For example, if you want to listen to CW mode on 21 MHz you should adjust the frequency range of 6.000 - 6.060 MHz.
.. But if you want to listen to SSB you should adjust the frequency range of 6.190 - 6.250 MHz or more.
18 pF capacitor in VFO circuit you can change to more value if need wider bandwidth.
If possible, you must use 10 turns Pot is very easily to frequency adjustment.
