The question is whether or not Recovery RX-Extra (or whatever the higher power device is called) use a different frequency than the previous devices. To date everything BIEL has made and is cleared to market uses the same frequency. Are you claiming the new device will operate a a different frequency? The belief on the board previously was that the new device simply uses a smaller antenna, or perhaps eve just a new shape. It is clear that you have have some expertise in the discipline, and that we might all benefit from your knowledge. Thanks
