  1. I also had a 40channel mid band rig, AM. It was hooked up to a DV27 in the loft on a biscuit tin with loads of tin foil. I also hid mine behind the tank in the airing cupboard!!! The threat of detection was real enough, especially when a neighbour reported you. I had one visit later when I had a 40ch FM radio. The man in the van went next door and listened to me on every channel using his modified Pye Pocketphone or something very similar. He looked at the licence, come back and said that it was the neighbour's TV. Years later I got a Multimode 2 and then a UNIDEN 2830 I had many contacts on for years. I also had some wild aerials from dipoles to silver rods. Unfortunarly a 5/8 wabe on a 30ft pole blew down. I started using a linear amp at one point and was obliterating TVs and radios a few roads away. I was using a temporary aerial in the garden and one night heard a commotion. A radio amateur two houses away was having his door kicked in by RIS and police. They had tracked it to the wrong house. A few years after moving from there I took my Class B and then my Class A licences, but found amateurs really boring old people. I preferred CB for the people I spoke to, amateurs just wanted to bore everyone about what they had, radio and electronics etc, not everyone wants to talk about all that every day. I prefer data modes now.

  2. Not always accurate or covering every detail. The remote monitoring stations used SDRs from around 1992, they were located at every BT phone exchange building and monitored the spectrum in each area. Pirates were identified quickly as there was a setting to only show new stations that were not known. They were also combined to give direction finding. This same system is still is in use today and is VERY accurate now, accurately locating people within a few metres. I have seen it in action for locating people jamming emergency services. Once a report was made, the source was identified and located within 30mins. It used to concentrate on anything 4M and above, not it does HF and in to the microwaves. The equipment is also used by GCHQ to monitor WiFi and was tested in a program of WiFi interception by monitoring home WiFi in a particular area and using packet injection etc. WiFi has a number of vulnerabilities so it is possible to force disconnects to get a password for example. Security Services were using this and still do. The official line in the Press when someone found out was that they were looking who had not secured their WiFi to try and help them improve security. Your local BT exchange has a lot of extra equipment installed used by many agencies...look at the aerials on the roof that are not for mobiles or TETRA.
