Re: Hacker Sovereign II (RP25) tuning extended to 104 Mhz?
These pictures show the FM tuning capacitor - it's not a type that lends itself to this idea, as the plates are very small, and relatively thick. Also, when fully open, there is no overlap at all, so I fail to see how bending the plates will reduce the minimum value of capacitance. In short, just don't.
Whereas adjusting the oscillator trimmer is very simple and completely reversible.
Having adjusted the oscillator trimmer (and core if needed) to get the coverage you want, it'll be worth adjusting the RF coils for maximum sensitivity - it makes quite a difference. Repeat the adjustment several times, as they interact.
