QSK With K3 and KW Amp

[Ed G-2]

Hello,
     Is any anyone using one of the old DEO QSK-1500 full QSK switching
units (or the similar PIN diode QSK unit from Ameritron) with their K3 and
external amplifier? I haven't yet received my K3 but I would like to hook it
up with my Heath SB-220 to run full QSK.  I suspect that I will need to use
an external keyer (and not the one internal to the K3) to trigger the PIN
diode switching electronics.  Same deal with software-generated CW.
     If you are running full QSK this way with your K3, let me know if you
experienced any problems setting up the switching, and if you are
successfully running contest/computer software in the CW mode with full QSK.

I've run my SB-1000 with QSK-5 pin diode switch with no problems with my
K3 using the KEY OUT signal.

Not quite sure why you think an external keyer would be required.  I  
use my K3 driving an AL-1200 with an internal QSK-5PC -- the K3 keys  
it just fine, with no hotswitching on either key down or key up.

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,
