[Elecraft] VP6DX -- the true story ?

[TR K2/100 S/N 838]

Dear Igor & Others,

May I speculate?

Any AGC compresses the dynamic range of incoming signals.  AGC means 
Automatic Gain Control.  If you had an invisible hand that would 
adjust the RF gain control for you, that is what AGC does.

When you are working many stations on the same frequency and they are 
very close to zero beat turning off the AGC creates a greater dynamic 
range in the ear of the receiving operator and thus gives an 
additional tool to separate the signals.

When I was a commercial operator at KPH, nearly all the operators ran 
AGC off all the time.  It makes the QRM/QRN fade away.

Eric, can you explain what did you not like about AGC in K3?
Did you notice any problems with DSP being permanently on in K3 when
listening to heavy pile ups?
