Subject: RE: [Elecraft] Amp keying circuit K2

Maybe you can key a TIP31 or 32 Power transistor from output of K2 circuit. These worked pretty well for me back in VIC20/RTTY days for keying FT101E.

"The FL-2100B pulls 20v on its keying input, whilst the circuit for the K2 is
only designed for 5-12v !! This is clearly written on the instructions with
the circuit, which I neglected to read. 

Does anyone have details of a simple circuit I can build, so I can use this
with my FL-2100B ??"
