Did I dream this or not, I seem to recall that the government proposed to

I agree about diversity though, some terrible nulls occur just where you
need them to work I understand. its that chap Murphy.

Part of the "digital switch over" will see the radio mic band move
from an analogue system in the TV UHF TV channels to a digital system
in the 1790 to 1798 MHz band. At the same time their status drops from
primary to secondary. What that means is that in the new band the mic
user must ensure he causes no interference to other services. The
current user of this higher band is the Home Office,

Digital switch over is now so close that in all fairness I could not
recommend anyone to but a UHF analogue mic. It would be money wasted.

It's all that is available. But I don't agree that it would be money wasted.
Just keep on using it regardless, there's very little chance of anyone even
noticing that you are using it whatever the official position. That's what
99% of existing radio mic users will do especially as most of them are
totally unaware of any of these proposed changes.

Anyone who goes the official route, using PMSE to find and guarantee
empty channels will be very aware of the situation. I have been
fighting against the move (ok, because I want the digital band they
are moving to) but to no avail. The allocation at 1790 MHz was made at
a European, not national level.


For best advice I would recommend the OP to read an Ofcom statement:

http://www.ofcom.org.uk/consult/cond.../statement.pdf

This lays out the timings and concession on the UHF band.


That paper was pure bureaucratic gobbledegook, a classic bit of moden-day
waffle that said nothing of any help to anyone. Why radio mic users have
allowed themselves to be treated in the shabby way that Ofcom have for years
is a mystery to me.

David.


No clout, I'm afraid. The numbers are just too small. Ofcom doesn't
understand that for each mic in use there are thousands of people
enjoying the result. They just count the units.
