[ARC5] Visual alignment BC-454 - bit more

[Kenneth G. Gordon]

Sweeping from 1402.27 KHz to 1417.87 KHz, or 15.6 KHz., center frequency appears to be 
1410.07 KHz.

Increasing the signal generator output from 100 millivolts to 300 millivolts broadens out the 
bottom of the trace, but doesn't affect the peak.

I can feed it so much signal that the trace widens out drastically and the relative height 
reduces to very flat.
