K3: Remote Control Questions
Locked
 
|
After listening to the BS7H pile on 20m's today I was reminded that the
receiver in my 480 is not all that great. Even with the 500hz crystal filter installed, there were all kinds of artifacts from strong stations transmitting up a few khz. So the K3 has grabbed my attention. A couple of questions that are key to remote operations: 1 - I understand that if I short two pins from the ACC connector on the back I can turn the rig on/off. When shorting those two pins is it momentary or constant. IE if I can turn a relay on and off remotely will that relay need to stay engaged to keep the rig on? A little more info would be helpful. I would rather the rig could be turned on with a software command or the wake on serial suggestion made earlier. 2 - I use the sound card on my pc to send receive audio over the internet. Can I send ssb via the pc mono in on the back of the rig. I would assume so since psk is done in ssb.

Speaking of remote control, does the K3 have a watchdog timer to stop
transmission after 3 minutes or some adjustable delay?

Maybe option to stop TX unless keepalive CAT command received in the last x
seconds. While sending the software could send a keepalive message, maybe (for much later) power down radio as well (assumption is that internet connection lost). Also the ability to disable TX via a hardware jumper - radio can be made available for anyone to use for receiving but without the ability to transmit. Later enable/disable transmit via passwords (for the radio administrator). Simon Brown, HB9DRV ----- Original Message ----- From: "wayne burdick" <[hidden email]> > Menu entry; max timeout still TBD.

If possible make the time variable from 0 to 10 minutes. If not
variable a few options would work, say 3, 5 and 10 minutes. I have my 'other' rig set for 5 minutes. I may even drop it to 3 minutes since most of my transmitting is for dx or contests which require short transmissions. If the transmitter drops out due to the timer, it needs to reset itself so one can transmit again without having to reset the rig. Thanks for listening/inquiring Wayne.

I agree... 10 min max should be enough. I use 3 min here without a
problem (but then I'm not long winded ;-) 73, Larry N8LP Richard Thorne wrote: > If possible make the time variable from 0 to 10 minutes.

(b) Provisions are incorporated to limit transmission by the station to a period of no more than 3 minutes in the event of malfunction in the control link. Three minutes seems to be the maximum to ensure that the operator complies with FCC rules.
