QDX firmware 1_06_004 beta


Hans Summers
 

Hi all

Here you can find a version 1_06_004 beta:

The version contains the following changes:
  1. When bias mA is 5mA, disable PIN diode forward bias SMPS system completely (results in around 4mA default bias current).
  2. Change default 80m Frequency min to 3200000.
  3. Add "Night mode" parameter to configuration screen - when enabled, it makes panel LED very dim, by defining the GPIO pin with internal pullup to light the LED. It's dim but if the QDX is on a shelf in front of you and not in too bright lighting, it will be visible.
  4. Now successful TX is a 1Hz pulsating indication, the LED current actually follows a 1Hz sinewave; meanwhile the spacing between the 2 blinks in "audio insufficient" error reporting mode is now 0.2 seconds, wider spaced for easier counting
  5. Changed minimum TX freq from 300kHz to 75kHz (to allow 2200m operation). Note: receive quadrature for 2200m is not done yet. 
  6. Changed length of band name in the Band Config screen to 4 digits (to allow 2200m operation)
  7. Bug fix: Qn; CAT command return string length is now longer to fit larger numbers

Hans,
Thanks for the quick update!
I'm using the night mode, it is dim! It will take a little getting used to.
It's a very good addition to the firmware.

Hans,

Any chance of enabling the Split and second VFO operations?

How about the pulsating sinewave brightness 1Hz LED flash during transmit, and the slower blink once or twice error indication? Do the folks that found the blinks difficult to count like this way better?

Does "Night mode" work with a Rev. 3 PCB as well?

With night mode and lower LED brightness I think blinking is better than pulsating. BUT, in "day" mode or full brightness, pulsating works better for me.
Blinking grabs your attention. Pulsation is more relaxed. Unfortunately there' now clear winner here.

Hello Stefan

Night mode and all other changes in 1_06 work on all PCB revisions.

Will load the blob on Friday and give it a whirl.  Thanks Hans!  Looking forward to 2200 m also.  We have a specific application for that on Rx here in the US outside of Ham radio.

I am still far from convinced of the need for this, but I will enable it to keep the troops happy.

Split (mode THANKS) works very well when the fox calls  "CQ UP 1"  (1 kHz for example) keeps the pileup off the fox so all hounds (troops :>) can hear the fox

John,

According to the manual WSJT-X has two ways of working split without the radio contributing. Basic no split changes the audio frequency, not always ideal, but "Fake it" tunes the radio.

Alan,

For Wsjtx, yet it isn't needed. Not all people live in FT8 land either.

Hans,
Your the Best! 
A nice surprise to explore for the QDX.

Anyone using QDX on Top Band ?

Cliff,

Perhaps I should have asked Hans why he seemed reluctant to add split/extra VFO.
I must be missing something.
Or, why do you think it is necessary?

 re SPLIT es 'fox-s'

Lack of articulation on my part
      the WSJT-X fox ; >(  I've  'never' been there

I should have said 
   ...when the ((CW)) fox calls  "CQ UP 1...
Which implies he is running split
CW tip ...
A wise ole fox starts from the top of the pileup es works down

Alan,

Hans will have to answer that question himself. I can guess, but I don't want to put words in his mouth.

Is it critical to using the QDX, no. Is it necessary, it depends on what you are doing with it. Is it useful, yes, at least for some of us. Many hams never use it, either because they never do anything that requires it or they don't know how to use it.

I use fldigi a lot and having the ease to switch VFOs is handy. Any contest or DX Exhibitions usually run split. It is far easier to set the TX freq in one VFO and the RX in the other and have the rig switch automatically by using the split function for transmitting. One can emulate that depending on how wide the freq. split is with built in fldigi functions, but again operating split just makes life so much easier. Is it used a lot, no, but when needed is very useful. BTW, the Wsjtx docs recommend using it if the rig supports it so for them it maybe means less stuff to do to "fake it", I don't know their reasons.

in Fox mode, the fox will simply NOT respond to calls below
1000Hz offset ... when the fox responds to you, the sw
changes YOUR offset audio to the channel 'your fox' is on...
this should be done IN the software [WSJT-X] in 'fake it'
mode. OR the sw will send a CAT command to the tx to
change freq in 'split' mode.

Thanks Christ for that !!!

FT8'ers are nothing more than shoot 'em gamers wreaking RF anarchy on the rest of us..
