I see lots of nice new toys, Alberto. The AM sounds good. After a little rest, could you think about the following:
(1) with SDR-IQ wav files, there's no way to know what frequency is where in the display. That can be quite a mess when the recording is full of stations on both 9 and 10 kHz plans. This could be fixed by reading the center frequency (bytes 32, 33, and 34) (LSB to MSB respectively) from the auxi chunk of the wav file and using it to "grid" the display every 5 or 10 kHz. (2) The ECSS is quite often not usable for me when the desired carrier is weak and close to a strong carrier. The ECSS seems to lock onto the strong carrier as if it is still in the capture range. I found it almost impossible to get ECSS tuned to 1089 (in LSB mode) with a strong station on 1090, even thugh the 1089 station was strong enough to produce usable audio in plain LSB mode. Chuck P.S. I promised you some Matlab files for a Costas loop. I haven't forgotten. --- In [email protected], Alberto I2PHD <[EMAIL PROTECTED]> wrote: > > I have just released V1.30 of Winrad, downloadable from > http://www.weaksignals.com > > The main changes from V1.25 are : > > - New AM, ECSS demodulators > - With ECSS the user can select between the LSB, the USB or both > - Correct management of WAV files of 16, 24 bit integers and 32 bit floats > - New DRM mode with output bandwidth of 12 kHz > - Option to select among multiple ExtIO DLLs > - CPU load reduction by placing the fractional resampler after a > dynamically reconfigurable prescaler > - The status bar for WAV playback is now clickable, to fast forward or > fast rewind the playback > - The WAV file played back has now its name displayed > - One to four samples delay insertable on the left or on the right > channel, to accommodate for the EMU-1212M > - Real time display of the frequency and the dB level that follows the > mouse cursor > - AGC hang time slightly lengthened. > - Speed slider curve changed > - Input selection is now a radio-button > - Volume lock status is now remembered between sessions > - Mute button added > - Past expiry date, the program still works, only a warning is issued > - Some optimizations and errors correction here and there > > Reports welcome, thanks > > Happy New Year ! > > 73 Alberto I2PHD >
