Testing, Testing, Is this thing On?

After reading the VERY mixed reviews on Baby Monitors, we decided that a test drive was in order before the arrival of baby.

This was our first choice because of the price and because of the lights. The lights are appealing to us because of the additional activity monitoring they provide.

I began the test some after receiving the units. I plugged in the transmitter in the soon to be baby room setting it to Channel A. I plugged in one receiver one floor up and the other receiver one floor down also all set to channel A.

The initial test was a success and the receivers were clean with minimal background noise. I decided to leave everything running during the evening and monitor it. I turned if off before bed without detecting any issues.

I powered the system back up after coming home on night #2. The upstairs receiver began howling at me right away. I turned down the volume and let it run. I came back after an hour to the same grating static.

I switched everything over to channel B. No Improvement.

I looked for noise sources in the house ( i.e. motors, florescent lights, cordless phones in use etc . . . ). Nothing seemed to change it so I have to suspect external sources of the interference.

This system is on it's way back to the store. Not sure what system is next.
