Added support for gen_packets. **** NOTE THAN THE MARK AND SPACE FREQUENCIES ARE BACKWARDS in gen_tone.c. Lines 228-229 correctly set f1_change_per_sample to the MARK frequency and f2_change_per_sample the space frequency. Line 383, however, sends MARK on 0 and SPACE on 1: tone_phase[chan] += dat ? f2_change_per_sample[chan] : f1_change_per_sample[chan]; As such, you have to generate packets like this: gen_packets -e R -m 1800 -s 1200 -o test.wav eotd.data EOTD input to the program consists of lines of 8 byte packets in HCB+ATAD format; i.e. the format that direwolf appends to the decoded packet. Ex: 81 b0 32 fb 31 23 73 8f A new option has been added to atest: -e type. That enables EOTD generation and the 'type' signifies 'R'ear to front or 'F'ront to rear decoding. Using "atest -B EOTD test.wav" the above packet decodes to: DECODED[1] 0:00.123 EOTD audio level = 49(30/31) [0] EOTD>APDW16:{DRREAR>FRONT:ts=2022-04-07T10:02:00.350,chain=ONLY,block=BASIC,devbat=OK,msgid=ONEWAY,unit_addr=18151,brake_status=GO(49 psig),disc_bits=f6,valve=OPERATIONAL,confirm=UPDATE,disc_bit_1=1,motion=STOPPED/NOT_MONITORED,light_batt=OK/NOT_MONITORED,light=ON,hex=81 b0 32 fb 31 23 73 8f 2022-04-07 14:03:49 +00:00			`#ifndef __EOTD_SEND_H`
