[Elecraft] Updated and Expanded Measurements

[Jack Smith]

I've revised my K3 measurements pages today.

1. Based upon work by Larry, N8LP, I've added his suggested gain
increasing modification to the K3's IF sample output port. I've also
looked at coupling between the IF sample port and the KRX3 second
receiver and found some interesting, but probably more theoretical than
real world, spurious signals. Details at

2. I've expanded the AGC page to include the effect of varying AGC-F,
AGC-S and AGC HOLD parameters. Details at
