OFCOM and programme makers

PMSE users will still have access to 700MHz spectrum after 2020 here in the UK according to OFCOM.

"We believe that continued use by PMSE services is likely to secure the optimal use of this spectrum and maximise the benefits to UK citizens and consumers."

Well, they have to earn a crust at OFCOM. Darn quangos!!

More from OFCOM

OFCOM has allocated new spectrum for programme makers and special events. I suppose we should be grateful that OFCOM has done something useful.

A VHF/UHF DX mode waiting to be discovered?

There is some indication that the long Europe to Japan path on 50MHz in the summer months is due to Polar Mesospheric Summer Echoes, or PMSE for short. Echoes of 224MHz radar in Norway suggest strong reflections, so I wonder why more radio amateurs are not trying for 2m DX using these mesospheric clouds?

See http://www.eiscat.se/raw/pmse.html. It is very likely these clouds and noctilucent clouds are the same phenomenon.
