We have seen this debate here in Alaska with the '"diehard" (read
this also as the super pro-CW) ham disliking anything dealing with
marriage between the Internet and ham radio. Remote base stations
are a separate case in my opinion. Hams have constructed remote base
stations using all sort of linking technology. I am fine with
this. I am an amateur radio astronomer and quite familiar with some
of the Internet remote telescopes. Its a great way for folks to
participate in activity using equipment beyond their means.
So I have no problem with remote bases linked by IRLB, echolink, or
like technology. As long as any records, contest entry reflects the
actual radio transmitter QTH.
How about a Lunar Remote Base?
