Listening with an AGC-free direct conversion receiver while throttling the RF
gain back would be a good starting point; they tend to add significantly less
"color" to received signals than the superhets.

Subject: RE: [TenTec] CW Key Clicks and Filters
In addition, you normally can not determine if a transmitted CW signal has
clicks by listening to it with a receiver!! If you really want to know if a
CW signal has key clicks, you must observe the transmitted waveform with an
oscilloscope or if you know how to interpret correctly, with a spectrum
analyzer or via a receivers pre-AGC IF output. Otherwise your adding a
complete receivers design components to judge...and that's not correct!
Just my opinion.
