Hi All, I have a trouble with wspr 4.0 r4889 under JTSDK 2.0 Windows and Linux Cannot enable "Measure an audio frequency" button as described in http://physics.princeton.edu/pulsar/K1JT/WSPR_4.0_User.pdf appendix C, where at point 3: 3. With WSPR running in Idle mode, click Measure an audio frequency on the Advanced dialog screen
WSPR is in idle mode, but "Measure an audio frequency" button is disabled. To understand the problem I used the procedure in http://physics.princeton.edu/pulsar/K1JT/FMT_User.pdf and substitute command "fmt" with "fmtest" Very nice and useful software. In JTSDK a script is provided: C:\JTSDK\wspr\install\fmt-env.bat from the prompt I test some stations. fmtest 1170 1 1500 100 60 KOPER fmtest 4996 1 1500 100 60 RWM fmtest 9996 1 1500 100 60 RWM fmtest 14996 1 1500 100 60 RWM Manually removed few lines from fmt.all where frequency measure is not correct (eg. if all measure on 15 Mhz are in 2 Hz range, single line with high offset is inconsistent) fmtave fmt.all fcal fmtave.out I obtain all files needed and also a fcal.plt usable with gnuplot. fcal.out contain: 0.0383 -2.0686 The values depend on radio hardware project and precision of calibration. "A" value near to zero is realistic. The "B" value is the ppm error and in my case is negative, 2 Hz every MHz. In WSPR button "Read A and B from fcal.out" work and I obtain the calibration. The values inserted in WSJTX 1.6.1 also correct the frequency, but show me a final 999 when the frequency is read from radio. Selected 14076000 from list, radio goto 14.075.97(Hz unit missed on radio) WSJTX show 14,075 999 It is normal as FT857 is 10 Hz step and the calculation rounding cause this. Found also typos in http://sourceforge.net/p/wsjt/wsjt/HEAD/tree/branches/wspr/manpages/fmtest.1.txt where in lines 34 and 37 khz must be Hz Which is the trick to enable "Measure an audio frequency" button ? Which is my misunderstanding ? 73 Sandro IW3RAB ------------------------------------------------------------------------------ One dashboard for servers and applications across Physical-Virtual-Cloud Widest out-of-the-box monitoring support with 50+ applications Performance metrics, stats and reports that give you Actionable Insights Deep dive visibility with transaction tracing using APM Insight. http://ad.doubleclick.net/ddm/clk/290420510;117567292;y _______________________________________________ wsjt-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/wsjt-devel
