Hi I now think in this day and age scanners are a thing of the past!!!.
Most companies provide digital radio's to there suppliers and the standard scanners do not pick them up even the new 446 Mhz band has now gone digital I have had a scanner for years and more companies are either going to digital or mobile phone systems so Why buy a scanner ????. .
Ok if you like to monitor aircraft the odd minicab that's fine but most shopwatch and the more interesting frequencies have now gone.... This is just my thoughts on the subject and I hope it does not put anyone from becoming a SWL.
