Tetra frequencies for the police are from 380-385 MHz and 390-395 MHz Therefore your article is a little misleading to say the least. Also the equipment you have used for measured field strength would not give a very true reading. A receiver such an R&S EB-200 Miniport with a calibrated antenna would give you a true reading. ---------------- LessRadiation replies: Greetings to you in Gibraltar Steve. Your points are quite valid. If i'd used the equipment you suggest I'd have recorded an even stronger signal level at exactly the right frequency! Surely you're not suggesting I was picking up GSM... There are photos of the Tetra mast in question on this site. It's transmitting at 4 times the power of the GSM mast & both are the same distance from my house. A crappy £10 bug detector with LEDs on it that can only detect a proper FM bug at 2 metres can detect the Tetra mast at 500 metres. I think my DigiScout was seeing the Tetra mast, don't you? Shame you disagree - maybe you're stupid? PS I just looked up the EB-200 Miniport and it looks a bit out of my budget! I bet you don't have one in your shack do you. That DigiScout cost me £500 and has been worth every penny... I'm sure you're not stupid really, just pedantic. The screenshot of your counter is wrong.
