Fantastic job. Congratulations for the work.

?

It works great.

?

I have an idea for next versions: auto send FT8 receptions to pskreporter.info

Thanks Mike.

I'm using my trusty MFJ 868B Big Meter. It always seems to be accurate with all my radios.

Just looked at your youtube video. At 21.074 I get birdies at exactly the same place as your noises. However, Not as strong.

Both 0.28 and original Xiegu firmware have those birdies at the same signal strength on mine.

?

I've been checking it out. At 10 Watts and the amp off it transmits 10 W.? Looking at the waterfall, I could see the signal.

I switched on the amp and switched off the PA. The amp reported ~3 Watts.? I don't think that reflects the actual power since the signal is just going through the amp. FWIW, the waterfall showed the same as when the amp was off.

I don't know that the waterfall shows the TRANSMIT power, but I really do think you are getting the full 10 W whether the amp is off or on.

I have a strong noise on all bands when using Battery with Alternative Firmware v0.028.0

-Problem is shown on RX.

-I don't see that on TX but I hear my own voice on the speaker if I call SSB. Monitoring level is at 0.

-Shows up at beginning of the band and at the end.

-With or without antenna.

-Noise goes to minimal, but still there, when the screen dims out after a few seconds not touching the VFO or any button in the radio.

-Goes up again, as soon as I wake up the radio by touching the VFO or any other button.

-Goes off as soon as I plug in the external power.

?

In brief: The problem is not there or does not show up if using external power.

With Battery the radio shows 7.8V on the screen.

With external power shows 13.6V on the screen

I made a video that shows the problem live for you to see.

?

Suggestions what could be happening are welcome.?

The name "Shadow charging" was invented by Oleg, after my suggestion of the feature.

Stock fw only had options Charger On or Charger Off.

If you wanted to charge the battery with the supplied external charger you had to turn "Charger On" in the settings each time you turned the radio off.

Likewise you had to go to settings and turn "Charging Off" before transmitting, as it was recommended to NOT CHARGE BATTERIES WHILE TRANSMITTING.

I suggested the feature of "automatically turning charging on when powering radio of" and vice versa.

And Oleg implemented it ?

I run 10w out of the X6100 with the amplifier on, and the pa set to off with no issues. I have not tried with the amplifier turned completely off. I am sure there would be losses going through the amp when off, but I have not measured it.

Georgy, I understand 100% and, as you can see in the comments here, there are still bugs with FT8 and CW that I need to figure out.

?

This said, I think you may still want to look at the patch I wrote for 'x6100_gui' to make it compile with gcc 14 without errors: - there were a couple of minor issues, but in one case the variable 'qth_val' is defined as an array of pointers to char, instead of a char array (i.e. a C string).

Regarding the charging of the internal battery of the X6100, you may want to take a look at my post ten or so days ago: /g/xiegu-x6100/message/6468 and perhaps collect some information on the battery charge process by running the 'monitor-charging' Python script while the X6100 is charging (runs on Linux and needs the USB cable connected to the 'DEV' port).

?

These are my findings from that post:

- in my case too the LED stayed solid green while the battery was charging, so I don't know if it really matters (as long as it is not completely off)

- if you look at the plot of the battery voltage and charge vs time, the logic of the internal charger of the X6100 is very simple: constant current (about 177mA) until the voltage reaches about 8.43V, then constant voltage. At constant voltage it looks like the battery is still being charged at about 35mA

- I am not a battery expert, but it looks like the batteries (there are actually two of them in the X6100 connected in series) can be overcharged above 6000mAh - in my case the firmware was showing up to 6600mAh, but looking at that plot I suspect it could have gone even higher

Hi Gregory, this firmware is amazing!? Here is an idea for some of the developers.? What about some limited JS8 functionality.? I find JS8 helpful when doing POTA/SOTA and there is no cell signal to spot.? Or the ability to send JS8 to APRS for SMS messages.? Some sample strings that can be pre-loaded and edited.? With the radio already doing FT8, I am sure its more than capable.

@APRSIS CMD :APSPOT ? :! POTA K-TEST 7100 SSB TEST SPOT via APSPOT over JS8

@APRSIS CMD :SMS ? ? ?:@5555555555 TESTING JS8 TO SMS{1

Also, I have found these APRS messages over JS8 seem to be very particular on # of spaces and things like that.

Anyway, just an idea that maybe makes it on to the backlog.

Just some observations:
* Output power with external power supply jumps to 7W, without - only to 5W (looks like limiting)
* ALC always 100 without external power supply.
* Waterfall without external power supply looks dirty a bit.

?

I would check next:

* connect headphones to s/p,

* set monitor to 0 (here you can see audio spectrum/scope).

It might be an power line? interference from output audio amplifier to input, not sure.

Perhaps, if Georgy is interested, we could use the newer buildroot for some future version of the X6100 R1CBU/R2RFE firmware instead of having two versions.

I guess, I'll use your version in one of the future build, but maybe not for the next one. I'm stuck in refactoring and falling deeper and deeper))

Sounds like RF getting back into the radio. Have you tried it with a dummy load or another antenna? You might need more choking in the cables. I see one on each cable but that may not be enough.

Plugging in the DC cable might be acting as some extra grounding.

You can also go into radio settings 1 and turn moni level down to 0 as a temporary solution.

?

My original x6100 led flashed while charging. Recently purchased a replacement after the old one developed a fault. The led stays on while charging with the new one but it does charge. Mine charges with original and R1CBU firmware. You may have a fault with the battery or charging circuit.

Hi!

?

It's very nice to see development still going strong..

I have been away from the hacking scene and radio in general for a while, it makes me happy to see the projects have taken off. Thanks for doing this.

?

This has far surpassed what I could envision. My only contributions were the very basics of the LCD driver (I did a skeleton of a DRM driver and Oleg reverse engineered all the register values), and did the very basic to get a buildroot started. Again Oleg did many fine tuning on the .dtb and other settings. He the mostly did the library for interfacing with the uC and then all the well known firmware he publishes now.

?

It does sadden me to see some of the things didn't go public. After all, there is something called the GPL. I wish that would change.

?

Anyway, thanks for keeping the project going.

73, Rui

This is very interesting.

?

This is very much the problem I am having as well, but with stock firmware. I just created another thread about a problem with audio on Tx on battery and it might be due to low voltage of the battery. The led also stays permanently on... Very interesting... Wonder if there is something on with the charging circuitry or if it needs some way to be reset or something...

?

It has crossed my mind to maybe try and open the radio, charge the battery with an external charger, and then close it to see if the BMS would wake up. Maybe too low of a voltage of it to even charge?

?

I would need new screws, the ones on my radio are already worn out hehe.

?

So, ideas to reset the BMS? Anything is welcome.

Hi everyone,

?

My Xiegu X6100 has a very weird issue. If it's running on an external power supply it works fine but if it's working on battery then it makes an unbearable noise on Tx.

I recorded a small video demonstrating the problem:

?

Does anybody have any idea what could be the issue?

?

Any tips appreciated.

?

Thank you, and 73.

Hi to all,

?

I've noticed some problems regarding charging X6100 internal battery while using firmware R1CBU/R2RFE 0.28.

?

Battery was weak (7V or so) so I decided to charge overnight with OEM charger unit. Switched "charger on" in the R1BCU firmware, set power off and then inserted OEM charger unit. Green LED starts, but not flashing, was permanently on. (This normally means "battery full"...) But left it charging anyway.

?

Next day when I get the charger off and started the X6100, the internal battery was completely empty. By switching off the DC, the transceiver suddenly shut down.

So tried new charge cycle using OEM firmware (1.1.9 / 1.1.8), but with the same result. Green LED is still glowing permanently and the battery does not charge. Power supply shows a consumption of only 0.9 Watts, too less.

?

What happenend? Battery damaged while charging? Issue with battery management??

Firmware problem? Should we set "charge on" with R1CBU or OEM firmware or both??

What means "charger shadow" in the R1BCU fimware?

?

Anyone out there who has experienced such a case?

?

Thanks for any advice

Markus,

thanks for giving it a try and reporting the issue with FT8 and CW decoding.

I am going to look at that over the weekend.

?

Jason,

since Markus was able to build it on Debian, which is very similar to Ubuntu (I use Fedora here), if you post the exact error message you had when trying to build it, we might be able to help you. Perhaps it is just a missing dependency.

Once we figure out the problem, I'll also add a note about that in the README.

?
