[Elecraft] K3 Key Out Problem

[Don Wilhelm]

Gerry,

What are you using to measure the KEYOUT line?  In CW, it will follow 
the QSK keying. so it will be a series of fast pulses.  If you are 
trying to measure with an ohmmeter (or voltmeter), it may not respond 
fast enough to see it on the meter.
The fact that it works when you key the microphone indicates that it is 
working.

Whether your RX antenna is fast enough to follow the K3 keying is quite 
another matter - if it uses a relay, it may not be fast enough.

There are K3 menu parameters that will change the Delay time, see the TX 
DLY menu listing for details.

73,

I recently got a receiving loop antenna an connected the keyoutput from the K3 to shut the power off to the loop when transmitting.  On SSB in works fine when the mic is keyed. When operating CW it does not give an output to shutdown the power. Any help appreciated.
