[linrad] linrad-02.39
Hello Leif i guess that Ermanno, IK7EZN has already tolt you, regarding the bug that i found on last 02.39 release. It's a minor bug, because all the rest seems to work properly. When i try to change the freq. trough the arrows all crashes. Otherwise if i do it, just writing by hand all is ok. 73' de IK2DDR,Francesco No virus found in this outgoing message.

[linrad] Linrad-02.39
Hi All, Linrad-02.39 can do calibration from recorded files, both .wav files and files in Linrads own format. This feature is intended to allow me to receive calibration files from various hardwares in order to check that the routines work as intended. There is now a new page about calibration in Linrad: http://www.sm5bsz.com/linuxdsp/flat/ampcal.htm An ordinary function generator that produces a square wave can be used for calibration on HF bands. The link has several calibration files that you might download to try what happens when you do different things. (If your pulse generator is phase stable, the spectrum you will see on the linrad screen will be sharp lines at the overtones of your square wave - but that does not affect calibration.) Linrad-02.39 also has an automatic spur cancellation routine that can locate hundreds of spurs and place notch filters on them all. For details, look here: http://www.sm5bsz.com/linuxdsp/spur/autospur.htm There are many changes in Linrad since 02-35 which is still "latest version" on the "Linrad Home Page." I have not had much feed-back on whether the changes in users.c and users_tr.c have caused problems or if there have been other difficulties. Please test Linrad-02.39 and verify that nothing that was working well before is still ok. I think that the advantages with 02-39 over 02.35 motivate a change at the "Linrad Home Page", but I do not want to give problems to newcomers. I am still looking for "interesting" interference situations. You may have seen "Reserved for blanker" in the baseband graph. This is a routine that should help against lightening crashes on HF bands and perhaps in other situations where interference pulses are not local and therefore suffer from multi-path propagation. Is there NOBODY on this list who ever tries to copy a signal but has big difficulties due to interference of some kind (or in SSB has a too low S/N) ??? I am very interested in recordings of marginal "copy" or "no copy" in CW or SSB. Maybe DSP could improve :-) 73 Leif / SM5BSZ # This message is sent to you because you are subscribed to the mailing list .
