Water plant telemetry
From Signal Identification Wiki
Water stuff telemetry signal[edit]
It is received all over Hungary, on many frequencies in the given range. Some of them are simplex, some half-duplex. It's telemetry from water plants/pumps/etc. They are working with 10 or 10+ element yagi antennas. I would like to get some help on decoding this signals. What are your ideas for the modulation? Thanks.
