I have puchaed a wireless Bike Alarm and wanted to figure out how to extend its range. I want to try to extend its reach to 50 meters from the default 20 meters.
There is wireless "fob" (KS-WL09C) that I disassembled. The photo is available below. Question: Can someone, please, spot a transmitter on the photo? If I know where it is, perhaps, I can add an antenna to extend its range.
I was trying to search the schematics online, but could not find anything. I was also trying to google the names of the element IDs that are imprinted on them, but didn't find anything either. The device also has something written in Chenese that might be useful, but I can't read it.
Context: I am a beginner, but know some basics and I know how to solder.
There are 4 buttons:
- On button
- Off button
- PA button
- CH button
