The North – South 2007 DXpeditions

Over the Easter Holiday Weekend in early April, DXers congregated in Southland and Northland to try for exotic DX from electrically quiet coastal locations. The keen DXers at Tiwai near Bluff at the very bottom of the South Island were Ray Crawford (Queensland) with a Drake SPR4, Steven Greenyer (Timaru) with Palstar R30, Arthur de Maine and David Headland (North Otago) listening on an AOR7030+ and SPR4 respectively and Paul Aronsen (Invercargill) with a Kenwood 5000. Antennas included various Beverages, long
wires and a EWE. In the far north, at Mangawhai, Bryan Clark and David Norrie were both using AOR7030+ receivers.

Reporting on behalf of the Tiwai DXers, Steven Greenyer writes: Paul and Arthur arrived early on Thursday and had the coal range going and the kettle on the boil when Ray and Steven arrived. Paul had erected a couple of temporary
antennas to which were added Steven’s portable EWE aimed at South America. Ray and Paul had a test of Paul’s Ham transmitter. The portable generator was cranked up and the house batteries given a top up until listening started about 0400. Only a few weak signals and hets were audible at this hour. By 0500 most frequencies had Latin signals with a few X band Yanks coming through; highlight being WMLB on1690. Around this time a few Mexicans also appeared. By 0800 several of the 50kw Yank channels had reasonable signals although noise levels were rising.

Friday saw the arrival of David Headland. A reasonable number of South Americans were in by 0430. Following a break for tea a return to the dials around 0700 showed a number of signals from Chile and Argentina unfortunately by 0730 the signals were beginning to flutter and dropped out shortly later, we should have eaten faster as we may have missed the best. A text from Bryan Clark indicated Spanish on 530, was he looking for Falkland Islands? Unfortunately Alexandra on 531 ruled this one out from Tiwai. Apart from a few X band stations and a couple of the stronger South Americans like Peru 1470, the b.c band was quiet for the rest of the evening.

Saturday afternoon saw the arrival of Southland branch members, Arthur Williams and Don Collie. A trek led by Steven over the paddocks and along the beach filled the early part of the afternoon. DX started again about 0400 and was dominated by Colombians with the highlight being the return of the 1510 Ecuadorian time signal station. Apart from a few regulars, signals faded out around 0800.

Bryan Clark and David Norrie phoned in from Mangawhai with a report of what they had been hearing – this illustrated the difference in conditions between the two locations and what was being heard. This was also the night the rats started playing in the roof.

Sunday saw the group meet up with some Southland Branch members for a visit to the Communications Museum at the old Awarua Radio site. We were welcomed by Brendon Sparks and Paul MacKay who presented a slide show on the history of ZLB Awarua Radio followed by a further show on the Invercargill telephone exchange, then a look at the various historical radio and communication exhibits.

Next stop was Eric McIntosh’s for a fish and chip lunch, it was supposed to include oysters but Paul had trouble finding a fish and chip shop open, let alone oysters. After an enjoyable lunch with Gwen, Raewyn, Phyllis and Bernice, the DXers headed out to Southland Branch member Colin McLean’s home to view the impressive collection of radio and electronic equipment he has collected.

Broadcast DX was a bit more promising this evening with several interesting signals from Argentina and a few new stations. Unfortunately it faded again by around 0800. Monday the Latins were in earlier with many interesting signals especially around 1300-1400 kHz, unfortunately they experienced a lot of fading and with the exception of a small input from the USA signals dropped out by 0800.Tuesday saw us packing up and heading home. Overall conditions were not as good as last year with earlier fadeouts and generally weaker signals, but we all had a good time and talked about whether this would really be the last Tiwai Easter get together.

Bryan Clark writes that it was most interesting to be able to compare medium wave receptions from the 2 locations in the same time periods, using mobile phones and text messaging. In the south, reception appeared to be more focussed on certain regions of South America such as Peru and Argentina, whereas in the north, stations were audible from as far north as Chicago, right down to Chile. However this probably reflects the differing antenna configurations at the 2 sites – Tiwai has longer Beverage antennas (up to 370 metres), which are far more directional than the short 100 metre BOG (Beverage on Ground) antennas used in Mangawhai. My listening highlights were both low frequencies – Morocco on 171 longwave and Voz Cristiana in the Caribbean on 530kHz. Both were unexpected, the first because longwave is generally very noisy, the second because of a semi-local station just 1kHz away! Reports have been written to both – my first sent out in over a year! Says David Norrie: Thanks to Bryan for the invite up, good conditions and some nice catches but the usual frustrating fade outs.. All part of the fun!
