Hi Nate,

Thanks for the welcome! The "extra sauce" that cwdaemon provided was a way to extract the messages being sent by tlf. To be clear, when you configure a key in tlf to send out their callsign and your RST, the string that gets sent to cwdaemon is the exact text entered by the operator, so you get a callsign and the exchange as sent (as-if it was going to be turned into Morse code).

I extract that message and use it to generate appropriate voice signals.

Keying of the radio for me is currently achieved by VOX, triggered by the audio sent to the radio.

I have no issue with using hamlib, but I didn't explore to see if there was actual message text being sent to hamlib that is intended to be Morse.

As for the unhealthy obsession, I've been at this since the 6502 :-) Amateur Radio was supposed to be a way to do technical stuff away from computing. Little did I know a decade ago that the two are on an increasingly narrowing road on the way to the horizon!

In my RSS feed comes this from Onno, VK6FLAB, writing about his SSB
keying shim for SSB through cwdaemon:

Good article, Onno.  Just one question, are you aware that Hamlib
supports PTT keying via radio command when the radio supports it?  I use
it with my K3 and voice messages.  Of course, not all radios support it
so something else is required.  Hamlib also supports keying the radio
via an RS-232 port and such, so I'm not sure where Hamlib fell short for

Regardless, welcome to the unhealthy obsession with software
