Trying to build an homebrew receiver for MF band broadcast (Navtext).
Usually working on VHF, where all parts are easily found as an IC, but here I'm trying to get back to roots, so I may be missing something.
I'm considering a superhet schema and up-counting the IF to reasonable values (7 or 9 MHz). However - here's my worry. The first-stage MF mixer would have really large difference between the input and oscillator ( 0.518 MHz and 8.482 MHz) and small difference between the oscillator and IF output. Would it work anyway? Is there a better option?
