A superregenerative type radio receiver is provided that is particularly adapted for avoiding frequency shift of the receiver from a preselected tuned frequency regardless of installation environment for the receiver. The receiver comprises a superregenerative radio circuit and an associated antenna mounted on a circuit board and received in a container including a wall portion reflective to radio transmissions. The radio circuit is disposed to the wall portion to shroud the radio circuit whereby the radio receiver is adapted to be installed near metallic items and maintain tuned frequency stability.
