[wsjt-devel] Something broken
Hi all, Sorry to say, I seem to have broken something in the way double-click decodes are done. I'll look into it tomorrow. -- Joe, K1JT -- Dive into the World of Parallel Programming.

Re: [wsjt-devel] WSJT-X - Wide Graph: Spectral Display Enhancement Request
Doesn't the "Flatten" box do that for you? I'm looking here right now at a JT9 signal with side lobes that has an 11dB peak and -25dB on the side lobes which I can see on the Cumulative graph. So that's a 36dB difference visible and it has all the appearance of being clamped. Are you looking for more amplitude on the low level signals? So doing another non-linear scaling would amplify the lower signal levels? Mike W9MDB -Original Message- From: Paul DU2/WA8UGN [mailto:keat...@msn.com] Sent: Wednesday, February 04, 2015 9:21 PM To: wsjt-devel@lists.sourceforge.net Subject: [wsjt-devel] WSJT-X - Wide Graph: Spectral Display Enhancement Request Hello Developers: If not already on the "To Do" list, would you consider the following suggested "improvement" for the spectral display in Wide Graph? The waterfall is excellent - I only hope that this suggestion doesn't have to impair the waterfall display in any way just to enhance the spectral display. The version of WSJT-X that I am currently using (v1.5.0-devel r4848) allows for three selections of data for the spectral display: "Current," "Cumulative," and "Linear Avg." Of the three, "Linear Avg" is the only selection to have the baseline trace clamped at a specific level, where it remains regardless of input signal levels, 60-second resets, and the like. It's a nice solid line across the spectrum with signal representations being the only variations. The other two selections are not clamped, but are free to venture up and down the vertical graduals. The trace's movement can be caused by most anything - noise, signal, setting of volume-related controls, etc. Most disconcerting is the downward movement of the trace that occurs when a very strong signal is present - with the trace sometimes leaving the display at the bottom of the graph. This also causes the waterfall to "go dark" for those portions of the spectrum close to the very strong signal. Having two such signals at either end of the spectrum often results in only those two signals appearing on the waterfall with the rest of the graphic display blanked out (other weak to medium-strong signals are blanked out). MY REQUEST: For the "Current" and "Cumulative" selections, is it possible to have the spectrum display's baseline trace appear clamped to a specific level on the display? Having the baseline appear clamped for these two selections, similar to the "Linear Avg" selection, would produce a cleaner representation of the spectrum and could eliminate the blanking of other signals on the waterfall when accompanied by a very strong signal. I ask this so as to obtain the best information from the Wide Graph display that I can. I know that the bandpass of the filtered audio input doesn't change with the introduction of a very strong signal - it's a constant, more or less. Plus, I already know the effects that a very strong signal will have on weaker signals within the bandpass - my ears let me know. Thanks for your consideration (and, hopefully, implementation).

Details on the file locations for the current WSJT-X are in the User Guide: http://www.physics.princeton.edu/pulsar/K1JT/wsjtx-doc/wsjtx-main.html#PLATFORM also available from the application "Help" menu button, both online and offline. I would recommend ether using Greg KI7MT's KVASD installer to get a current KVASD or set the CMake option WSJT_INCLUDE_KVASD to ON and rebuild to automatically download and install the latest KVASD for your platform. > > The cmake process in wsprx generates a spurious reference to > a windows DLL.
