Customer Question I have a Radio Shack FM Wireless Intercom System (#43-3105). Not sure if it is wireless or not, actually. I often get static/noise on a unit in the system for no reason that I can determine. Have not been able to find a line filter for sale anywhere. Manuals and free owners instruction pdf guides. Find the user manual and the help you need for the products you own at ManualsOnline.

Radio Shack no. 43-3105 wireless intercom works well if all units are connected to outlets that are on the same AC electrical phase. In some homes individuals report that they are clear and work well. In other homes owners report static and interference.

The manufacturer warns that the intercom system might cause TV or radio interference even when it operating properly. This is because the units work by intentionally putting noise in your home electrical system. At the frequency these operate, the noise generally goes unnoticed, however, it is still signal in the electrical system other than the 60Hz AC.

The model uses three AC-Cap Suppresion,0.022uF 275V X2 Polypropylene Film Capacitors which are interference suppressors for across the line applications. The 'bridge' between the AC current and the onboard circuitry begins with these three capacitors. The board itself operates on 10.6V DC. The RF modulation is injected in the power cord from two poles into Black and Green on one and white (common) on the other. The hot and ground are bridged opposite two separate capacitors (2 of the 3 Suppression AC-Caps.)
