[Elecraft] K2X HRD PTT interface

[Jim Sr Sturges]

First post. Connecting KX2 to HRD on Surface Pro 3 using provided ACC-USB
cable, and audio via cables to a USB sound dongle.

PSK-31 using USB mode on 20M: Receive works great. When I transmit, TX
light comes on, data is sent, but TX light stays on even though transmit
power drops to zero.

Would like to have transmitter stop!

Anybody have the majick mouth-holding tricks?

Thanks in advance and 73,
