Australian 40 and 80m QRM continues

The QRM on 80 and 40 metres, which many suspect as originating from SWHFR trials in the Torres Strait, has now been reported as having been heard in Hong Kong and Japan.

On 40, a beam heading of 230 or so from JA3 (high 3-el rotary). It is either straight south or straight north of 9M6.
Apparently on 80, this thing looks to be from northern VK4.

Another unconfirmed report plonks the interference smack on 8867, the international air route frequency for the SP6 routes.

With more on the QRM Glenn Dunstan WIA Director VK4DU.

40 and 80m wideband QRM continues

"The wideband interference signals reported last week on the national news continue to plague our 40m and 80m bands.

"There has been some speculation that these signals could be coming from a Surface Wave HF Radar surveillance system recently installed in Torres Strait." ''However, the Defence Department has advised that Surface Wave Radars do not transmit on the 40 and 80m amateur bands".

"We have received a number of Intruder watch reports on this interference, including a couple of sound bites of the signals. I have collated these reports and forwarded them on to the ACA for investigation."
