If you hear this on 2 metres, blame the USB hubA new kind of interference may be coming to the two meter band near you. It's already bothering hams down-under. Graham Kemp, VK4BB, has more: Recent investigations by the Australian Communications and Media Authority (ACMA) in Queensland, over the last fortnight, has detected a non-approved computer device that emits a signal on 144.600 MHz. The device is a cheap, Chinese made, Active USB Hub. A sound file of the interference is available at: http://reast.asn.au/soundfiles/2Mnoise.wav If anyone is experiencing the same type of noise, it is most likely one of these devices and is probably located within a few house blocks of the receiving station.
Graham Kemp, VK4BB • It's unknown if any of these interference-emitting hubs have reached US shores or if they ever will. Should they, you will likely find out about it when your turn on your 2 meter base or HT.
