In the 1956 novel The Last Hurrah by Edwin O'Connor the veteran, a flawed but great man with many achievements to his credit, falls to the modern usurper with a handsome face but no real ability. And so on February 16, 2016 an iconic veteran of New Zealand radio transmission, the 696 ft* 2YA mast fell to the enfeebled broadcast service we make do with today. Welcome to the new age.
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.
Today the Rangituhi - Colonial Knob AIS service was restored to service after a failure of the VHF receiver. Coverage from the site has been gradually deteriorating over the last few months.
Last weekend a working bee installed a new VHF marine band antenna at the site. The new antenna is a PD220 Celwave Super Stationmaster with a gain of 5.25 dBd (7.4 dBi) arranged with a 6 degree electrical downtilt.
For more than 25 years, first analog then P25, the 147.075 MHz (+600 kHz split) repeater has covered the north of Wellington, New Zealand. The original machine was a home made crystal controlled 10W design by Peter ZL2ARW but the site now features a 100W capable Motorola Quantar.
The marine AIS (Automatic Identification System) is an automatic tracking technology used by ships to send and receive position reports. Vessels send positions derived by GPS to inform others and optionally receive positions from other vessels for local display.
