[Elecraft] K3 and Heath SB-610

[Alan Bloom]

The SB-610 is not a spectrum scope like the SB-620 so you can't get a 
panadapter display.  I don't know what IF frequency your unit is set up 
for but you'd probably have to change the tuned circuit to the 8215 kHz 
(sorry "kc" :=) IF of the K3.  You likely also will need a preamp since 
I believe the SB-610 was designed to connect to the last IF amplifier of 
a receiver, not the first IF as in the K3.
