73, -Web Williams in Myrtle Beach, SC

Hello and thanks to read this post.

I'm having some problems to monitor
the RTTY Wave/signal on my Station Monitor SM-220
with the Kenwood TS-950SDX and a Kantronics TNC
(Kam XL).

I've connected the rear cinch and the front V.INPUT
and with those connections I can monitor the band frequency and my 
output transmission (SSB/CW), but:

How I can check the RTTY output signal (wave) ?
Where to take the Mark/Space on the Kantronics or
even on the TS-950SDX ?

Many thanks for any tip.

My best 73
