We learn from the vk7wi news that Peter VK7KPC says he may have made a major breakthrough on solving the mysterious appearances of AM aircraft band signals on VK7RAA. You may recall we reported on this initially some months ago.
The breakthrough on VK7RAA was traced to one particular Bombardier Q400 aircraft, a current iteration of the now classic deHavilland Dash 8. The aircraft in question appeared to be VH QOJ, operated for QANTAS Link by Sunstate Airlines.
Peter has been able to speak to the Sunstate Airlines maintenance team and discuss this issue. By happy coincidence, the aircraft was due in for routine maintenance at the time Peter made his enquiry. As a result, particular attention was paid to the radio installation during maintenance and a faulty antenna was detected.
For good measure, the primary radio was removed, the secondary radio promoted to command status and a new secondary radio installed. The old primary rig was then despatched to the service department for a closer inspection and testing.
Needless to say, VK7RAA was and will continue to be closely monitored to see if any further errant transmissions occur. It is also understood that staff of Air Services at Launceston will also be monitoring the aircraft for any strange radio emissions.
Peter, well done on your efforts which seem to have produced the required fix.
