that move off frequency. Then if there is a CW or RTTY or other digital mode contest, those operators will be using the entire 3500 to 3600 data/RTTY sub band as they have a right to do. What we may want to suggest is to determine the area for PSK31. What almost always happens is that other modes tend to operate just above that "watering hole" area and then about 10 KHz above that, you often find RTTY. The idea to have sub sub-bands that are specified for specific digital modes is actually poor operating practice due to not using the frequency in an efficient manner. There is nothing wrong with having Olivia next to MFSK16 or most any other digital mode as long as the frequency is not busy. This is a shared resource with no one having exclusive rights to any frequency. I don't see data and keyboarding pushed down very much at all. It depends upon what the operators find is open. Anything below 3580 is going to have a lot of CW. One thing that would help a lot would be to do away with the Extra Class bottom 25 KHz and make it available to everyone, just like it is on 160 meters. But I suppose that would be very difficult to change. I could even envisage making this bottom 25 KHz ultra narrow exclusive, for under 200 Hz modes. Often this 25 KHz is under utilized although perhaps many extra class ops will move down there for causal chats if their friends are extras with the drastic changes coming a week from this Friday. One thing is for sure, having an extra class license here in the U.S. has dramatically increased benefits. And it is not that difficult to get the license anymore with only a written test needed to pass. 73, Rick, KV9U expeditionradio wrote: >Some Suggested Keyboarding Activity/CQ/Calling Frequencies >for the new 80 meter band for USA: > >BPSK31 = 3545kHz USB (3545.3-3548.0 kHz) > >QPSK31/PSK63/125 = 3547kHz USB (3547.3-3550.0 kHz) > >MFSK = 3548kHz USB (3548.3-3551.0 kHz) > >OLIVIA = 3549kHz USB (3549.3-3553.0 kHz) > >PAX/CONTESTIA/DOMINO, etc = 3550kHz USB (3550.3-3554.0 kHz) > >HELL/FMHELL = 3552 USB (3552.3-3555 kHz) > >MT63 = 3553 USB (3553.3-3556) > >RTTY/FSK = 3555+ USB (3555.3-3565 kHz) > >Notes: > >The new FCC subband changes for USA hams go into effect on 15 December >2006. > >On 80 meters, Data, and Keyboarding activity will be pushed down lower >in the band than ever before.
