Default Re: Hacker Sovereign II (RP25) tuning extended to 104 Mhz?

I suspect the best you'll manage is to move the whole coverage of the Hacker up by 4MHz by tweaking the LO trimmer and possibly the LO coil as well. This will lose (at least) Radio 2 and probably Radio 3 off the bottom end.


To do any better you would somehow have to increase the max min ratio of the tuning capacitor swing.
