Digital Television tests - Bulletin No 11

A further series of mobile field strength test runs along Stratton Street has been performed, and a report is being prepared for consideration by the interested parties.

An inspection of the BQ32 sheet of the Topo50 map series shows that some receive locations on Stratton Street are line-of-sight from Belmont and are heavily obstructed from transmitters using the adjacent 494 to 502 MHz and 510 to 518 MHz bands, potentially resulting in reception in these bands having an unfavourable signal-to-noise ratio, caused by any out-of-band radiation of the DATV transmitter.

SIG for July 2015: DMR Code plug update and overview

Since the DMR system was set up at Colonial Knob, a number of enhancements and extensions have occurred.  The code plugs determine the radio front panel channel setup, and changes have been made to make the radio easier to use when moving around the Wellington region, to support new DMR repeaters, and allow for the upcoming frequency changes.  Support for the analogue channels has been made within the local zone, and plenty of channels added to make the radios usable in a number of situations.

Accurate Transmitting Antenna Locations Using Global Positioning System (GPS) Satellites


Accurate transmitting antenna locations are required when applying for RSM Radio Licences.

The aim should be to achieve a location accuracy of 5 metres, or better. Several people have consistently achieved accuracies of 1 to 2 metres, by using the procedure described below.

Civilian GPS receivers are small and cheap, and can be found embedded in a wide range of electronic devices. Unfortunately, their apparent ease of use, and claimed accuracy, can lead the unwary user into a false sense of security, and location errors of more than 10 metres.

Do not use Google Earth. Location errors of more than 100 metres have been noted, because of the way the mosaic of satellite photos is stitched together.
