I have connected a CAT to my IC756 (regular one, non-Pro) and it works fine changing QRGs from RMLog but when I am going to set up CW memories for contests it claims that:

"THe selected transceiver isn't supported for CW Keying"

I suspect that no way to use it with my rig am I right?

You will need an external keyer.

Cool, which are the external keyers that RUMLog supports? (in addition to WInkey or Microham), thanks

WinKey is state of the art.

Thanks, unfortunately they do not sell anymore to EU or UK due to customs restrictions so I will have to see other options compatible with RUMLog.

There are a lot of Arduino clones out there.
