[QUOTE="smoggy07, post: 978298, member: 298987"] Has anything moved or closed local to you that would have VHF comms? It could be that something was wiping the pagers out (something close to the pager site?) so you haven't noticed them until now The main problems with pager bleed over is they're so wideband and all high powered +/- 25W so building a realistic filter is not really going to help if you're close to the site, especially if the site is using directional antenna rather than omni directional and you live in its path. If it is pagers you'll hear something like these 512 Baud [URL]http://www.kb9ukd.com/digital/pocsag5.wav[/URL] 1200 Baud [URL]http://www.kb9ukd.com/digital/pocsag12.wav[/URL] 2400 Baud [URL]http://www.kb9ukd.com/digital/pocsag24.wav[/URL] Credit for the samples goes to [URL="http://www.kb9ukd.com/digital/"]Digital Modes Samples[/URL] Install this, plumb your VAC into it and let it run on the freq that's causing problems [URL="http://www.discriminator.nl/pdw/index-en.html"]PDW Paging Decoder[/URL] It should start to decode messages for the Fire service, Ambulance service, Doctors, Solicitors and more The one thing I can suggest, and it might sound daft, is raising the height of the antenna, back in the old CB days I'd notice, when I had the antenna on a 20 foot pole, I'd crack out quite far but still get good local comms, as you would expect, but, when I picked up a cheap telescopic 40 foot mast, I'd lose local comms over DX, even when propagation was low and there was no skip about If you can do it safely and securely, before you give up hope on it, see if you can add even just 5 foot of pole to the bottom of the antenna [/QUOTE]
