John, when are you going to give up on this crystal receiver set of
yours and get a decent receiver?

For me, receiving at anywhere near the 0.13 uV receiver threshold is
just too much work. I think they should outlaw any received signal
below 1 uV.

Darn Cecil, quite peeking!

From the crystal silicon in the semiconductors, to the crystaline
structure of the metals ... I just can't get away from the darn crystal
radios! And, alas, I am afraid, these days, the sensitivity of my
receivers front end far exceeds my hearing ... I was just bragging. You
caught me!

But, I can still remember those days when I could pull out a gnats
whisper above ... but then, as I remember, there was far less noise then.
