CubeBug-1 PolySat-Team [2nd May 2013] CalPoly (California Polytechnic State University) could receive as a wav file from CubeBug-1. I downloaded this file "CalPoly_cubebugpacket_1900_4_30.wav.gz" from Dropbox site. Also this shorten file posted on JA0CAW's blog by him. I could decode it using MixW and Soundmodem at the same time. Tnx.> DK3WN, JA0CAW CubeBug-1 replay #1 [3rd May 2013] CubeBug-1 wav --> MixW --> OnlineKiss --> KissTerm CubeBug-1 replay #2 [4th May 2013] CubeBug-1 wav --> Soundmodem --> Agw_Online_Kiss Soundmodem.ini [13 May 2013] RXsampleRate=22050 or 44100 in "soundmodem.ini" CalPoly (California Polytechnic State University) received file CubeBUG-1_CalPoly_30042013_1900-2.wav SR=11025 SR=22050 SR=44100 CubeBug-1 replay #3 [20 May 2013] I could decode the wav file received by JA6PL setting "CubeBug-1 wav --> MixW". CubeBug-1 replay #4 [7 Sep 2013] Soundmodem_1k2 was updated to Ver0.52b. > SCM 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. > > SCM 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 > > SCM v0.50b changes: > - Added single bit recovery feature > - Fixed transmission non-AX.25 frames to application (see option "NonAX25Frm" in the INI file) > > SCM v0.49b changes: > - Improved RX-part of the modem (improved ATC and added interpolation) > - Improved DCD for 1200 and 2400 bauds > - Fixed some bugs in the AX.25 L2-layer protocol > - Expanded features for non-standard AX.25 frames for SAT-operations. > > SCM v0.45b changes: > - 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 bauds 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). > - Improved compatibility with the AGWPE and MixW AX.25 Protocol (reduction of REJ collisions) > and fixed some small bugs. Settings: 'RXSampleRate=11025' in 'Soundmodem.ini' 'BPF Taps=64' and 'LPF Taps=32' in 'Modem settings' Test wav: CubeBUG-1_CalPoly_30042013_1900-2.wav of California Polytechnic State University. It is possible in these settings to improve the decode of CubeBug-1 signal as follows.
