Hi All, I have some misunderstandings on programs of JT series.
In all programs there is a function of file save that can be used to save a series of wav files in a not selectable format. I downloaded the "Basic Tutorial for WSJT 5.9+" by Joe K1JT, understand and visualize/decode the examples by the wsjt-r4336 (version 10 compiled by JTSDK-PY great SDK). The samples of JT65A are not decoded by wsjtx (version 1.5.0 r4585 by JTSDK-QT) I try use VLC and Sox (see http://sox.sourceforge.net/ and http://sourceforge.net/projects/sox/) to visualize the file formats and resamplig. The JT programs series use sampling rates different and not fully compatible. There is two base samplerates used, 44100 and 48000 multiplied by a power of 2 positive or negative. In addition the files can be 8 or 16 bits sample. WSJT accepts to decode all of "Basic Tutorial" also if samples are of 8 bits. So I save some files JT65A on HF bandswith the two programs, resample them for read with the other program. The results are strange. Yes, wsjt is optimized for for a use and wsjtx for another one, but so different results is not expected. Some messages are decoded by a program but not the other and vice versa. Next week I will try to connect to a receiver to two computers with the two programs to see the differences and avoid resampling. Not equipped for map65 using, so I cannot compare. Someone has already done these tests with JT65A ? 73's Sandro IW3RAB ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
