1) If sensitivity of frequency counter is too low adjust to max. channel separation
(input signal: stereo left 90% + 9%, adjust output on right channel to minimum)
2) RC network serves for damping the IF-filter while
adjusting the other one.
3) For AM RF adjustments the original frame antenna has to be used!
