[Elecraft] K2 vs. Drake 2B - New vs. classic.

[Darrell Bellerive]

I find the same thing with my K2. I originally thought that something may be 
wrong, but listening to the same CW signals on a Heathkit SW-7800 are even 
worse.

I suspect that what we are hearing is simply the solid state audio section. I 
could be wrong but I don't think that audiophiles are falling over themselves 
trying to buy audio amps with LM380 and LM386 integrated circuits.

The fact that the odd CW signal sounds perfect is confusing. I am experiencing 
the same thing.

Be interesting to pipe the audio from the detector into a HiFi tube amp.
