[Elecraft] KX3 production firmware release (MCU rev 0.91) and new

[Lance Collister, W7GJ]

WOW!  That would be a GREAT option!

I just measured the serial output from the USB cable on my laptop, and I have -6.23 
on receive and +6.8 VDC on transmit between the RTS (7) and Signal Ground (5) lines.  
If it would work to simply stick a 1K or 10K resistor in series with the RTS line, it 
sure would be a lot more compact and fit better into a connector than resistors and 
2N2222 ;-)  MNI TNX for all your work!  VY 73, Lance
