I recently built an AA-908 Antenna Analyst which is a SMD-based kit. I have

including a K2 (#1107) with 100 watt amp. DSP, KSB, NB, 160 meter and various

I was aligning my receiver yesterday (Phase II).
I noticed that the AF gain seems to be exponential,
which is to say that rotating it from 200 degrees

produces only a little bit of volume increase.

My question therefore is... how much should you turn

360 degrees more than once? Can
