High-Speed SoundModem v0.21b changes: - Added GOMX-3 9600bd mode. SoundModem v1.00 changes: - Added "DW QPSK 2400bd" and "DW 8PSK 4800bd" Direwolf compatible modes. The carrier frequency must be "1800Hz" (for a full compatibility with Direwolf). High-Speed SoundModem v0.19b changes: - Added "Full duplex" mode.

It can be useful for extreme condition, when your signal is close to SNR limit and your radio has frequency response correction of transmitting signal.

SoundModem v0.84b changes: - Limited length of frame for "Memory-ARQ" and "Single Bit" recovery operations according to the size of the AX.25 protocol. It may reduce CPU load and memory usage while blocking QRM. SoundModem v0.83b changes: - Added 12 dB PreEmphasis filter. - Added 3 parallel decoders with NONE, 6 and 12 dB preemphasised signal. By default this option is ENABLED ("PreEmphasis filters - All" in "Modems" menu). On both WA8LMF's Track1 and Track2 records 1021 frames are decoded. - Fixed some minor bugs. SoundModem v0.81b changes: - Added QPSK 2400, 3600 and 4800 baud modes. Note: For QPSK 4800 optimal carrier frequency is ~2600-2700hz High-Speed SoundModem v0.03b changes: - Changed LPF filter in HAPN 4800 baud mode. - Little code optimization. - Fixed some minor bugs. SoundModem v0.80b changes: - Added new BPSK 2400 baud modem. Note: For BPSK 2400 optimal carrier frequency is ~2600-2700hz - Little code optimization. - Fixed some minor bugs. High-Speed SoundModem v0.02b changes: - Changed name of the project. - Added new Manchester 1200-7200 and HAPN 4800 baud modes. - Reduced CPU load. SoundModem v0.78b changes: - Added new BPSK 300-1200 baud modes. - Reduced CPU load. G3RUH SoundModem v0.17b changes: - Added the same main features and improvements as in the previous AFSK versions. SoundModem v0.72b changes: - Added the KISS ACKMODE support. SoundModem v0.71b changes: - Fixed "Frame Collector" operation with MAXFRAME greater than 4 and IPOLL frames. By default it supports up to 6 frames into collector's buffer now. - Added "TXFrmMode" option (that was available in 9k6/19k2 version). It allows to select the transmission mode of the frames. If set "TXFrmMode=1" then it will repeat only one frame on each of REJ acks. It can be useful in poor condition jointly with MAXFRAME up to 4. If another station uses a TNC which can operate with "Frame Collector" this option can improve a performance, especially on HF. If set "TXFrmMode=0" then it will always repeat the block of the frames, of which the number is limited by MAXFRAME. It can improve the efficiency in good condition. Especially with TNCs without "Frame Collector" function. By default this value is "1". SoundModem v0.69b changes: - Improved DCD reaction on the AX.25 flags and zeros stream. - Changed default filters settings for the modems. - Added KISS TCP-Server. - Added KISS Optimization. - Added transcription of NETROM and IP traffic in the monitor window. - Added some changes in L2 protocol. - Added IPOLL frames. - Fixed RNR frames processing. - Fixed waterfall bug under Linux (WINE). - Fixed some inessential errors. G3RUH SoundModem v0.16b changes: - Reduced CPU load. - Changed samplerate to 48000 by default. - Added 19200 baud G3RUH modem. - Added some features from latest SoundModem version. - Added "Non-AX25 filter" option. It blocks non-AX25 traffic through AGW interface SoundModem v0.57b changes: - Reduced CPU load. - Added option that disable waterfall in minimized state. - Added option of the application priority that improves the work of the modem during peaks of CPU load (decreased gaps and stuttering sound during transmission). SoundModem v0.52b changes: - Improved MEM-recovery feature. That tries to recover corrupted frame from the last frames buffer. It may help if the frames are often repeated, e.g. supervisory frames. You can change the number of last packets in the INI file (by default is "MEMRecovery=100"). Higher value may help on a very noisy path. If you don't need to receive the short non-AX25 frames you can limit minimal length of frame to 17 ("RawPktMinLen=17"). It will reduce the accumulation of unnecessary frames in the buffer. SoundModem v0.51b changes: - Limited the number of bits for bit recovery operation (only for undefined state at three different levels of threshold comparator). WARNING! Test showed this option may cause additional erroneous CRC collisions, so use it at your own risk. By default is OFF SoundModem v0.50b changes: - Added single bit recovery feature. - Fixed transmission non-AX.25 frames to application (see option "NonAX25Frm" in the INI file). SoundModem v0.49b changes: - Improved RX-part of the modem (improved ATC and added interpolation). - Improved DCD for 1200 and 2400 baud. - Fixed some bugs in the AX.25 L2-layer protocol. - Expanded features for non-standard AX.25 frames for SAT-operations. SoundModem v0.45b changes: - Improved compatibility with the AGWPE and MixW AX.25 Protocol (reduction of REJ collisions) and fixed some small bugs. - Added "6dB Pre-Emphasis filter" option. Pre-Emphasis filter it's a high-pass filter that emphasizes the high frequencies in the audio spectrum. Preemphasis increases the level of high frequencies by 6dB per octave. It might help to receive signals at 1200 and 2400 baud if the frequency response of the receiver is not a "flat". - Added "UTCTime" option for indicate the time in UTC format. (1=On / 0=Off). - Added "NRMonitorLines" option for limit number of lines "Monitor" window (10-65535). SoundModem v0.44b changes: - Changed sound output in the SCO mode (now works in mono). - Changed default settings for single port configuration. - Added 2400 baud modem in the list. - Added "ExcludeCallsigns", "ExcludeAPRSFrmType" options for blocking unwanted traffic. SoundModem v0.43b changes: - Some changes of L2-protocol. SoundModem v0.42b changes: - Changed AX.25 parameters in INI file for each channel. - Added color monitor. - Fixed bug for outgoing connection with unregistered callsigns.
