[Elecraft] K2/100 rtty & microphones questions

[David Ashworth]

Hi to all.  Been reading about this rig and looking on the website, learned
a lot so far.  Looks like a neat rig, especially the receiver.  I have a
couple of questions that you might help me with.  For RTTY, does anyone use
this rig for contests and what is the safe level to run it in a contest
using RTTY?  I see that there are several levels to set the fan at.  Also
for RTTY, does this rig just work in AFSK, or can you make it work in FSK?
Another for RTTY, what add-on modules are you running or would you
recommend?  Now, for the microphones, I assume you need to get the SSB
option.  I have looked at the website, but wonder, is there a particular
spot on the website where the mikes and the jumper configurations that will
work with the K2/100 are displayed?  Thanks for your help, best regards,
Dave, NC6P.
