[Elecraft] Listening to SSB on K2 without KSB2

[Fred Jensen]

And then there are those of us who gave much of our hearing away many
years ago and now can't tell the difference between my stock CW K2 on
SSB and a really tricked out K2 with all the bells.  In a low noise, no
QRM, strong signal environment, my K2 sounds great on SSB. In a noisy,
QRM'ed, weak signal environment, I can't understand SSB on ANY
receiver.  I think it's all in the ears of the behearer.
