From memory, the ZN414's internal coupling-capacitors had values that meant the gain was significantly less on LW than on MW.
And the phase-modulation on Radio4 that's used for the old 'economy-7' electricity-meters for swtching between rates wouldn't be resolved by the AM detector in the 414...
TBH I can't really think of any 'professional' applications that the ZN414 would have been appropriate for.
