[Elecraft] K3 power down issue

2014-02-17 Thread Keith Heimbold
I have been trying to figure out why my K3 won't power down completely. I 
currently have it connected to both a MicroHam USB 3 and a Y connector to my 
SPE 1K FA through the ACC. It works perfect when powered on.  But shutdown 
cycle is not so perfect.

The background light doesn't turn off all the way when powering down and stays 
lot without any digits or sound from the receiver. I have been unplugging it to 
turn it off, and I noticed that the last time I plugged the power in it came 
back on to normal operation. 

Any thoughts on this would be great. I am wondering if it is a bad Y cable.

Thanks,

Keith

Keith,

Yes, If you have a VGA Y cable in that cable mix, it would be pulling 
the ACC pin 8 to ground.  That is the signal for K3 Power On - pulling 
it to ground will automatically send a Power On signal to the K3.


You need a Y cable that has all 15 pins connected, each independent of 
each other.  A VGA Y cable will not work because it has pins 6, 7, and 
8 connected together.
