[Elecraft] Amplifiers in general

[Fred Jensen]

One can do this with the NCDXF Beacons ... they change in four 10 dB 
steps, 100 W, 10 W, 1 W, and 100 mW.  No sunspots right now, but you 
might be able to hear one or two of them on 14100.  Most interesting 
thing I notice is, while the 100 W signal may be S6 in S2 noise, I can 
still hear the 100 mW signal which should be 40 dB down [~S0].  The math 
is sound and exact, the reality ... not so much.
