So, with a pair of basic uniden's working off the main phone jack, another phone, (bigger buttons, easier to read/dial/use) plugged into a seperate (secondary i guess, not that they arent the same lines) has persistent static/interference, and sounds awfull. I've swapped the uniden's into that phone jack, perfect, and swapped the "other" phone into the main jack, unidens perfect, other phone still awfull reception/sound. There doesnt seem to be a way to tune the frequency or anything. Anyone? It would be great to get the "phone with buttons you can actually press" working right.
