Some years ago, a few of us would occasionally have QSOs that we called
"Martin Luthers" -as in "I had a DREAM last night!" and we'd send off the QSLs
and would often get one back! This was especially true on 160. I still,
occasionally , have a "Martin Luther"! Straining right down into the noise
level and QSB for ESP-level signals!

positively contribute to listening fatigue and others negatively... Quality
of DSP and operators ability to adjust are key factors here. This is a
topic I follow closely, but can't think of any articles or studies off hand
that would answer your question... A sold PhD thesis topic this would be.
