Georgy, I did not mean to hijack your message thread.? I just wanted to measure the new firmware you provided but ran into a problem and then spun out of control. I will stop posting here and will

Rainer, I can potentially use white noise; my function generator is also an ARB.? I will have to rewrite my test. As of now it is using swept sin. But you said "ALC effects"!? That is something I

Dan, can you test with white noise? This should avoid any suspected resonance or ALC effects, I plan to test the following when I get home from vacation: PC with VA software -> USB -> X6100

After some investigation I have found that there is a time varying gain of some sort from the microphone to the modulation output.? It is worse at lower frequencies but can be seen at all

Franco, i have rebuild the Kernel and was able to make a? FT8 QSO. So i think FT8 works now. Again, thanks for your and all the others Work to make the x6100 better. ? 73 de Markus, DB2ZW

Ah thanks I got you done and working 73 KQ4WGS Nemury Valladares [email protected]> wrote:

Turn off the monitor.

I am having some terrible issues when I Key the mic it come out form the speaker high pitch any help would be appreciate I am loving this firmware. 73 KQ4WGS

Turns out that the problem with FT8 TX not sending out any signal was due to this line in the sun8i codec module in the Linux kernel:

Did you ever find a solution to this? I have the same error. Side note: FT8 WSJT-X works 73

I've always heard the tale as starting with a stone rather than an axe, but so applicable in many contexts! I have been known to relay that story when discussing feature creep with new in career

There is a tale about a soldier who cooked porridge from an axe (; If you take X6100, remove STM32, replace AllWinner with FPGA, rewrite DSP functions, open the source code - you will get TRX "Brass"

I initially thought so as well. ?I did measure the function generator, and it was extremely flat. But after looking at several runs of the test using different drive levels, you can see that the

It might be due to digital filter design on the firmware. At least, when I recorded signals - they all have some audible resonance close to cut-off frequency for any frequency from 160,200, 250, 300

I found a 10uF tantalum cap I used as a DC block.? The 0.18uF I used previously was introducing some additional roll off.? I also changed to acquisition code to actually look at the FFT bin that has

Thanks for this!? I am planning on connecting a nice microphone and footswitch to the X6100 and started doing some testing.? I noticed the 300Hz lower limit on the audio and searched to see if that
