[Elecraft] Cw decode text, again

[GDR]

I know how to get the K3 and the KX3 to decode and display text, both sending and receiving, using the internal keyer and off-the-air signals. What I need is for either radio to do it NOT using the internal keyer. I also know I could send radio-to-radio but I would rather not do that. Can anyone suggest an alternative method? Or, where can I get a third party code reader that I can connect a bug straight into?
