[Elecraft] K3 - remote power on

[Robin Moseley]

Hi folks.. 
what do people do to switch on their K3  when used remotely? 

up until a recent firmware upgrade, I could leave the K3 switched on and power down the PSU,  when the PSU was powered up, the K3 would come alive all by itself.  Shame that this behaviour has been changed,. 

After installing the latest fimware, this no longer happens,  I remotely shut down the PSU, but when powering back on, the K3 stays off.  Reading the manual shows that  I could provide a ground to pin 8 of the ACC port to power up the rig,  am looking for a low cost way to do this,  so far I am thinking of a cheap USB relay device that I can send a pulse to from a batch file.
