Dear EME guys,
Katsuura Dish Experimental Station (KDES) will use the call sign 8J1AXA
for
the operation from the JAXA Space Communications Center, using 18m Gregorian
dish antenna. Station license would hopefully be issued in a few months
first for
a simple small station of JA beginners' size, and then grow up to be a big
one.
It is requrested here in Japan to apply for the station license change on
every
occation when you change main rigs/output power/bands/antennas, which would
use to delay the licensing procedure. So we can not tell you now when we
could
operate EME with full output power on a certain band.
The original JAXA 18m dish is designed for 137MHz and 2.1GHz. We are
desiging
the modified feeds for amateur bands, from 144MHz up to 5.7GHz possibly.
Fortunate enough, it would be very possible to operate with the original
antena configuration 2.3/2.4GHz. For EME use, we have to re-model the
auto-tracking
system from the present manual servomoters. JAXA already removed the
program
tracking system from this antenna, and the high power TWTA, as well.
