Ok here is more detail ....
Les no problem most probably know of this move from
last year SAME PEOPLE pushing for 90% of the band to
be their own toy ....
50.300 - 54.000 100 khz wide DIGITAL
The people who want this don't care about am FM or
anything else .....
April 2005 ARRL ....
6 and 2 meters: The proposal preserves the lower 300
kHz in each band for narrowband, weak-signal modes
reflecting established practice, but opens the rest of
these bands for bandwidths up to 100 kHz. This is
intended to permit new modes, particularly multimedia.
Did they ask any of us ..... NO .....
The 1st 100 khz is CW which leaves 200 khz for all of
us Very nice of them ......
NOW how did they test this new mode and determin it
would not interfere with the rest of us ?
WELL I ASKED .......
FROM THE ARRL ...
I did a bit of checking. There was a brief xperiment,
>conducted as an activity of the HSMM Working Group,
by one station in Fresno, CA using OFDM with a
bandwidth of 200 kHz in the band 50.3-50.8 MHz, on a
non-interference basis, under an FCC Part 5
experimental icense which terminated in September
2006.
No reports of interference were received.
It does not indicate continuing testing and a 200-kHz
bandwidth for data in the 6-m band is not part of the
League's regulation-by-bandwidth petition... )
You may pass this along to the list if you like.

ARRL Laboratory Manager
ONE STATION CLOSED BAND AND SHORT TESTS
But they saw fit to include it in this proposal . EVEN
AFTER THIS LETTER SAID NO ......
AGAIN did they ask anyone here NO !
