[QUOTE="Vipersan, post: 978586, member: 325666"] First job .. I'll make a list of the centre frequencies of the offending data channels around 137mhz .. They I assume all have the same source.. So ...made a short list of this crap and these are not all of them .. The bursts do not neccessarily occur simulaneously ..but no give the impression of being chained somehow .. If for example 3 are within waterfall viewing range at the same time .. call them A B & C .. C can activate followed shortly after by B ...then A .. I guess this would be Trunking ? of some sort ? So here are a short list of centre fequencies .. Approx centres that is .. 137.975 137.923 137.850 137.752 137.700 137.627 137.531 and those nasty data bursts extend higher and lower than the frequency list .. So ...no escape in this region of the spectrum. I've given up hope of ever using this bit of spectrum in the future ...but still want to find out who is ruining it ? rgds VS looking at your POCSAG list of frequencies Smoggy .. we both list 137.975 ???
