[Elecraft] Re: 4 band antenna for KX-1 & KXB3080

[Scott Walker]

Ray:
I appropriated your idea because it seemed elegant, and I also find it works 
FB.  To save just a bit of weight I attached a crimp-on type BNC directly to 
the speaker wires, so I do not need to carry a BNC-banana plug adapter.  I 
wind it all right back onto the plastic spool that the wire came on, wrap a 
rubber band around it, and have a neat antenna package.  BTW, I found out 
the hard way that it helps to wind one leg back onto the spool at a time... 
don't wind them on together or you will spend WAY too much time getting them 
untangled and separated in the field!

In response to the original question about installation of the KXB3080, the 
only problem I had was that I shorted something when installing the module, 
I still don't know what, but I had to take it out and move wires and toroid 
leads around until it was cured.  The spaces are VERY tight.  The symptom 
was much lower power output on 80 meters than on the other bands.
