I hooked up the grey PVC base loading coil (30 turns #10 wire, 4.5inch
diameter, 6TPI)  to the 40 foot vertical today; it doesn't get warm at
all at 100W keydown... no arcing, sparking, or other trouble, but the
efficiency hit of such a short antenna is obvious... it seems my 80m
and 160m background QRN levels are about the same on this antenna;
At any rate, the PVC losses seem insubstantial so far.  If anyone
wants to mail me an amplifier, I can test higher power!

Anyway, the point was that something is better than nothing... we'll
see if I can make any contacts, but I've got all of 12 countries
worked on topband, so I'll probably knock down a couple here and there
until I can put up something better.

Thanks for the input on the coil... if I ever do test it with high
power, I'll let everyone know the results.
