News on VK7RAA Interference from the WIA News

This is something I have heard myself, to the point that I have had to "avoid" this frequency due to to it locking up my scanner.

“We have recently been experiencing intermittent interference on the VK7RAA 2m repeater. It seems to be originating from aircraft transmissions possibly in the Devonport area or adjacent to Mt Arthur. As the originating signal is AM, when received on an FM receiver it sounds distorted.

From investigations carried out so far, it seems to be from one particular aircraft. Flights involved occur about 3 times a day to Launceston and Devonport, however, it is not always the same aircraft being used. Aircraft also may have two or three transceivers which makes the job of identifying the source even more complicated.

This interference is being investigated by several amateurs in the Launceston area.

In the meantime, please do not attempt to reply on the repeater to distorted calls which do not seem to be by amateur operators."
