well, apart from a fairly small group of dedicated hams, there aren't a
whole lot of guys using anything above 2.4GHZ in the amateur allocations.
So, if we do lose some of those microwave bands, it won't be any great loss
to the amateur service.
I have difficulty imagining who is going to use 240GHZ anytime soon for
amateur purposes?
Not to mention all the other crazy microwave bands we have right now.
I think some more practical frequencies that allow for dx propigation are a
better alternative to bands that are nearly impossible to use for the
average ham right now.
Unless you can build your own microwave transmitter and receiver, and your
own test equipment, and your own antennas, then bands above 3GHZ are
useless.  However, 30 to 70MHZ are quite easy to get onto with surplus
commercial gear and some ham gear.

Speaking of speratic E and F2 propigation on 30and 40MHZ, I used to have a
blast listening to sheriff's departments and other public safety
organizations from the states on my scanner during the sun spot peaks of the
past couple cycles.
I remember during the peak of the second last cycle, I had one of those
preprogrammed uniden scanners where you just put it into scan and it scanned
through all of its preprogrammed frequencies.
Well I nearly fell over when I started to pickup US public safety traffic
like it was down the street.
I had no idea I could get dx on my scanner like that.
Everyday for months I listened to the DC police or something similar...I
never figured out exactly who since their radio codes were completely
foreign, and I didn't have internet access at the time to go look them up...
I am impatiently awaiting the peak of this coming cycle to play around on
those frequencies again.
During the same cycle, I could talk around the world on a radio shack maggy
mount and 5 watts while mobile as well.
