KX3 is "ON" after AC power outage
Locked
 
|
Have had two AC outages recently and both times my KX3 ... which was "OFF"
... has turned "ON" with the return of power. Everything in the shack is powered by a large Astron PS that runs 24/7 via RigRunner fused Power Pole boxes. . The KX3 comes on in "receive" mode and set for CW. Has anyone else seen this "odd" behavior? 73 - K0PP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Is something connected to the Mic jack on your KX3? Could it be applying a voltage to the PTT line, even if only in a transient manner? Applying a voltage 8-12V for 100ms will cause the KX3 to turn on.
As for the mode it comes back up in, this will probsbly depend on what mode it was in the last time you shut it down cleanly. If you remove the power without shutting down the radio properly, it will not properly save its state at the time the power was removed unclearly. 73, Matt VK2RQ > On 4 Apr 2014, at 8:50 am, Ken G Kopp <[hidden email]> wrote: > > Have had two AC outages recently and both times my KX3 ... which was "OFF" ... has turned "ON" with the return of power.

Hi Ken,
It's possible that the KX3 is getting an outside signal to power on. If you have a cable attached from ACC2 to a device that behaves as described below, it could cause the KX3 to power on. I don't know what device type to suggest, because I don't know your station's layout. From p28 of the Owner's Manual: Remote Power On/Off To turn the KX3 on, a remote-control system can place 8 to 12 volts DC on the mic jacks PTT line for 100 ms or longer. (The ACC2 jacks PTT IN pin function cannot be used for power-on control. Use only the MIC PTT line.) To turn the KX3 off, the controller must send the KX3 a PS0; command via the ACC1 jack (RS232 or USB, depending on the cable used). If the controller also turns off the KX3s power supply, it should first allow 100 ms for the KX3 to shut down.On Thu, 3 Apr 2014 15:50:48 -0600, you wrote: 73, matt W6NIA >Have had two AC outages recently and both times my KX3 ... which was "OFF" >... has turned "ON" with the return of power.
