[Elecraft] OT: K3 and antenna questions

[David Cutter]

It's temporary, but works fine for now.

I drilled 2 holes in the bedroom wall and slid 2 lengths of nylon tube 
therein, they stick out a few inches outside.  A piece of 450 ladder line 
about 3 ft or so goes from the PL in the rig to a connector block on the 
inside wall and the 2 wires from outside feed thro to that.  Height above 
ground is about 15ft at this point.  One wire goes to the bottom of the 
garden about 3ft up, then thro a rt angle for about 6ft rising to 4ft or so. 
The other wire bends at about 80deg and drops to 8ft at the garage barge 
board, then thro rt angle down between the houses to a tree at the front, 
about 6ft up.  Wire is 20swg SnCu used on several projects.  BTW no rf or 
any other kind of earth on rig.  Occasionally hear US 80m ssb early morning.

No balun; after initial tuning the K3 remembers its settings and changes 
instantly on band change.  I think I asked it to fine tune on a couple of 
freqs but can't remember which.  I'll try this for the cubscouts with longer 
feeder for JOTA and see how it works inverted V style.
