Hi all, Tom mentioned damage to the diodes in his SWR bridge, the possible
damage to the RX front end doesnt bear thinking about. On this front I
recently found a source of the small wire-ended neons that I am sure we all
were familiar with wired across the input transformers of Command Receivers
and the like (I'm showing my age again !!) Neons take a few millisecs to
fire but anyone who has them fitted with be aware of the little flashes with
a non-earthed aerial that occur even when there is not any nearby thunder. I
think they fire at about 70v.

The neons are order code    Z2459    from Greenweld  at £2-50 for 10
from the March 2001 cat.

They often have odd values of high voltage (250V to 1kV) capacitors at
reasonable prices.
