XTAL choice for 455-12 DRM converter

14060 kHz / 32 sounded good.

So does 7030 / 16.

How about 7040 / 16 then?! It gives 440 kHz, that is even closer to the I.F. of 455 kHz.

I should add this feature to my xtalfind.pl utility.

I also tried out the receiver and with my finger as antenna a DRM transmission was clearly audible on 9.8 MHz band. So I'll proceed with this IF downconverter project.
