[Elecraft] K3/Logger 32 Interface issue

[mikefurrey at att.net]

What Mike and Fred said. Also look for cables that are shielded. I 
unknowingly started with a prolific chipset and after loading the driver, 
the laptop with Win7 functioned so bad, I had to reload the OS. I found a 
FTDI unit and it works fine BUT the noise level dramatically increased until 
I replaced them with shielded units. BTW, I have noted that when the 
prolific chipset is used, it rarely  mentioned on the box or by the 
manufacture. I have also noted that when the FTDI chipset is used, the 
box/manufacture always does indicate such! Hmmmmmm ...

My Experiences ...
