K3 and Ameritron QSK-5 Connections and Settings

[Chuck - AE4CW]

I've found several posts regarding this combination but would appreciate a little more information from those who are successfully using it:

1) Which connection are you using between the K3 Key Out and the QSK-5?  Key 1 or Key 2?
2) If Key 2, do you have a jumper from AUX to Key 1?
3) Any other connection configurations you are using or have tried?
4) Any connection configurations to avoid?
5) What CONFIG: TX DLY setting are you using (8 ms default)?

For reference my amplifier is an AL-80B.

Thanks for any feedback!

Chuck, AE4CW

Chuck:

Keep this in mind.  The QSK-5's "KEY 2" line activates the PIN diode
circuitry.  "KEY 2" activates the QSK-5's input and output relays.

> 2) If Key 2, do you have a jumper from AUX to Key 1?

Ideally, you want to jumper KEY 1 and KEY 2 together with a "Y" cable using
steering diodes.  Then, the RELAY line from the QSK-5 connects to the
Ameritron amp.  If you use AUX to activate KEY 1, that adds > 1 msec. of
additional delay to system timing.  AUX is primarily used for TX INH
handshaking between the amp and transceiver.

This PowerPoint presentation from N6MW is essential to ensure a proper
interconnection between the QSK-5, transceiver, and amplifier:

Paul,

 

Thanks for the lead to N6MW’s PowerPoint.  That has been invaluable!
