Here I have a small transmitter to remotely operate a water pump, it is kind of a "generic" remote cos it has 4 buttons and only 2 are needed, I have also seen a seller in china selling these on ebay listing with multi use.
Anyway I have 2 water pumps, and 2 remotes, which work each others receiver, and this is a problem, so I wanted to change the component pointed by the arrow, after my research i determine it could be a ceramic resonator (I assumed it was a crystal oscillator but I dont see 2 capacitors, this thing has 3 pins so I believe it is a ceramic resonator instead)
So I basically just want to buy a resonator of different frequency so both remotes operate different pumps (I realize the receiver will need resinator/oscillator changing also)
On the 2nd picture the circled area are the resonator pins, 1 of them is grounded, and the voltage across the ground pin and other 2 pins matches that coming off the battery (supposed to be 12v but it has been used a while and has dropped to 10.73v, well 1 pin is this reading and the other is slightly less)
When looking on ebay i see ceramic resonators which look very different in physical appearance (brown/orange or blue blobs with 3 pins in line coming out the bottom), so would 1 of these work?
The writing on the component is hard to read (partially rubbed off), it looks like it reads BX R433A (last 2 characters very obscure so may be wrong).
Any advice much appreciated.
Thanks in advance
