[Elecraft] low-noise 40m RX antenna

[Gene A. Williamson]

	I have found a loop to be a good low-noise receiving antenna. Up about
15ft and made of #20 magnet wire, it was nearly invisible. I fed it with
ladder line to use as an all-band transmitting antenna. I would think coax
feed with perhaps a QRP transmatch (if needed) would work well for RX only.

	Before you start climbing trees, try this: leaving the AGC on FAST, lower
your RF gain until the S-meter needle rests at the same level as your
noise. (Easiest done by going past the noise, then cranking the knob back
up a hair.) Your noise will be gone, and you'll still have AGC action on
signals louder than that level. Signals below that level will effectively
sound as though you've set AGC OFF. My S-meter has rested at S5 for years
now, and I'll bet I've made hundreds of QSOs where the signal didn't move
the needle one whit.
