[Elecraft] K3 - WinkeyUSB Keying Issue

[Poul Erik Karlshøj (PKA)]

Jed, I would also suspect the cable (having had some problems with one myself).

Not directly related: I have just tried connecting two winkeyers in Server/Client mode. It works great. I just came back from a short trip to OX and worked RC on internet with a 200 msec delay and it worked real nice. Used a WK-compatible keyer from G3ZLP at the Client end and an original Winkeyer in the shack at home. It is certainly an easy way to operate remotely using a paddle.

The optoisolator (U1 or U3) that 'closes' the key contact may have enough resistance to keep the K3 from keying reliably.  It would be informative to hang a DC coupled 'scope probe across that WK output to see if the voltage is really going to zero during keydown periods.
