Additional info:
Related documents: NB! There is a manual flying around the internet, claiming it's for IC-21A. It is
also available from Icom's own site. However, it's actually for IC-21 (without A)
which is a bit different in design.

So, if anyone has the version A manual, please contact me so I can upload it here
for the benefit of our fellow hams ;-)
