I saw 2 guys do that at ARRL Field Day one year and bring up the local 2 meter repeater for a short QSO off of a small tree. Pretty wild!

Terry,
Thanks for the label!
When I mentioned using a 14-pin IC socket cut in half, I should really have
said "cut into quarters", meaning cutting across through pins #4 & #11, and
being cut lengthwise right through the middle (and trimmed as needed to
yield 4 socket sets of 3 pins each).

Hee, good one John,

Label attached.   Printing it on colored paper makes it look much better
than on
white. I like yellow (no surprise there :o) but some builders have used
other colors.  Light gray and light blue both look very nice too.

Terry,

This little pig went to OzarkCon,
This little pig stayed home;
This little pig ate roast beef,
This little pig had none.
And THIS little pig went whee, whee, all the way home, was fed a proper diet
of
juice (the 12VDC kind), and her voice was heard throughout the land ...

Suckling pig #178 exited the mailbox in Gnadenhutten OH on Friday March 08
2013
and the appropriate slap on the backside (with a soldering pencil, of
course!)
will commence in the very near future.

I would appreciate a label if possible; March 2013 would be fine.

Thanks also for all the crystal socket ideas.  A 14-pin machined pin IC
socket
could be cut in half at the center pins, yielding four 3-pin sockets ...
just
right for one rig if the center pin of the 3-pin socket is used for ground
as
per some of the ideas and pics at
<http://www.w5usj.com/images/bandchangemods.pdf> and
<http://www.w5usj.com/images/crystalgrounding.pdf> ...

Now back to tending the suckling pig ...

Well, of course you'll get different opinions from different people and this is just mine.ï¿½ Some folks think the antenna will set the tree on fire!

I've had both insulated and bare wires in contact with limbs, leaves, etc.ï¿½ Hard to do otherwise on my lot if you want an antenna of any length.ï¿½ Sometimes the limbs or trunk will even grow around the wire.ï¿½ I guess it's possible there's some signal loss, but I don't think it's significant.

On VHF and FM broadcast, there's no doubt that summer foliage degrades reception in fringe areas.ï¿½ï¿½ But being fringe probably means the signal is passing through *lots* of vegetation on the way.ï¿½ I haven't seen any authoritative info to say that this is an issue at HF.

Hi,

The pig rig is cool and has generated a lot of enthusiasm. It's a single
frequency rig. I have come to appreciate single *band* rigs and even
single *mode* rigs for their no nonsense, no compromise performance
along with separate TX/RX. I can see that the pig rig has it's own "no
compromise" performance related directly to it's single frequency
design.

Maybe I'm just dense but I don't understand why anybody would want to
compromise that. And..wouldn't it be cheaper and easier just to build a
multi-frequency rig right from the start with a VXO, VFO or DDS?

The crystals are spaced at .200", but the problem is the "individual crystal" leads are spaced at .200" apart and a dip socket spacing (one side to the other) is .300"

You might use a "wire-wrap" socket which has longer pins and bend them to fin into the .200" spacing thus adapting the crystal lead spacing to .300" allowing crystals piggy-backed (no pun intended) on a dip socket to be used.

Excellent idea about putting all crystals on one dip socket then rotate socket to swap frequencies.

Looks like a perfect cloths line. Even though a little high but could work just fine. Might have to try one with some #10 and wooden fence poles with an insulator in the centre and compare it with a loop and also use it for hanging out cloths.
