Chuck - lost your e-mail address.
I screwed up on the type numbers. The ones I gave you have
photo transistor out -
Try ECG 3103  or 3101 instead.
And my aplogies to the reflector for the usage. de KL7HF

Hi Paul,

The IF-232 is strictly a level converter and an interface.  I have the
same setup as yours (TS850SAT and IF-232).  To key CW, you will have to
make up a cable from one of your serial ports or LPT port to key CW.  CT
does not support PTT, so you will have to use VOX or a foot switch, to
send CW.

You can get the suggested diagrams on the internet:

Check the ARRL Handbook for Radio Amateurs under keyers. 
In my book, the 1995 version, it was on page 22.23, figure
22.43, which described various keying schemes.

Subject: PTT vs CT etc
Message-ID: <855996351 at p180.f10.n462.z2.ftn>

Hi folks,
For some time I've been reading the "unfortunate" CT users' mail who were not
able to switch their linears to transmit while using CT and, for some
uknown reason, were needing a special "a-la" TRLog separate CW PTT keying.

We hams are known to have been smart. Let's think then.....
If there is ONE switching scheme e.g. KEY/ no matter driven by LPT or COM
port/, it can switch indefinite amount of circuits like
1.CW KEYER
2.LINEAR
3.STREET LIGHTS etc.
I recommend to read and USE !!! the following article:

"Bug Box QSK" by David P. Shafer W4AX, QST February 1980, pp.30-32.

This article gives all the necsaary information and guidelines to make the
linear switching easy. We used this approach with all our linears for a long
time with a more complicated NPN-PNP flip-flop switching of one input
relay and two output vacuum ones.
The osciliscope and some time will be required to set proper timings etc
but this is a small cost of being able to hear between dots....

Big antennas, high in the sky, are better than small ones, low.

I threw K7FD's question about getting into the speakers of an Aptiva at
an RFI engineer for Stratus Computer.  He's a friend of K1EA and a friend
of mine.  His reply:

Does it have "ce" mark on it? That means it was tested to 3 volts per
meter.

Try line filter for 3 a 120 vac on each speaker lead grounded to chassis
and
same on modem tel line also grounded to chassis. 

I know it sounds strange, but power line filters make good audio and
telcom
line filters.  Cheap and readily available at hamfests.

Also, use a line filter on the power line, grounded to chassis. This is 4
line
filters screewed to the chassis.
