Radio Spectrum Management has granted a short-term licence, number 256129, for additional tests of Digital Amateur Television transmissions from our Mt Belmont site.

November 2016 Meeting Cancelled

WVHFG Categories

Due to the Tawa facility being used for Business Continunity purposes by the WCC, we are not able to meet there this week.

We will look at how we can reschedule the meeting and the speakers.

We do not have a December Q-Bit, so most likely we will not be in communication until Janurary 2017. Have a safe and happy Christmas.

The Last Hurrah

WVHFG Categories

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.

Digital Television tests - Bulletin No 11

WVHFG Categories

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.

AIS service restored

WVHFG Categories

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.
