Mal,
I recently watched a TV program on the subject of 'Compulsive Obsessive
Behaviour. Although a medical layman, I was prompted to wonder whether
your obsession with CW operation described as the 'ultimate
satisfaction' did not have parallels with some of the cases shown!
I also wonder if your operating practice includes the use of a BFO or
similar as a means of rendering the received CW audible? Surely a
'purist' would prefer to 'listen' to the noise(?) changes rather than
the sounds produced as a result of a heterodyning technology? Perhaps
one might wish to consider developing a final receiver amplification
stage that could output the received signals as HV pulses to electrodes
inserted into the ears - could easily be arranged to be 'the ultimate
satisfaction'
