Re: [Elecraft] KX3 Power On Function and Firmware 1.61

2013-10-25 Thread Charlie T, K3ICH
Personally, it is a small price-to-pay for not accidently running down my 
internal batteries when carrying the packed radio.


You can even choose which two fingers you want to use too.

Subject: [Elecraft] KX3 Power On Function and Firmware 1.61


I use my KX3 only in a fixed environment.The need to push two buttons for 
Power On can be rather clumsy.Can see need in portable op but is there a 
work around for just one button Power On operation?
Also I installed firmware MCU1.61/DSP1.23 .For those who use AM,which is 
probably few, the firmware now makes AM transmit useable on the KX3.Thanks 
Elecraft!!

Cheers..Larry

If you don't mind a little bit of external hardware connected between the Mic, 
and radio, you can power up a KX3 by applying a +ve voltage to the Mic PTT 
line.

From page 28 in the user manual

Quote
Remote Power On/Off
To turn the KX3 on, a remote-control system can place 8 to 12 volts DC on the 
mic jack´s PTT line for 100 ms or longer. (The ACC2 jack´s PTT IN pin function 
cannot be used for power-on control.  Use only the MIC PTT line.)
UnQuote

To power it down, you still need to press the two buttons, or send it the 
remote 
command 'PS0:' on the serial remote control port.   But see the note about 
letting it shutdown, before turning off the power supply feeding the rig.  (Not 
a 
problem if batteries are fitted I think.)
