Notes and Changes:
Version 3 is the version that should be ordered for any new boards. This version has a clean bill of materials, and has power protection features added to prevent failure upon loss of a single power rail.

Flipped the reference designators for ease in reading. Also added some handy test holes near the detector to rest the tip of an RF probe during RF tuning.

Values shown on schematic are for 9/45 MHz operation. Consult T1300199 for component variations at other operating frequencies.
