The digital data is proviced on connections that have nothing to do with the connections for the analog speaker audio or the analog microphone audio. In addition to the audio wires (that aren't included in the programming cable since they are not necessary to have for programming) and the data wires, there is even a connection that provides DC voltage (5V or 3.3V depending on the radio) to power external devices. http://www.miklor.com/COM/UV_Technical.php#spkrmic Jim KC9HI _______________________________________________ chirp_users mailing list chirp_users@intrepid.danplanet.com http://intrepid.danplanet.com/mailman/listinfo/chirp_users This message was sent to arch...@mail-archive.com at arch...@mail-archive.com To unsubscribe, send an email to chirp_users-unsubscr...@intrepid.danplanet.com
