Could you email me what you found on the FCC site please.

As I mentioned in the other reply, HY1417LP and BH1417 are two different
devices - HY1417LP has only 16 pins but is used with a separate 6-pin chip
which appears to be the VCO.

I of course managed to leave the battery cover (with the FCC ID#) at work
last night so won't be able to look up the exact link until much later.
I've not been having any luck looking up the FCC ID#s on various other
pieces of electronics in the house. (type in the ID# exactly as it
appears on the sticker - and the FCC says it doesn't exist...) But it
worked with this device. On this URL:

you put in the ID code, look under Attachments, there may be one for a
schematic. The manufacturers can mark it as confidential but in this case
they didn't.

I was wondering if anyone found any more info on the chip (HY1417LP) I
too purchased the mp3 fm transmitter, but unlike what I have read I am
looking for which pin on the 16 pin chip is the antenna? my eyes are
not what they use to be and even using a loupe its hard to read the
curcuit board. What I would like to do is extend the antenna or maybe
built a fm booster to extend the range lets say @ 50 feet from my car
so I can listen while working outside, at the beach, etc.......
