    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I’m getting what I have always heard referred to as “intermod”, an interference from something that is locking up my Uniden 396T. I’m using it around my computer so I suspect that may be the problem. I have a wireless keyboard, a Netgear router, and a Roadrunner Motorola modem, all in the same area. The frequencies involved are all VHF-Hi (EMA, etc.) No problems on 800mhz. I’m using the standard antenna that came with the radio. Any ideas from anyone on how I can continue to use my radio where I am, near the computer.
Thanks.
Ron

Computers and their associated accessories are nasty noise generators. Scanners usually have very broad receivers. The more sensitive they are, the worse the problem becomes. I have the same issue and I imagine the only way to fix it with a portable radio is to move the radio. Basically, your computer stuff is radiating.

I've seen several reports that Linksys wireless routers put out quit a bit of interference in the 140-160 MHz area.

Re:

I strongly concur! My DSL modem puts out spurious signals all over the 150MHZ band. I have found that adjusting the position of the radio helps. Also using PL tones helps some too. An outdoor antenna with good coax like LMR-400 keeps the crud out on my amateur radios...keeps the "recieve point" away from indoor noise sources. The more wirless stuff you use the more the airwaves get polluted.
