A note from Doc  VK6BUG 
Thanks for that info Allan & I have had 3 Simplex units through my hands 
over the years. The first bug I had back in the early 60s was one. Later I 
toted Vibroplex units around the world with me, each at different times, and 
still have 3 of them. Funny, I'm supposed to be a dab hand with the key, but 
I can still only use one at a time....???? Perhaps I should work on that 
deficiency in my armour. Hi Other than polar ships, I served 14 yrs with the RAN as a Petty Officer 
telegraphist, and most of the young coves used hacksaw or ss knife blades 
and the fulcrum unit out of AWA Manipulating Keys to produce what were 
affectionately known as 'sidewankers', probably the most popular key in the 
Navy during 1950-80. I used one on the Murmansk/Greenland/Iceland runs 
often, because it got too rough to operate at any desk or use any other type 
of key, so I used to lie down on the wireless office floor, one leg raised 
up & foot pressed against a bulkhead and the other leg positioned so the 
foot could press against the front edge of the desk. I held the sidewanker 
in left hand round about the abdomen area so that it was free to move with 
the pitch and roll of the vessel, & operated the knife blade side to side 
with my right hand. Otherwise no CW would have got out!!!!Ohhhh the memories!!!!
 OK on not being able to defy gravity with the bikes. Nothing like a 
well-tuned HRD, Matchy or Norton with tuned megaphone barking! Although the 
more modern 1000cc racing Laverda with a similar system also appealed to 
me....... 
Keep up the good work Allan & I might catch u on 160-80 or 40m 
Best regards
