To all. Concerning using the K3 with an unmodified SB220.
Yes there is a protection diode in the K3, but consider this; Would you put a >1000 volt spike into the key jack of a radio that cost you >$2000. I would rather eliminate the spike be installing a very cheap 1N4007 or equivalent diode acrossed the SB 220 relay coil instead of putting the strain on my K3 components. Think about it. 73 Dave KD1NA _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
