"Beware the manual for the AL1200 doesn't appear to mention the change
over timing of it's relay, the K3 outputs RF approx 10 milli seconds
after the linear keying line goes low - measured on mine with a half
decent scope. There is currently no adjustable delay for that timing in
the K3 ..."
I measured the relay switching time of my ALS-600 open frame relay, and it
took 15ms. I replaced the open frame relay with high-speed signal relays
that switch in <5ms and everything works great. But these signal relays are
not hefty enough to handle an AL1200.
