I have sent off for a radio wave detector, whatever this is, it is also screwing with my TV as well. I presume someone with a CB or illegal device is nearby. I have complained to the radio interference government agency, I had this years ago. Pirate radio. well not the sort of pirate radio I knew. Glad when they raided them. Music was ****e, found them on the FM band. I think this is 4g playing a part. You may get a call from BT for a upgrade to your hub, these work on multi frequencies and 4G phones piggy back on your WiFi hub. This is a open system, not the same as before, no password is required. It's well written up on line. Harmonics in the radio spectrum are picked up by the early P38 receiver. Wammers, I had not messed with the Nanocom on the P38, all this just happened, only time will tell. I hope things stay the same. I only plugged in the Nanocom after the engine stopped working. it was a total mystery. The fault codes stored were the only thing read. The nanocom guys suggested a update and this was done. No outstanding data or settings was detected. All settings were as before the engine stopped. But the bluetooth diesel emissions detector at the mot was used and after that the troubles started. In Birmingham the RAC plugged in their laptop and they got it going after I parked next to a WiFi repeater. For anyone in Brum the Ibis at Holloway circus is a motel/chalet type place and they have so many wifi repeaters, one for each room. The RAC guy had a detector and it was off the scale. Away from the hotel we got it all running, the RAC also use bluetooth. I hope to get some readings.
