[Elecraft] Article: "Exploring the World Below 530 Kcs With a K3"

[Joe Subich, W4TV]

Wayne,

With the recent FCC announcement concerning the potential for a
sliver band at 137 KHz, would converting the .500 - 2.00 MHz BPF
in the KBPF3 to a LPF provide enough improvement in sensitivity
to make 137 KHz usable?  Might adding 500 - 1000 pF to C6 improve
the situation below 500 KHz (I don't suspect a slight loss of
sensitivity at the high end of the broadcast band would be a great
problem since one tends to run the attenuator there anyway).

73,

    ... Joe, W4TV
