That's interesting about the tape. [...]
That was my first thought to check the colour, unfortunately the colour
itself did not degrade. It was the blue tape, and the blue tape does not
lose the colour as easily as for instance the red one sold in Poland
(which becomes almost white when used outdoors).
John's suggestion to look or hear (or smell) the corona, is also a
good idea, but then we need also to ask the experts if it's true that
there is always UV radiation associated with corona. I don't know
enough about it myself.
I don't hear nor see nor smell the corona and - believe me - I have my
eyes open for such anomalies. Anyway, I have the new coil ready to put
on the roof. I will try to shield the TX as well.
The open question is whether high voltage wire itself may cause UV
radiation, even when the voltage is too low for more spectacular coronal
effects to become noticeable.
