SYBA CM119 Modification

1

Bought this years ago to modify for allstar and now I can’t find the mod. There’s lots of others out there but it’s like drinking from a firehose trying to find it.

Anyone have this mod for this fob?

Hi, I haven’t tried this myself but it looks like the same usb soundcard that you have:

Nowadays it is difficult to get a card with the packaged CM1xx chip and not the “glued” version.

Thanks, I’m not seeing the transistor for the keying circuit or the resistors. He must have them on the radio end?

Yep, he did a separate perf board. I’m might do the same.

Yes, it sounds like a good idea. Trying to put everything in the tiny enclosure can be difficult.
