As I recall from my days of film making with the late Roy Neal, K6DUE, (who
was the person who literally began the manned ham radio in space operations
through his connections with NASA) the reason the frequencies are -- as
they are -- is the result of three years of exhaustive research by the
folks who are responsible for any ham radio being ion the ISS. The choice
was made so that ARISS operations interfere with no-body -- and hopefully
-- nobody on the ground interferes with ARISS.
Changing hats: Since the 1960's I have been researching and writing about
bandplanning -- repeaters -- remote bases -- etc. The first 26 years for
the now defunct 73 Magazine (Looking west) and the past several years for
Worldradio. As such, I have an ongoing information flow that few if any of
And it boils down to this: Not all the world having the same bandplans as
the USA and North America. And the "world" is not going to change to
satisfy a small group of folks who -- now and then -- want to talk to an
astronaut or cosmonaut.
Rather, those interested in such an activity can only perform it because
the rest of the world'a ham radio community permits it to happen. And the
rest of the world of ham radio has -- in a defacto sense -- has dictated to
manned space enthusiasts where they can operate.
The bottom line: Be happy that you can have the opportunity to make these
contacts at all and stop moaning because you may have to twiddle a dial
once in a while. Just consider it as being the way it is -- and the way
its going to remain -- because it is not within any of your power to change.
