either i am not sure what to search to get info or i am finding and not sure what im looking at.
situation: i have one of the Adafruit RF key-fob and 4 - 4 channel toggle receivers.
i am trying to control 4 runs of El wire with the system. my issue is that the 3v inverter is causing interference unless the fob is right next to the receiver or disconnected.
i keep seeing sites for low/high pass filters or chokes, beads and coils. i am limited on space and the inverter needs to be rather close to the receiver, unfortunately, within 2 inches.
do i need to design pass filter for power into receiver? i know the inverter is around 2.1kHz. i need to verify actual frequency. do i need band-pass or low pass?
can i shield the inverter with some type of material like lead or something i will have in isolated area and box and only need to access to change/charge battery
can someone please point me in the right direct? TIA, James A.
