[Elecraft] K3s and DEMI transverter

[W8JH]

I am looking to add the DEMI (Q5) transverter to my K3s and have no
experience with transverters other than the internal one in my KX3.  In the
future, I may wish to progress to 2m EME as well.

Here are some choices I need to make and I would appreciate any advice:

Common IF vs Split IF.  I'm thinking split IF with a K3s?

Common RF or Split RF.  Common RF for one antenna connection?

IF drive level of -20 to 0dBm vs 0dBm to +20dBm.  I think the K3s
transverter output is 0dBm so I'm not sure what to think here.

PTT polarity low instead of high I'm thinking.

High stability Local Oscillator vs. standard.

I could get a custom IF and I think there is some slight advantage to a
14mHz custom but I'm guessing the 28mHz standard IF is good enough?

Thanks in advance for any advice or references.
