ZL3GAV-Christchurch New Zealand


Time in Christchurch:
Weather Underground PWS ICHRISTC3

I received my licence in January 2018; it took me “only” 35 years to get around to it. My early interest in radio was Medium Wave DXing using the venerable Yaesu FRG-7.

My current main interest is satellites; all modes. I am amazed as to the durability of AO-7 (launched 1974), and FO-29 (launched 1996); they are always fun to work. In ZL/VK the satellites are usually uncluttered with only a small number of active operators. {UPDATE: From mid July 2019, unfortunately FO-29 has gone silent}

I am on HF using WSJTx, mostly on FT-8, and sometimes the experimental FT-4 mode. This software offers fascinating DX propagation opportunities during the current low point of the solar cycle.

I also enjoy SSTV, RTTY on HF, and Digital Radio modes, my preference is Yaesu C4FM Fusion, and WIRESx. I use a SharkOpen Spot2 hotspot, or WIRESx on a Yaesu FTM-400XDR.

I am currently experimenting with uploading all received SSTV pictures monitored in real time to this web site; please note the information and link detailed below.

I use a Yaesu FT-991A together with an AirSpy HF+ SDR (Panadaptor), and Ham Radio Deluxe's, or SatPC32 satellite programs for Doppler control. The satellite antenna is a Arrow Alaskan crossed yagi. For VHF/UHF I use a Yaesu FTM-400XDR. Backup on VHF is a Yaesu FT-2980R which when “tweaked” will deliver 95 watts. The versatile Yaesu FT-70D is my preferred handheld.

On HF the portable Chameleon vertical MPAS antenna "system" or newly added a My Antennas EFHW are used, and a W6LVP amplified magnetic loop (brilliant) for passive monitoring. A Diamond X300NA antenna is for VHF/UHF.

I don't actively pursue QSL's, but are happy to provide. QSO's are uploaded in real time to LoTW, eQSL, QRZ.com, ClubLog and HRDLog.net or QSL cards direct (no bureau please). Return postage, IRC’s or $$ not required.

I am also on QRZCQ.com, and HAMQTH.com.

ZL3GAV QSL CARD - LAKE WANAKA SOUTH ISLAND NEW ZEALAND

I occasionally post on Twitter radio related information at https://twitter.com/ZL3GAV.

If you are in ZL, VK or Pacific Islands please email to arrange a contact on the satellites. Hawaii is potentially possible from Christchurch on AO-7, and FO-29.

Locally I monitor 146.475MHz simplex, Digital Talk-group 530 NZ National, and various WIRESx rooms.

SSTV-Pictures received uploaded live:

SSTV QSO with VK4GAP 14230Khz June 2019

The go to SSTV frequency is USB 14.230Mhz; in VK/ZL, and is usually active on a Sunday. When I am using this mode all received pictures are uploaded live. Other recognised frequencies are 28.680, 21.340Mhz USB, and 7.033, and 3.630Mhz LSB. SSTV digital modes tend to be 3Khz above these frequencies.

I also upload SSTV pictures from the ISS when available. Transmissions are on 145.800 Mhz in PD120 mode, more frequently from the Russian Cosmonauts. Occasionally there are transmissions from the NASA astronauts.

The pictures are date stamped; the slideshow view is the best viewing perspective, and sorted by “last modified” so they are shown in chronological order.

Review-Chameleon MPAS vertical portable antenna:

My review of this amazing antenna. - January 8 2019.


CLUBLOG-LOGBOOK:

The last 25 QSO’s (times are UTC) are shown here. (I do not log NZ voice contacts, except the occasional QSO where there is interesting propagation involved. I also log the first satellite QSO only.) The logs within Club Log started on 25 July 2018 when I commenced HF activity. Within the Clublog summary the “worked” are the recognised DXCC entities, and the “confirmed” are verified QSL’s via Logbook of the World (LotW). Converting worked to confirmed is always the challenge!

QSO’s are uploaded in real time to QRZ.com, HRDLog.net, eQSL, Club Log, and LoTW.


FT8 Digital Mode Club:

The FT8 Digital Mode Club https://www.ft8dmc.eu/AWARDS offers attractive certificates.

This site works on a trust basis, based on stations worked not verified QSLs.

 
 

European ROS Club:

This is another great club, founded in Spain in 2010 that issues attractive awards you can download in JPG or PDF format. Like FT8-DMC you use the UltimaeAAC software. After registering at http://www.europeanrosclub.com/en upload your ADIF format logbook.

The QSL Managers assess the authenticity of the submission, and the awards are electronically issued to download.

 
 

NASA ISS SSTV event February 2019:

During February 2019 over consecutive weekends the International Space Station (ISS) to commemorate the National Aeronautic, and Space Administration (NASA), “Nasa on the Air”, and its association with amateur radio operations from space, broadcast Slow Scan Transmission Television (SSTV) pictures.

The complete sequence is 12 photographs, and were received in Christchurch on a Yaesu FT-991A with MMSSTV software, and Ham Radio Deluxe for Doppler correction. The antenna used was a Diamond X300NA. The photos are as originally received, some are imperfect with noise caused by polarisation shifts. (The signals could vary from 40db over 9, to S1 in a matter of seconds.)

This is a video captured on an iPhone of the SSTV reception. You can see the Doppler shift with the Ham Radio Deluxe software changing the frequency. (The other software on the left on the screen is Black Cat SSTV.)
