My first 900 MHz was a (state-of-the-art at that time) 2-line 
spread-spectrum unit that worked almost a mile away from home, even with the 
base inside my house with grounded steel siding. I had the 2nd phone line 
connected to my computer sound card, for experimental VOIP use. It even 
supported hot-swapping the battery with a second battery that charged in the 
base unit, without losing the signal. Unfortunately that great phone died 
long ago. My one-year-old cheap analog 900 MHz barely used to work outside 
near a window or door, but now barely works a few feet from the base unit, 
probably from neighborhood 900 MHz interference. I just want to know what 
phone to get that won't interfere with my D-Link 2.4 GHz WAP or my Netgear 5 
GHz WAP. Even a 900 MHz that works with no chirps/clicks/pops in my 
neighborhood would be fine...
