I posted this on the Orion reflector but thought I would try here also.
I finally decided to hook up my QSK amp to see how it works with
Orion. Amp Supply uses a vacuum relay, driven by KEY IN from a keyer and
then connects the amp's KEY OUT to Orion's AUX I/O PTT line. I assume this
is done to insure that there are no delay issues. I did adjust Orion's CW
QSK Delay to 6% which sounds better than 0% in the monitor, but I suspect
there is a better way to adjust this.
Orion recommends doing it the other way around, i.e. key the radio directly
with the keyer, send TX OUT 1 to the amp's KEY IN, and then send the amp's
KEY OUT back to Orion's TX EN 1.
I haven't tried the second way, but does anyone have an opinion as to which
is best, and how to adjust CW QSK Delay? I last used QSK with an amp in
about 1960 using the EF Johnson T-R switch, so I'm out of touch with how
these things work these days. I'm still inclined not to use QSK in
contests for reliability reasons (you only get so many relay cycles in a
relay's lifetime) but may play around with it a bit for DXing.
