I had a modified PK-232MBX and used it with a 400 HZ CW filter in the
TS-850S/AT. It worked very well but you needed strong audio to make it work.
I
made 1000's of RTTY qso's with it. For a while, I had a Dovetron MPC-1000C
terminal unit as a front end for the PK-232. It worked very well.
I then started using MMTTY when Writelog got a MMTTY plugin. I ran them both
for several week and in a rtty contest or two.
MMTTY blew the socks off the PK-232. I packed up the PK-232 and it has been in
the box ever since.
I think the soundcard rtty is by far the best until something else comes along.

REPLY:
I have a second computer with an audio spectrum display which also automatically
displays the shift numerically, and I have observed that somewhere around five
percent of stations are using 200 Hz shift. That figure of five percent is just
an estimate - it could be a bit more or a bit less, but it is definitely not
zero. FWIW.
I have not compared MMTTY against the PK-232, but I have run it side by side
against a KAM and MMTTY wins hands down when signals are weak and/or covered by
QRM and QRN. I suspect the same would be true of the PK-232. If anyone has
actually run them side by side, I'd be interested to hear the results.
