SONY AM/FM RF Block Module - spare part

Ex Sony product, working prior to removal.

This is your pretty traditional RF module which provides 2x inputs (coax and balanced antenna) for the reception of AM & FM radio broadcasts

Only marked externally as SEK 02

Fully enclosed tin enclosure, the top is removeable

Inside, the brains is the Sanyo LA1837 integrated circuit which is designed to provide in a single-chip, AM/FM IF and MPX functions along with electronic tuning using SD and IF counting systems.

External connection to the rest of the equipment is via a flat ribbon cable

Unfortunately, I have no information on the pin designations/purpose though (13x)

PCB Part number is 1-681-692-12

Module measurements: 73mm x 50mm x 21mm

Mounting is via two threaded holes at the connector end of the enclosure
