The IC-706 works like a charm with the SCS PTC2e. One quirk -
I installed a 500Hz (FL-100) filter and told the IC-706 that
it was an FL-223 (SSB) filter so it would switch the narrow
filter in for PACTOR operation using SSB mode AFSK. I got
my IC-706MKII from AES as a closeout at $998.

Subject: Audio distortion with PTCII and Kenwood TS450
For the past year I have been using a SCS PTC-II to do Pactor II email
from my sailboat while cruising the Pacific Coast of Mexico. The
PTC-II is connected to my Kenwood TS-450 via the auxillary port in
the rear of the radio. It works great except for the fact that the
radio totally distorts the broadcast audio when the cable from the
PTC-II is plugged into the auxillary port. Since I use the radio on
a daily basis for both digital and audio communications it is a bit
of pain to keep removing and replugging the plug on a 2 to 3 times
per day basis. The way the radio is installed on the boat the back
of the radio is not very accesabile either but I manange.
SCS is aware of the problem with the Kenwood TS-450 but has no
knowledge of a fix. Does anyone know of one ?
I may decide to replace the radio with a newer model, does anybody
use a Kenwood TS-570D with a PTC-II or PTC-IIe ? Does it exhibit the
same problem ?
How about one of the newer Icoms or Yaesus ?
Thanks for any help.

Sounds like RF getting in on the cable.. how about trying one of the
larger snap-on ferrite RF protectors that latch around the cable ??
See if the problem goes away when using one ..

Isn't the problem that the microphone audio input and the auxilliary
audio input pins are simply wired together?

Yes. The archive
ftp://ftp.ucsd.edu/hamradio/packet/tcpip/nosview/nosvw304.zip
contains a version of KA9Q NOS for DOS along with a packet driver for BayCom,
which I have used since 1994.
The Tigertronics website has
http://www.tigertronics.com/files/jnos_bay.zip
but I haven't tried it.
