Once VXO coverage suits your needs you will have to secure L5 on its position on the board.
The best and cleanest option is to use a plastic retaining clamp throughout the holes on the board, as
shown in the picture.
Once the clamp is fastened you will still have some slack to move a bit the turns and make slight
adjustments. Once done, you may use nail polish to fix the turns.
If you plan to use silicone or glues, please notice that, due to their composition, they may affect largely
the characteristics of L5, even after curing. They also may absorb humidity, affecting its stability.
L6 should remain well fixed it is very important, since vibrations may change the VXO frequency
,
causing "tremors" on the received and transmitted signals.
Prior to the L5 final fix to the board make all the adjustments and checks of the rig and confirm that the
frequency coverage suits your needs.
Do not worry too much about the exact margin; is it so important to end at 40, 41 or 42 kHz?
If you are dexterous, you may draw a dial in the front panel, with a scale to help you as a guide.

T1-T2 bandpass
Note: for this adjustment you will need a trimming tool for this kind of IF cans; if you use a screwdriver you may
break and damage the coil core.
Turn P1 (RX attenuator) to minimum attenuation, that is, all the way clockwise.
