[Elecraft] [K2] T-R Driver Circuit to key KXPA100

[Heinz Baertschi]

What kind of T-R keying circuit is necessary in the K2 (with K60XV installed
for 60m band usage, no XVTRs connected) to operate the KXPA100 amplifier?

a) Will the XVTR Keyline on K60XV J2-2 / Q3 (2N7000) do it correctly?

b) Is a keying circuit like these necessary?
