[TenTec] Any QSK experts here?

[Bill Tippett <btippett@alum.mit.edu>]

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.
