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. Paul WD8OJL
"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 ??" _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
