Hi Ron:
Is there any reason to use a keying interface between these
two? The K2 manual says the PA key circuit handles 1 amp at 200v
DC. The LK manual doens't say what the exact specs are, but from the
schematic it looks like the LK uses 12V for the TX relay. I'm an
appliance operator so sure would appreciate advice before I key the
amp direct from the rig.
Nope, none whatsoever... the MOSFET at the T-R output of the KPA100
is more than adequate to key just about any T-R line which offers a
POSITIVE DC voltage less than about 200VDC and 5A... UNfortunately,
it will NOT (directly) key some of the older amp T-R lines which
offered negative voltages.
