Hi Rye, ah this time its a little different. Its not "two Nations divided by
a single language" this time.....It is the problem with scientific
definition and popular (corrupted) usage ....a "transistor" is an AM
portable radio..actually !!
Paraffin is the general popular term given to a grade of heating oil, and
Jet engine fuel. Where scientifically if I remember my organic chemistry
correctly ..."the paraffins are a family of straight-chain hydrocarbon
molecules" ....cor that was dug up from a long time ago......hope I got it
right.
The Wax is a high molecural weight member of the family usually popularly
called "Candlewax" in the UK.
Its all good for a laugh.
By the way the last time I was at Rugby GBR (16kHz) in the tuning loft, the
tuning-coil/variometer was made of 'litz' the diameter of an man's wrist (I
believe I was told it was 800 and some strands) and it was hung on an 'well
seasoned oak frame' I believe. It was definitely varnished wood, and we were
cautioned that there was not a nail or screw in it. The construction was all
joints and dowels. This was in the early 60s when it was still sending morse
and the TX had not been phase-stabilised. Every time the key went down the
coils 'tensed' like great muscles, and relaxed as the power went off again.
I asked but they did not seem to get trouble with work hardening or fatigue.
I believe the room was shielded by mesh but I cant remember now. Dave has a
way to go yet as they were only running QRP at 500kW. Another 500kW on hot
standby and a third bank was in maintenance.
