I know the met office needs some info about
activities on 9 Kcs but did not realize it was every second of every
transmission.
I will instead operate from my EU qth where
no such conditions apply. I am not rushing though and will wait until a dozen or
so become active, then I might make a start.
I have all the equipment ready including a 800w
amplifier. I see Chris is using vy thin wire but I have an abundance of 1mm and
2mm enamelled copper wire for the job to avoid heating and
flashing.
This sort of freq needs at least a few hundred
watts and an elevated antenna to cover a reasonable distance, QRP and
earth antenna will not get beyond your front gate, the met office have little to
fear at present.

Yes Mal.
The process is quite simple: we drop them an
email and they (one of 3 people in Exeter) respond almost by return. I have
been pre-booking slots weeks ahead. They also require copies of a log showing
the actual activity so they can check if they were being interfered with (I
book for a day but may only be testing for a couple of hours).
I agree
it is a bit OTT, but never mind.
Have you applied
yet?
