...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,

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.
