This all reminds me of the very small odd-looking antennas that are I think
still advertized in ham magazines.  They have two bands of aluminum sheeting, a
coil or two I think, and some sort of capacitor to make it all take power, all
the size of a common trash can.  I'm reminded of one fellow who worked out of
his state on a light bulb dummy load hooked up with clip leads.

My ER magazines are all packed (we are moving.. to a small farm in rural Virgina
where the QRM is apt to be very low, hooray!).  Are the Osterwald articles in
ER? Maybe it was HSN. I may have missed the messages that tell where they
appeared.  Bernie, if you have them in digits, I'd appreciate a copy.

My new location will be quite well set up for me to at least attempt to make
careful measurements on my receivers. I look forward to that.
