Don, It's a coincidence that I am adding a WX-1000 weather receiver/alarm system to one of my 2m repeaters, and I found that the 2m signal was clobbering the WX unit. Even moving the WX receive antenna away from and behind (it's directional) the 2m antenna didn't help. The solution was to connect a small Sinclair preselector in front of the WX receiver. These little gems are about five inches square, and have four helical resonators. I tuned it to the WX frequency, and eliminated the 2m interference. Preselectors are not cheap, but DCI will make you a nifty filter, similar to the ones for 2m, that passes just the NWS frequencies. It'll cost about $100, since it's a custom model.
