...how do you key the rig? Just set up your software for DTR/RTS via the
COM port...
Yep, that's the way I do it. Works for digital, CW, and FSK.
Some questions about keying the K3/KX3 for FSK:
1. Can someone post a schematic of what this (second) cable looks like
(connectors, wiring) for
Rich - Thanks. The was really helpful.
Wayne - Could FSK control be added to ACC2 GPIO (like K3 ACC DIG0) and PTT
toggled via the microphone connector, thus both available simultaneously to
external RTTY software?
I'm new at this, so apologies if I've proposed something stupid...
/eric,
Capacitor type change was mentioned on the KX3 Yahoo! Group:

Beware buying a used Radio Shack 22-507 supply:
July 2, 2008
*RadioShack Recalls Power Supplies Due to Electrocution and Fire Hazards*
WASHINGTON, D.C. - The U.S. Consumer Product Safety Commission, in
cooperation with the firm named below, today announced a voluntary recall of
the following
Based on this QST 2007 review, it was a noisy switching supply at one time.
I understand the manufacturer made a capacitor type change, circa 10/2008,
but personally I would like to see a QST retest of this supply (or similar
spectrum analyzer plots) before purchasing this supply.
Nice! Room for other things (external battery, dipole, logbook) and lunch!

Ha! I already bought one of your enclosures for the DL1 dummy load. Great
to know there's one for the AT1, NGEN, XG2 in addition to what's listed on
your site. I'll email you about price.

Has anyone crafted a case for the AT1 Step Attenuator?
(and how /do/ you make nice small rectangular holes for switches)
