The VT pin on the decoder side (signifying a valid transmission) flashes intermittently (sort of imitating a square wave pulse)
This happens without me making any change in the circuit - no address change, or TE' (transmission enable, which I have permanently grounded).
I put together a circuit that follows the schematic:
on the encoder side and
on the decoder side.
I'm using a Hi-Waote 6f22M battery power source, in case it is important.
Any reason you guys could suggest as to why it's not permanently high on the VT pin?
