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.
