Rebuilding telemetry set to 2 meterband packet node controller.
At a bunker meeting, someone had brought with a nice piece of radio technique: A transmitter used by "Rijkswaterstaat" to pass on data about water levels to a central point:
The transceiver and receiver can work on several canals crystal-controlled.
The frequency is just above the 2 meters amateur band (In this manner around 150 Mhz).
The transmitter has a power of 1.50 Watt and works in narrow F.M. mode.
The Veron Vlissingen Crew has converted the set to A.P.R.S. land-mark on the 2 meters band.
Unfortunately, we have we of these sets no diagrams or further documentation.
