Greetings,

The Wellington VHF Group Inc (Branch 74 NZART) is pleased to announce the
first dedicated amateur radio APCO Project P25 repeater to operate in New
Zealand. Wellington is the country's capital city.

The machine is on 147.075 MHz (+600 kHz split) and is mixed mode. The site
is at 1,500 feet ASL.

For P25 digital access the default NAC is 293. Analog FM requires CTCSS (PL)
of 123 Hz.

Experiments in New Zealand with P25 and the previous proprietary Astro
systems date back to 1997 and 1995 respectively using a `repeater of
opportunity' that had sufficiently good frequency response to pass the C4FM
waveform.

The dedicated machine has prompted a whole new bunch of users with a variety
of surplus equipment and some keen listeners taking their first P25 steps
using various open source software packages coupled up to existing FM rigs.

73 John, ZL4JY
