Hello again. Not forgotten... Still doing other stuff but I try to return to
this especially as colder nights mean less chances I'll want to spend hours
in the dark on open land messing with long wires...

While looking at your JPG with the loop design I did an entirely gratuitous
bit of graphic editing because I find bright backgrounds hard to handle when
lookign at things for a long time. Do you want a copy? If so, let me knwo
where I can send it..

I notice you mentioned a 'pancake' or 'solenoid' choice of coil that partly
answers the question I asked on the 16th, but I'm not sure what the
difference makes, and there is also the possibility of winding a flat spiral.
What difference do these variations make on reception? Also, is there a
specific advantage of the spaced turns (solenoid, as used in your design)
rather than making a simple circle of windings, that overcomes the
inconvenience of what is a fairly fragile and awkward shape to carry on foot
for long distances? I'm looking for some advice on this because even though I
can build this as it is, I want to try to organise the order I do things in.
I'm still workign on my beverage reel thing, had to wait for a drill that I
just paid for and started using only last night.. It also means I should be
able to build other things now.
