How do I turn OFF my K3 remotely
 
|
Can someone tell me how to turn OFF my K3 radio remotely through HRD.
All I could find in the archives was this simple statement. From HRD If one wants to get fancy, you can even shut down the K3 using the Power off command through the serial communications port, and then shut down the computer too. Well no other explanation was given. So that might be fine for some computer expert but doesn't tell me anything other than yes it is possible. Can someone point me to a step by step instructions on how to turn off the K3 radio by remote?

John,
I don't know if or how that HRD does it, but remote power off is available if the software issues a PS0; command to the K3. Note that a powered off K3 is not listening to commands, there is no way to turn the K3 on via RS-232 command. To turn the K3 back on remotely, an external device must pull the ACC connector pin 8 to ground. That may require additional hardware at the remote site. 73, Don W3FPR On 10/24/2014 10:33 PM, John K9UWA wrote: > Can someone tell me how to turn OFF my K3 radio remotely through HRD. > All I could find in the archives was this simple statement. > > >From HRD If one wants to get fancy, you can even shut down > the K3 using the Power off command through the serial communications > port, and then shut down the computer too. > > Well no other explanation was given.

John
You can send the PS0 command from HRD: Macros>Display>CAT Comands ( PS0). You will hear that the K3 audio stops and you can then switch OFF the K3 by briefly shorting ACC pin 8 to ground. I use GSM SMS to do that (and subsequently to switch OFF the PSU). An IP power switch may be simpler, but I like to be able to switch everything OFF also if my router goes dead. One slight problem is that you need to be sure that pin8 has been grounded and the K3 has been switched OFF before you switch OFF the PSU. I do that by very carefully listening to the audio (Skype or IP-Sound). But in some cases there may be some delay in delivery of SMS and it may be difficult to ensure that pin 8 has really been shorted ( and you may want to request the relay status by yet another SMS!) But there is a very weak change in the audio noise level when pin8 is pulled to ground and when you hear that you know you can safely switch OFF the PSU. If someone from Elecraft reads this, I suggest to include in a future firmware upgrade something which makes the K3 audio make a beep when pin 8 is pulled down and K3 switches OFF. 73 Paul/OZ4UN > Den 25/10/2014 kl. 04.56 skrev "Don Wilhelm" <[hidden email]>: > > John, > > I don't know if or how that HRD does it, but remote power off is available if the software issues a PS0; command to the K3.

Thanks to Paul and Don problem is solved.
From HRD hit MACROS>Display>CAT and add the definition and the command PS0 in HRD it automatically adds the ; semicolon to the macro. I already have on the computer an N8LP USB to analog relay board that switches some antennas and has one button to TURN ON the radio by grounded briefly pin8 of the ACC socket.
