Bitx3B VFO stage picture has been posted here. The Bitx3B VFO is made with two number's of
T37-6 stacked together and quick fix applied on it.
The trimmer at control of FLL will need to be engaged at such a point as to observe the least drift .
The VFO is rock solid and i did not find any drift .
The FLL menu switch has been soldered on the solder side of PCB, so that it could be easier pressing the switch while adjusting the BFO or VFO to set their frequencies.
