As for the wireless, I've also got a Linksys WAP01 access point within 5 feet of said PSR500, again w/o any real problems. I've also got it connected to an external anntenna, which (I find) really improves the reception. Granted there is a bit of overload in the frontend, but I can live with it. As for the network cables, I'm simply using regular unshielded twisted pair cables, (granted, the longest one I'm using is about 15 feet total). I'd also like to hear others views/opinions on this issue.

Although the networking equipment itself (internals) may cause problems, it generally is more likely that the ethernet causes the problem. Could be that the ethernet cabling is acting like a nice antenna to radiate any of the emissions that are usually kept relatively quite inside the device - or it could be that specifically the ethernet transceivers are noisy.
But I've had this problem with an old D-Link hub (which I specifically used at one point to force 10 mbit on links for which the devices themselves could not be forced 10 mbit - such as speedstream modem, linksys router, etc.). Sure, I could have wired up a cable that specifically only supported 10 mbit FD to force it, but it was easier to put the hub in place. The problem was less into the hub, but not because of anything other than the fact that all the equipment was forced to 10 mbit, which will inherently lessen the problem.
If you're using an external antenna and it's a fair distance from the networking devices and coupled to your receiver with good coax with decent shielding, then you may not suffer so bad simploy because of that.
When I have the handheld on INSIDE the house about 20 feet away in the basement, I hear way less noise using the ducky than I do using my DPD OmniX (mounted outside about 20 feet up and 20 feet away, with the coax (LMR400) running right back in to the house about 10 feet from the networking equipment.
I'm sure some people don't experience these problems, even with the same devices, depending upon how they have everything else set up. In my particular circumstance, my receiving configuration is working against me when it comes to trying to eliminate the noise from the networking devices. I'm pretty confident that the devices in general are still emitting the noises even if you don't hear them with your particular receiving configuration. Linksys routers are really famous for this. The 2wire causes problems to a lesser [but still noteworthy] extent.
I've had a lot of recommendations for resolving this [most of which I have not tried, but many of which I'm sure would at least help the problem]. I'm just too pissed off about it in the first place. My solution was to go completely wireless, with 54 mbit across the board on all the computers in the house. When I want to listen down low, I unplug the IP phone (connected via ethernet).
