That's almost right. You cannot use a VGA cable with the Y-BOX or any Elecraft radio because they almost always short too many pins to ground.or to each other.
A straight 15 pin M/F (non-VGA) extension would have worked OK to extend the Elecraft ACC cable. I supply these with the Y-BOX. I can also obtain longer lengths. The Y-BOX transforms standard 15-pin straight cables (not VGA) to KPAK3AUX equivalent, plus some extras like powering on the amp. from a K3 or K4 macro, or optionally opening the keying line so that an external device like a SteppIR controller can protect itself from high power while it is moving. The "Key Line Interrupt" gender changer supplied with the KPAK3AUX cables is not needed with the Y-BOX since that's built into the Y-BOX as a jumper option. 73, Bob, N6TV https://bit.ly/Y-BOX On Sun, Sep 19, 2021 at 5:46 AM Eric Norris <norrislawfi...@gmail.com> wrote: > I must point out that N6TV's Serial and Y boxes can be configured to use > VGA cable between K2/K3/K4 and Elecraft amps.
