You might call that "burly". With the K3 one can key the "relay" jacks of some old amplifiers (e.g. SB220/221) that would fry the circuit in other transceivers. Just don't try it on a Collins 30L1, which is a high *negative* voltage. 73, Guy K2AV On Mon, Sep 7, 2015 at 7:59 PM, Jim Miller <j...@jtmiller.com> wrote: > I don't have schematics for my K3S but going by those for the K3.
