Hi all,
We have a Tx/Rx system at work that measures water level in a huge tank. The
system works but all the documentation got lost somehow. I tried to open
the Tx and Rx modules to see the parts inside but they are potted solid. I
need to document the system because the info is missing and the design
engineer left a few years back. Is there an easy way to detect the
transmitter frequency ?
We don't have any fancy spectrum analyzer but we have a scanner (scope and
the like). I tried a few of the common freqs (900, 315, 310, 433MHz, etc)
but I couldn't find it (I was told is below 900MHz). If the Tx has shifted a
bit I could be close but .... well ... the possibilities are endless so ...
I wonder if there is an easier way ?
Thanks
