None of the Icom transceivers work with AFSK in RTTY mode. To
operate AFSK you must be in LSB (or USB) for any rig prior to
the IC-746Pro or IC-756ProII.
Icom introduced LSB-D/USB-D in the 746Pro/756ProII which, I
believe, mutes the microphone (uses the ACC jack for audio)
However, LSB-D/USB-D still uses the wide USB/LSB filters
rather than the special RTTY filters.

PS. If you want to avoid the "hot mic" and "windows noises"
issues as well as have an interface that supports all
modern computer controlled radios, your choice of Windows,
OS-X or LINUX, and FSK (EXTFSK in MMTTY or "Software FSK"
in RTTYRITE, pFSK with fldig), look at the microHAM USB
Interface III: http://www.microham-usa.com/Products/USB3.html.
The USB Interface III includes the transceiver interface
cable and costs less than the RigBlaster Plug & Play when
you add up all of the required cables/adapters and a
separate USB soundcard.
