About the Alex Module

Alexiares (or Alex for short) is a set of RF Bandpass filters for use with Mercury or any other SDR.

The Penelope and PennyLane boards comply with FCC regulations at 1/2 W. If you amplify your signal you will need some filtering. This board set provides a high quality filter set.

The project leader for the board is Graham KE9H.
