My main XCVR is a Hermes Lite 2 running with various softwares, mainly SparkSDR and Thetis but also Quisk.

How can I work CW with Thetis, where can I plug my paddle or can I manipulate directly with the keyboard as I can do with SparkSDR? Is there a CW decoder included in Thetis?

The HL2 has no internal keyer so you can plug either a straight key or the output of an iambic keyer into the front KEY/PTT jack. It's a stereo plug, the tip being the keying input and the ring being PTT. Many folks build or buy a simple splitter cable to accommodate both functions at once. No sidetone is provided, I just use the one built into my external keyer.

The CWX menu at the top of Thetis will open up a CW utility with a keyboard and memories.
