Re: [HCDX] Good News from Tazzy Tiger OHR in Tasmania
IARU-MS was only concerned with keeping TIGER out of the 10100-10150 kHz 30m hamband, but where else might it be? pdf link below includes this:
On a real time data display on internet you are able to read the transmission frequency of the different TIGER radars. You can also see a picture with the "fan" in different colours showing the structures of the ionosphere. Please hit http://www.tiger.latrobe.edu.au/
And the above link includes this, rather unspecific info:
``TIGER is controlled remotely from La Trobe University in Melbourne, Australia. It uses HF radio waves in the 8 - 20 MHz range. It consumes only 2 kW of power, the same as some electric kettles and transmits an average of 200W - the same as two bright light globes.
``TIGER typically operates near 14 MHz during day-time and 12 MHz at night but this changes with the level of solar activity. It is also capable of swept-frequency operation meaning that when irregularities are widespread throughout the ionosphere, the radar detects ionospheric and sea scatter over much of its range window and over a broad band of frequencies``
Altho obviously doing valuable ionospheric research, which might even be applicable to SWL/DXing, it seems it could also interfere with many other transmissions unless it is disallowed e.g. from broadcast bands. I have enquired about its actual frequency usage (Glenn Hauser, DX LISTENING DIGEST)
