Sticky #qmx #SSB Firmware beta 1_01_003 release #qmx #ssb

 

That update 'hanging' happened with the prior two releases on a couple of my units.
I don't believe it is related to the new firmware; it is something that has always been there; just happens sometimes.? And sometimes when you put it in firmware update mode from the menu, it doesn't auto restart and bring up the drive - you have to press the power button to make it start up.

I had the same experience as Adam although I didn't wait for mine to disconnect, I just pulled power after the QMX hung.

Power cycled and booted up fine. Then I went back into firmware update to confirm the 003 version was loaded and it was there. Just to be sure, I tried to load 003 again and it hung like before.
 

Typically when I move new firmware over, after the file finishes copying, the drive disconnects, and the device reboots.? When loading 003, it hung for about 5-8min before the drive disconnected, and then it did not reboot. I had to pull power in order to get it to power back on.? Not sure this is a "bug" or circumstance related to my system and my setup.

yes, external mic
 

With this release - still external microphone must used - right?

Just tried this and was able to run calibration from the front panel with USB disconnected. Interesting results.

My QMX+ has TN0110 finals so I was expecting possible issues with calibration. When I first ran cal from Putty, three or 4 of the upper bands plotted as mostly flat lines at the top line of the graph. Most of those bands also exhibit the "
Continuous weak tones at 1KHz/1.5KHz/2Khz so I thought maybe those were affecting the calibration. Some of the tones go away when the USB cable is unplugged so I unplugged it and ran front panel calibration. I thought I was on to something because I could see full curves being plotted on the LCD for all of the bands. But when I went back to putty and looked at the curves that way, they were still flat lines at the top of the graph. So, there is a difference in plot scaling between the LCD and Putty.

I need to dig some more but it seems like running without the USB cable does make a small effect on some bands. I should have saved captures of the first calibration plots. I will have to save all of these and rerun with the USB cable attached to be sure.

Hi all

I updated the SSB beta testing webpage of the brave, here:??and released firmware version 1_01_003 to it. These are the changes:
  1. Bug fix: Initial value for noise gate samples was 100 (should be max 99) - makes no real difference but it needed to be fixed
  2. Added TX indication underlining the A character when transmitting from USB sound card in SSB mode. Note that the two possible states for this indication are a single dot (indicating PTT has been applied and now the radio is in TX mode) and the solid bar (indicating audio is being received from the PC and transmitted). There is no double-dot like there is in Digi mode indicating insufficient volume, because in SSB mode the radio transmits whatever you give it, even if the volume is low.?
  3. Bug fix: CAT command TQ1; did not cause transmit when in SSB mode. Now TQ1; and TQ0; work properly in SSB mode.?
  4. Bug fix: Prevent button presses from accidentally activating VOX, which was happening due to sound picked up from the internal (cancellation reference channel) microphone when you pressed buttons right next to it, and that prevented band change because the second click of the double click was ignored because by then the radio was in transmit mode. All fixed! Now you can click buttons however you like and when button clicks are done, VOX is temporarily disabled until your button pushing frenzy is over.?
  5. Power meter now reads Peak Envelope Power (PEP) when in SSB mode. Previously it was just reading a sampled value (NOT an average); so if the power meter was updated 10x a second, the updates would just randomly pick a value from the SSB amplitude?envelope, which was most unlikely to be its peak value.?
  6. Bug fixL Calibration hung at DAC 1300 when run on LCD. Now the calibration completes properly when run from the LCD.
Many thanks for all the feedback so far, SSB in QMX is getting better and better!
