Re: Re: Satellite Idea


You have made a good argument.  If we give in to encroachment of our
frequencies, where will it end?

My previous comments were motivated toward protecting the satellite uplink,
and not considering the ramifications for our allocations.  I can offer no
solution [short of war...just kidding].  It really is out of our
legislature's hands as this is international in nature, so it falls into
relations between gov't state dept's [yeh, don't hold your breath].

But is doggedly using frequencies that are so impacted to render the
satellite unusable going to be the best approach?  This is the crux of my

My opinion is that it is "day-late" to protect 2m.  Utilize the microwave
bands now before they are likewise taken.  As you have heard it often
stated, the microwave bands are a natural place for satellite operations.
I am in favor of doing everything to promote their use [and for AO-40 it
has defaulted to what is available].  So maybe we can use mode-VX on a
trial basis to see the degree of the problem, and if very bad then I
suggest moving on to US and LS entirely.

As I read my trade magazines filled with 2.4 Ghz spread-spectrum data/ISM
articles and equipment ads, I wonder if that, too, may be too late?  At
least by using 1268 and 2401 on AO-40 we are staking a claim for the future.

PS: It may fall to hams in the countries with the pirates to wage the main
battle.  The Int'l ham community can support as well as possible!
