2012 will be the 75th Commonwealth Contest and to celebrate this we are going to have a prize draw which every entrant making more than 75 valid QSOs will be entered. And what a prize for the lucky winner - a RFSPACE SDR-IQ Software Defined Radio generously donated by Martin Lynch of ML&S.
The SDR-IQ
All stations located in one of the Commonwealth Contest Call areas (see Rules are eligible for this prize draw - making this a truly Commonwealth event.
What do you have to do to get into the prize draw? All the entrants to the 2012 Commonwealth Contest who have after adjudication 75 or more valid QSOs will automatically be entered for the draw.
The full rules for the 2012 contest are here and you are urged to read them carefully.
Make sure that you work more than 75 QSOs to leave some margin in case some of your QSOs are disallowed for some reason.
The SDR-IQ is a 14-bit software defined radio receiver. It offers a broad range of spectrum analyzer and demodulation capabilities. The hardware samples the whole 0.0001-30 MHz band using a high performance, 14 bit analog to digital converter (ADC) running at 66.6 MHz. The digital data from the ADC is processed into I and Q format using a direct digital converter (DDC). The I and Q data is then sent to the PC for processing using a USB 2.0 interface. All of the demodulation and spectral functions are done on the PC side.
The SDR-IQ comes with a High Frequency (HF) amplified front-end with switched attenuators, switched filters and 1Hz tuning. The SDR-IQ comes with the latest version of Moetronix SpectraVue and SDR-Radio software. It supports AM, WFM, USB, LSB, N-FM, DSB and CW with fully adjustable DSP Filter bandwidths and FFT sizes of 2048 to 262144 points. The resolution bandwidth is as low as 0.031 Hz.
