KD7LMO - V1.03 HF-APRS Source Code// // Name: psk31beacon.c // // // Revision History: // // M. Gray 21 Dec 2003 V1.00 Initial release. // // M. Gray 6 Jan 2004 V1.01 Pre-flight release that includes all functions. // // M. Gray 17 Jun 2004 V1.02 ANSR-19 test flight // // M. Gray 26 Jun 2004 V1.03 Changed 1200 bps, A-FSK APRS status packet to include web link, // removed 'Balloon' from 3rd line of PSK-31 text, // modified I/O to support more accurate 1-PPS for TCXO correction, and // added list of 3 frequencies and amplitudes for PSK-31 band tuning. // // // COPYRIGHT (c) 2001-2004 Michael Gray, KD7LMO // // This program is free software; you can redistribute it and/or modify // it under the terms of the GNU General Public License as published by // the Free Software Foundation; either version 2 of the License, or // (at your option) any later version. // // This program is distributed in the hope that it will be useful, // but WITHOUT ANY WARRANTY; without even the implied warranty of // MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
