[Dx4win] Still fighting the LPT keyer - DX4win thing

[on4vp]

Hi all,

I have an update on things.
Replacing the optocoupler with a 2N2222A type transistor (needs less =
current to give 100% saturation) helped me getting the LTP circuit to =
work.

I now can key both the IC706 and TS570DG with the homebrewed circuit.  I =
now use exact the same circuit as described in the DX4WIN helpfile.

BUT !

I only can key both transceivers when using UA9UOV's CWTYPE and NOT when =
using the build in keyer of DX4WIN.

When using the keyer inside DX4WIn (Alt-K) when I start a message, I get =
a contignous tone untill I shut down the keyer function in DX4win or =
start up CWTYPE.

Strange things happening here.

Any ideas ?
