[ARC5] BC-348Q CW Oscillator Question

[WA5CAB at cs.com]

Mark,

The table calls for rotating the Volume/Sensitivity knob fully CW.  The 
fully CW ends of the two pots are at the bottom, not the top.  With the 20K pot 
fully CW, the wiper is at the grounded end.  So the 80K resistor has no 
effect.
