Just to confirm, is it the band that ranges from 160-164 MHz???

If so, it's the frequencies used by Canada for continuous (marine and public) weather broadcast. Should be the same for US. Don't know for the rest of the world...



And I just can't seem to find any datasheet concenrning receiver model 1385 on microtune webapge. 1383 and 1384 are there though. Was the 1385 a custom made tuner?

Here's the Microtune Automotive Products page on their website.
