Hibernation here Ralph, although I did pump the dish up to full
height and could hear a sniff on KBQ on 3cm, plus lots or nice fat
aircraft scatter. Then the dratted thing froze wolid, so I had a
lot of fun with gallons of hot water and a pump-action pistol
trying to unfreeze it in the pitch dark at 1.30am.
I've got the heater on in the machine shop and I'm making a batch
of Rexolite lenses for QO100 antennas and three 3.4GHz feedhorns
and a pile of stuff for 122GHz, oh and a 24GHz milled waveguide
preamp enclosure and three 24GHz milled copper PA enclosures and
some DF9IC spreaders and several W6PQL spreaders and some
heatsinks for 70MHz PAs and about a dozen other projects, include
two 500W 23cm PA enclosures to complete. Keeping busy, but I've
dome something hideous to my left shoulder so I can't lift
anything, which means zero chance of getting the SCAM which
supports the 70/23/13cm stuff back up to vertical until a squad
arrives to assist.
All of which means I haven't been able to ask any daft questions
I could ask "What is is like when you are pumping up a SCAM12 and
you realise too late that the heavy power feed cable is caught
round your leg and you can't reach the air tap fast enough to stop
it and your leg is so far off the ground that you are doing the
splits and there is nobody at home or within yelling distance?"
However, I now know EXACTLY what it is like. I had visions of
being found the next morning, hanging upside down by one leg.
Now luckily, I am possessed of an immensely large amount of
gravitational attraction to terra firma. Swiftly and with amazing
dexterity, I wrapped the other feeders round my good arm and
pulled like hell. That just balanced the 22psi air pressure from
the compressor regulator. I managed to pull the thing down about
3ft, but the additional area of the next piston was too strong.
No hope of reaching the tap, even with my bad arm, but I gained a
tiny bit of slack and I managed to shake my airborne leg enough so
the lasso loosened a bit. After a good five minutes of vigorous
wriggling and calisthenics, involving the cable snagging on my
boot and a lot of expletives, it let go.
Now I just had the issue of the feeders around my arm with a pull
of at least half my weight. If I let go, the pressure would
launch the dish and top sections into space for sure. I could
reach the tap, but needed two hands to disconnect the air line. I
decided to wrap the feeders round my leg again, but in a spiral,
and trod on the feeders with my other foot. That let me unwind my
now numb, cold and white arm. Once the blood returned to the poor
mistreated limb, I released the feeders gradually and the dish
went up nice and gently to full height.
That four-strand sinnet plait cable grip I made from Kevlar
braided rope is REALLY strong.
