PDL/CDi History Version 1.0: 900 MHz RF Link
- 900MHz testing had been going on since 2009 when a prototype master modem system was installed at Port Alma plant, on the old "TV" tower about 60ft above ground level. There was this YAGI on the tower, remote testing consisted of running around the lake on the KJ and making signal strength measurements. The prototypes were used as vehicles to develop code, a successful strategy. See first row of pictures below.
- A second master system was installed at Morpeth plant tower in September 2010. This system was never used, see second row of pictures below.
- In December 2011, the old "TV" tower was replaced at Port Alma and a new, directional master system was installed, see third row of pictures below. This system was used in May 2012 to remotely download a datalogger at 353S, some 38 Kms away, establishing the first and last distance record. The picture on the left shows the remote modem connected to the datalogger below. See third row of pictures below.
- The Port Alma master system was eventually moved to a plunger lift candidate well in Rochester, Ontario. The objective there was to publish remote data on the internet and to also control the system and download remotely through the internet.
- The test system achieved its objective of publishing data to the internet using a device known as the "Flyport", the recorded data is still in the cloud. In the meantime, the Flyport was being replaced by the FlyportPRO by the manufacturer so a test system was built to replace the original Flyport.
- Unfortunately the test remote system disappeared from Rochester, never to be seen again, "safety" excuse invalid for years.
- A system similar to the original Flyport has been running for several years now, hardware investment $75, more info here.
