I'm copying this to two 160 reflectors because this impacts 160
meter operators and they deserve to know what is going on.
Anyone on those reflectors this discussion is on the MFSK
reflector. Do NOT reply on the topband reflectors, or to me!
Just a fair warning on 160. I don't know who your "experts" were,
but if the notes suggest anything above 1820 and below 1850 in
almost any area of the world you will be right back into having a
problem with people on 160.
As I've mentioned before, 1825-1830 is HEAVILY used for CW DX,
and has been for years. The IARU is totally out of touch with 160
meters, and you will not move thousands of people whose
operating habits are well established just because some people
who never operate the band made a suggestion.
The actual usage of 160 meters is 1800-1810 CW ragchew
operation. 1810 QRP calling frequency. 1811-1825 CW
ragchewing. 1810-1825 Japan's full band allocation (except for a
1908-1912 segment that has little use now) and is heavily used
world-wide at times when it is dark in Japan. 1825-1835 or so is
mostly CW DX world-wide. 1840-1845 LSB DX SSB world-wide.
Digital modes anywhere between 1825 and 1860 or so will cause
As for 40, you are headed for problems there also. MFSK can
simply not decide to "take over" 7035 to 7040 when that area is
heavily used for CW. MFSK would be better placed in or near the
digital mode areas of the band.
All the rest looks good as I can see, but I think forty and 160 would
cause problems as written.
