[WriteLog] W5XD keyer question

[Randy Thompson, K5ZD]

I have a W5XD MK-1100 keyer that I have been using for several years.  It is
a fantastic solution for SO2R!

Getting ready for the upcoming CQWW Phone contest and a guest op that wants
to use a footswitch (instead of VOX like I normally do).  I can't get the
PTT outputs from the W5XD keyer to key the PTT of the FT1000D!

Even when I put an ohmeter across the PTT output, it shows a lower
resistance, but not enough to get the audio tone of my multimeter to key.
So I see enough to believe that the PTT is being switched, but for some
reason it doesn't pass enough current to pull in the rig PTT or even the
multimeter audio signal.

I am connected to the tip and ring (the first two of the three stereo
connector pins).

Port set up has PTT control set to "On LPT pin 16/COMM RTS)".  Have tried
with "All mode PTT on CW port RTS" both checked and unchecked.

Anyone else seen this?  Or have an idea of what I should try?

Thanks!
