Sorry to see that Andy,
The metal tape looks suspicious, damage
very intense at the lower far corner , shelf is most
probably heat damage from the fire as under the coil looks
intact ?
I for one will be having a quick look
in the shed, round the 500 atu make sure nothing is 'too'
close

Not sure what started burning, but it was in the bottom corner by the look
of things which is well away from the high voltage stuff at the
top.
The system ran for years using a plastic dustbin as the coil housing, even
at 800 Watts occasionally. But from the way the shelf has melted, it looks
as if the plastic used in those B+Q sheds absorbs RF. Pity, it was
going to house HF ATU

Well, it was nice while it lasted. Went downstairs and smelt
smoke. Heard a crackling noise coming from the plastic "shed"
housing the ATU . Opened the door, saw flames and melted
plastic.
Two buckets of water before they were extinguished - plastic B+Q sheds
burn very well
Goodbye antenna tuning cabin :-(
The loading coil and antenna survived. My credibiilty
didn't :-(
Pictures will follow

Sinece theere were no reports of my QRP WSPR beacon last night two
conclusions can be drawn :
a) No One was listening
b) Its too weak.
To resolve a) ...... ?? Not a lot I can do apart
from post this message :-(
Generating about 600 Watts this will increase ERP into the
region of 17dBm
(The WSPR message says 13dBm, but its lying. I've already run up
and downstairs with the PIC programmer, and don't want to do it
again)
