Quake mapWe live about 20km (15 miles) due West of the Pacific coast at Napier on the central East side of New Zealand’s North Island, in a world famous wine-growing region called Hawke’s Bay - roughly where the red dot is on this handy ‘recent earthquakes’ map (which predates the Christchurch quake) ...

ZL sits astride the junction of two tectonic plates and hence has some fabulous volcanoes, active geothermal areas and, as you can see, numerous earthquakes. The city and port of Napier was devastated by a massive quake in 1931 and almost totally rebuilt in the extant art deco style, much of which has survived until today. A similarly powerful quake occurred in 2009 just off South Island, moving ZL about 30 cms closer to VK. In 2010/2011, huge quakes in Christchurch caused mayhem and destruction.

You can easily make out three major SW/NE fault lines running through North Island on the map, while South Island itself is essentially a mountain range pushed up by the colliding plates.

Our latitude 39o30’22” (=39.5061o) South by longitude 176o38’48” (=176.6466o ) East puts us in Maidenhead locator square RF80HL .

Here’s the satellite image of our place on Google Earth:

ZL2iFB from satellite

We live in the clearing that looks a bit like a giant telephone handset in the forest. The white spots in the clearing are the house and shed. The strip going SSW is a 10kV overhead power line. The other clearing SE of us is a rural landing strip used occasionally by brave/crazy crop dusters.

We are perched on a N/S ridge. It’s not very obvious from the photo but the paddock SE of the house (the phone mouthpiece) drops steeply away at about 45 degrees. It’s impossible to walk straight up or down without clinging on to a fence or a passing sheep.

Seen from space through an amazing optical system, you can see my 5 ele 15m Yagi, the workshop tin roof ground plane for my 30m antenna, and the swimming pool into which I retreat on really hot days.

Here’s our home viewed from the air to the East at about mid-day, with the sun to the North:

Here’s yet another view of our house, “Castle Peak”, photographed with a telephoto lens from a little hill way across the valley to the SE, giving a better impression of the relative height of those macrocarpa trees from which my LF loops sometimes hang ...

20 acres leaves plenty of space for antennas, though I could really have done with that passing helicopter to put some strong lines over the trees behind the property. The tower in the photo is 12m high so I estimate the trees to be about 25-30m (~100 feet) high.

Helloooo down there!

The old fixed tower was not quite as bent as it appears in this shot! I’m currently in the process of replacing it with a new tiltover tower.

This hilltop QTH has a “good views”, meaning low-angle takeoff in all directions. We can see the clear blue Pacific ocean in Hawke’s Bay about 20 km/15 miles to our East.

The great circle map centred on Castle Peak was drawn by a cool freeware program from SM3GSJ using a modified list of prefixes, trimmed down to leave just a few common and readable ones:

Our antipodes is central EA so EA appears right around the periphery of the map and it doesn’t seem to matter much which way I beam. The short path to EU flies right over JA and tends to be dominated by JAs, so LP openings to EU can be more productive for DX, although sometimes I enjoy working JA pileups as well.

The red circle on the great circle map above shows the edge of our hemisphere: everything outside the circle is on the Far Side of the Earth from us. This dramatic image from a satellite directly over my QTH shows what I mean:

Oh boy, look at all that blue ocean! There are very few hams on our side of the globe apart from ZL, VK, YB, DU, KH6, the Southern tip of CE and LU, a few frozen souls in the Antarctic research stations and JA disappearing over the edge. The Americas and Asia are 10-15,000 km away while Europe and Africa are 15-20,000 km away, out of sight on the Far Side. Few of those tiny little specks of land in the Pacific have active hams. In other words, almost all of our QSOs qualify as DX . This makes it tough going for Oceania hams to reach the top of various DX leagues, the CQ DX Marathon or the ARRL DXCC Honor Roll, but it doesn’t stop us trying!

Finally, we are usually somewhat North of the Southern auroral zone but sigs from a Southerly direction are often fluttery and weak.
