I worked with Doc Sheller on the DEO QSK1500 many years ago ...
With the current behavior of the K3's Key Out jack, you should be able to use the "FT-757" instructions in the DEO QSK1500 manual (K3, Key Out to QSK 1500 Amp Rly In, and QSK1500 AMP RLY Out to the SB-200 PTT line). The QSK 1500 will follow keying from the K3 ... If you want to add an extra level of safety, connect a pull-up resistor between +5V and the K3 INH input and connect the QSK 1500 "Pos Key Out" to the INH input of the K3 (close to ground to allow RF). 73, ...
