[Elecraft] K3S & K3s with newer I/O board

[William Liporace]

Hi Folks,
I am having an issue with the band data out from the K3s and K3S. Both 
have are basically new. The K3S was NEW in Aug 2018 and the K3s had the 
I/O board replaced at the same time. Both units have the same issue. 
They don't seem to be able to drive band data input of a couple of 
antenna switches. The one switch has a 1K input resistor. If I change 
them to a 100 ohm resistor, they work fine.

So my questions are:

Is this normal?Should the band data work on the newer gear?
What am I missing?
Can someone tell me what to do?

yes, I know about the 2.2K resistors, but should I need to?
