If they ever get around to using it, there is also a nice birdie on 145.870! My solution is to use ferrites on both the power and Ethernet cables from the router, and also use the mast mounted preamp. That is far enough away that the downlink swamps the birdie. Since most of the noise goes away when you unplug the Ethernet cable to the desktop, I have been considering switching that to RF as well, as I have an unused PCI card handy.
Another option beyond the ferrites may be to try a different power supply or AC adapter. Most of these routers are now using a small switching power supply, which are lighter and smaller than a traditional transformer-based wall-wart adapter would be for the same voltage/current requirement.
73!
