I updated the?SSB?beta?testing webpage of the brave, here:??and released?firmware?version?1_01_005 to it.?
There are TWO changes only.?
Firstly, I have made many changes to the SSB Calibration (phase pre-distortion self-measurement). These improve the robustness of the calibration. I made changes both to the way the calibration itself runs, as well as searching different configurations of the radio while running the configuration. On my QMX+ here it now runs from 160m through to 6m and completes all successfully, with the very minor exception of 160m which only gets as far as DAC 2300, so *almost* there,?just not quite and it won't matter. All others run all the way to the end (DAC 2600 or so, on a 12V supply). Additionally I applied a little?Chaikin algorithm smoothing to the curves. You will notice some additional debug information printed on the screen on some bands on the terminal version of the calibration and the calibration will take slightly longer; this is the system trying to determine feasible calibration configurations on "difficult" bands.?
Secondly, I have added a configuration in the System Config screen (accessible on both the terminal and the LCD). This is a "list" selection so use the left/right arrows to select a value in the terminal, or the Tune rotary encoder to select a value when adjusting it on the LCD. The possible values are:
USB Audio sound card and ONE serial port, as previous configurations
USB Audio sound card plus TWO serial ports
USB Audio sound card plus THREE serial ports and potential future USB Flash drive
Only the third of these makes use of ghost USB endpoints.?
Note that I also discovered an error in the USB Hub Device Configuration Descriptor in the area of the potential future USB Flash drive. On my Linux system it just worked anyway, but it's possible different Operating Systems are more fussy. I am very curious to hear, particularly from people with Windows (even Win 7 Ludwig), what you experience for each of these configurations. Even if you already tried it on 1_01_004 please try again which each configuration in 1_01_005 as it will provide very useful information. They all work here, but my system is Linux.?
