Watch out using a steady-state meter to measure amplifier 
currents! The 2100Z is a good example of a very odd circuit.

The FL2100Z has positive relay voltage. It has a peak relay 
closure current surge of about 500-600 mA (that settles 
lower) and about 16-18 volts open circuit without much 
backpulse. It should be good for direct keying with the 
Elecraft K3 if the K3 will take 5 amps.

The regular FL2100 has negative relay voltage. No good on 
the FL2100.
