Hi;

I've recently bought two aircraft rx modules, there's only 'LOC/VOR
receiver' written on the chassis, neither manufacturer nor any additional
infos. Single aerial input, and several connectors. As I inspected, it is a
complete 108-117MHz rx, with RF amp, LO, mixers, quartz filters, and
demodulator. One of them (1990) is equipped with a PLL synthesis, and the
other (1975) has 10 switched crystals instead. Whole RX is a metal, rigid
can (as for high-end devices used in aircrafts). Unfortunately, I haven't
found any documentation concerned with it. The schematic diagram would be
the best, however I suppose this stuff is not widely available.
Nevertheless, if anyone had any info how to connect such things or make them
work, would be appreciated. Of course, I can redraw the wiring; although
that could take weeks

Cheers,
