Picture shows modifications made to the VFO for SWL reception.
First, the 10pf coupling cap is changed to a 47pf NPO.
Second, the 68pf NPO capacitor and the Photodiode are not installed.
Third, a wire is soldered to the "A" terminal of the Photodiode and wired to an SPST switch. The wire is not shown.
All the stabilzer parts are installed in this picture.
The 39pf cap has short leads and needs to be bent over to allow enough lead length to reach the tab on the main tuning capacitor.
Bend lead length on bottom side of hole against the PCB to keep out of way while working on the rest of the parts.
