usb to serial adapter k3 problem

[k6st]

Very strange problem I am having between the K3 and the computer for rig
control using a usb to serial adapter (prolific chip set).  Sometime it
works just fine and other times it goes funky, looses rig control or cw
keying or keying the tx with no power output. When I reboot it sometime
works fine and not other times.

On the elecraft website the  usb to serial adapter they sell is currently a
FTDI chipset as they went away from the prolific chip set.  Last night when
I experience the problem consistently, I was however able to run the K3
Utility fine with now problems to download the latest k3 firmware.

I am wondering if the solution might be to go to another usb to serial
adapter with the FTDI chipset?  Is these a difference between different
brands or models of usb to serial adapter with FTDI chipset?

I also saw online that some people had problems with the KIO3 with in the
K3.  Any ideas of what I am up against or how to solve the problems is
greatly appreciated.

Thanks &  73,

Barry K6ST

I experienced things much the same as you did.  

I went to adapters with the FTDI chipset and have not had any further problems.  I have two different brands.  No trouble with either.

Make sure that you have no RF in the shack. If RF is present, it can enter direct in the
K3 or affect the adapter and create problems, which you have described. So keep the RF of
the K3 and the adapter with torroids on the control cable.
