There is nothing there that is harmful to CW in the least.


Imagine this. Imagine all the CW and digital NTS traffic nets that now
operate in the 150KHz between 3600 and 3750, relocated down to the 75KHz
between 3525 and 3600. Imagine all the PSK and RTTY operators also
relocated down there. Imagine the Canadian SSB nets migrating down
there to avoid the US extras and Advanced. Imagine the folks already
operating there welcoming them with open arms --- NOT!. Then imagine
it is a domestic contest weekend, like SS or FD!

What could be the harm to CW?

In a sense the 3600Khz "band edge" simply "aligns" the traditional 80M
CW operating space with those spaces on 40 & 20. Both of which are
~100Khz wide as will be the case on 80. The sky never fell on 40 and 20
CW and it won't fall on 80 CW either.

Good try, Sir, but no cigar. It's not only about CW.

On 40 (including the latest change) CW/rtty/data get 125kHz (42% of the band)
On 20 CW/rtty/data get 150kHz (43% of the band)
On 75/80 (the widest of the three bands in your "alignment" comparison) CW/rtty/data get a mere 100kHz (20%) of the band.

If you consider the ~42% on 40/20 as a "fair share" for CW/rtty/data, then 42% on 80m would put the CW/rtty/data "band edge" just above 3700, fully twice as much space as this partially-baked R&O gives them.

Even K1ZZ could have put a better spin on this than you and the lady from Michigan are doing!

Apples and cumquats, Brian. Do ALL the math.....

80m 3.5-3.6 CW/rtty/data = 100kc
40m 7.0-7.125 CW/rtty/data = 125kc
20m 14.0-14.15 CW/rtty/data = 150kc

The raw numbers don't mean a thing without taking into account the
other differences in the three bands. Specifically the differences in
the volume of activity per Khz per hour. Doesn't take much tuning
around the lower 100 Khz of each of the three bands to come to the
conclusion that the overall levels of activity on 40 & 20 are some
multiples of the level of activity on 80 and it's been that way since
before Hector was a pup. For the most part 80 is a great place to
indulge in pleasant in-country ragchews because there's seldom any DX
cw, DX SSB or foreign broadcast activity audible on 80 vs. all the QRM
40 & 20

So on this basis I'll stick: The little amount of 80M CW and data
activity which is found now above 3.600 will easily fit below 3.600 if
they chose to move and they'll still have more "elbow room" than we've
ever had on 40 & 20.

And no I'm not bleeding for the CW traffic nets either, they lost their
relevance on VJ day.
