You probably got this hoping to not have to bring along an external battery, but do keep in mind that even with a good internal battery you are limited to 5 watts.? If you're doing any kind of digital work, that's going to speed up the discharge.??

In my experience I have tried bringing along a 3aH Bioenno battery which has provided more than enough full power for my needs.? ?I can't say I've transmitted for hours and hours as you have, but I can say I've been able to use that same battery for multiple activations without recharging.??

Since a Bioenno battery only supplies 13 volts I've only been using it for the radio.? There are certainly times I want to bring along another device powered by USB.? I found this battery which provides plenty of PD volts to power up the radio:??

You'll need this cable for the radio:


With this battery now I have something useful both for the radio and other USB-powered devices, so it justifies bringing along an extra battery.

Of course, your needs may be different.

Hello All.

This is my first post to this group, and I thought I'd post my experiences with the X6100 with respect to the battery.

I am the second owner of my X6100. The history of the radio is that it was manufactured in March 2023, purchased from a UK dealer by the original owner in May 2023, and ended up in my grubby hands in June 2023. While I've owned the radio I have been sceptical about the battery performance, or should I say lack of performance. I'm not a newcomer to LiPo cells/batteries, having used them for many years in my RC hobby.

I took the back panel off of my radio and found that the battery appears to be just one cell, it could be two cells but they would be the thinnest cells I've ever seen as the total depth of the battery is around 4mm, if that. This appears to be a newer version compared to the two cells that were originally used, stuck side-by-side on the backplate, as it is fitted length ways with the Version2? BMS board mounted at the end, and the solder tabs of the cell soldered directly to the BMS.

Since owning the radio I don't think I've managed more than 90 minutes of receive before the radio shuts down. On transmit, into a dummy load. it will shut down immediately and will only come back on when external power is applied. Hardly a self contained field radio.

I contacted Radioddity EU, they are the European Support for Xiegu, to ask their advice and their first advice was to search for replacement cells on AliExpress. I emailed them back and asked that surely they could supply a genuine Xiegu battery assembly, their reply was as I didn't buy the radio from them they had no obligation to talk to me, and the conversation ended there.

As I'm typing this my X6100 has been switched on for just under an hour from a full overnight charge, and it has just locked up, no audio, no spectrum activity, and showing a battery Voltage of 6.5Volt. Not the first time and is an easy fix.

In the past I have done similar tests as those carried out by the OP but using my calibrated bench supply. From completely flat, the charging circuit consumes 653mA which fluctuates slightly as the green LED flashes. When the LED stops flashing the current falls to around 520mA and steadily falls throughout the charging process reaching 73mA after about 7hrs. I expect the 73mA consumption is due to the green LED being on constant and a few Linux processes still running (the battery monitoring runs when it is switched off). This is very similar to the way my IC-705 charges, and the battery capacity is the same. The difference is the 705, even thought it consumes nearly the same current on receive as the X6100, runs for many hours on receive, I don't know how many as I haven't spent long enough at the bench to find out. Another difference I've noticed is that the battery in the X6100 suffers from Voltage sag where as the 705 doesn't. I l can switch the X6100 off at say 7Volt, wait 10 minutes and switch it back on and the Voltage will be back up at 7.6Volt or so. This tells me that the C rating of the LiPo's being used is not sufficient for a constant current draw of around 400mA (measured current draw on receive), this may explain why they are so thin and not suitable for use in a this radio. It could explain why Radioddity EU didn't want to talk to me about batteries, as I'm sure they've probably already gathered that their choice of batteries was a foolish mistake.

CW Decoder works ABSOLUTLY NOT more in 0.19

In the science fiction story of the Strugatsky brothers from the times of the USSR, there was an episode when a reader wrote to a scientific journal: “I have been watching underground knocking in my basement for many years now. Please explain how it happens.” So, I don’t know how to fix the “underground knocks” ((((:

_Short_ press Lock button or SPCH/Lock button on HMic

Is there a simple way to lock the frequency? The lock button next to the VFO encoder does weird things. What am I missing? I love the firmware btu.

Thanks. I will try that.

It's very easy to forget about the power slider when using wsjt-x. Every band is different. I set my cmedia output level coming in off the USB connection to about 50% on the PC, then set the slider on wsjt-x to about 1/3 of the way up. With very low power, I transmit (tune button) and check the ALC. The x6100 is backwards in terms of ALC indication and you need to get as close to 100% as possible using the slider. The R1CBU firmware is nice because the power/alc numbers are much larger on the display and alc is indicated normally - so you try to get close to 0% ALC.? I think there is a setting in WSJT-x that remembers the slider position per band.

Then I have tracked a bug to such scenario: boot, go to messages, send, play, everything works, then exit messaging app and long-press ATU to auto-tune the antenna. After this messages do not play (silence) and do not get sent (or gain is very low). Running SWR scan also disables messages.

Yes, this is an old and well-known problem, I have written about it many times. Sometimes sound playback disappears if you switch to DIG modulation. So far I have not been able to overcome this. Only restarting the BB processor helps (this happens when the application is restarted by long pressing the Lock button)

Yes when the ATU finishes there is a kerchunk also. Seems to be some kind of a systems sound.
However after some hours of trying out various options, it seems to happen only when the internal speaker is used, as the volume needs to be quite high for that.
Using headphones or powered external speaker the volume can be reduced substantially and there is no kerchunk.
Dammed if I know why the two firmwares should be different, but at least I have a solution.
And the external speaker gives better audio that the inbuilt one.

Hi Oleg,

First of all, thank you very much for your work. Some reports from me.

CW decoding does work for me, but I didn't try 0.17 to compare. It really decodes a lot of 'T' and 'E' but in general it works. It stops working when you set Filter low to 0Hz and starts working again when you set it higher.

First X6100 boot with freshly flashed SD card results with spectrum filling full height and no waterfall, but there is reception. Changing RF gain does nothing to the display. After reboot, everything works as expected.

There is something fishy with voice message recording - it does not record and does not play on the radio and does not tx out of the box - on the first boot. Also, seems rec gain is too high out of the box. After several restarts though I have managed to record a decent message and was able to play and TX it. Then I have tracked a bug to such scenario: boot, go to messages, send, play, everything works, then exit messaging app and long-press ATU to auto-tune the antenna. After this messages do not play (silence) and do not get sent (or gain is very low). Running SWR scan also disables messages.

While TXing message, HMic is active.

When you delete the last message, it is not cleared from the list.

Playback and record sliders in settings have a max value that's in the middle of the slider. I.e. if you set gain to max (full slider), you'll find it in the middle next time you switch to settings.

When I connect earphones to S/P port and Push PTT on HMic to transmit, I hear myself in earphones but pitch-shifted down. Event though Moni Level is set to 0. When I play recorded message, I hear normal voice, but while tx of voice message I also can hear pitch-shifted down ogre voice mixed with the recording. I have noticed, this is related to output power - more power, stronger the ogre voice during tx.

I have experienced spectrum and waterfall hangups several times. It seems to be related to VCO frequency display overlay. If I scroll too fast or the radio experiences a hickup due to switching to different ATU config or a very strong QRM happening and overloading the frontend while scrolling over frequencies fast, spectrum gets stuck and waterfall is not scrolling anymore. It updates just when changing frequency and then stops again. I have suspected frequency display overlay, so I switched it off and did not experience this problem after that.

Hope these bug reports will help, let me know if you need more details. Once again, thank you for your hard work. LY1MIC 73.

I got my new X 6100 yesterday and set everything up for CW and FT 8 using external 13.5 V power supply. I made several FT8 contacts yesterday afternoon. This morning I turned on the new X 6100 using the internal battery only. I set up preset messages for CW and made a few contacts on FT8. Now when?X 6100 goes into transmit using WSJT-X, the transmit is only one bar, no output and the SWR shows nothing (no line). I put it in CW mode , and it behaves normally . Can anybody give me some advice on what to do? Thanks in advance.

I work with this radio in the fields. Only with your own firmware. If it was I would have noticed.
I checked now. I do not have that.

Hello all.
Tried the R1CBU f/ware version 0.19.0.
Very impressive, however after playing with it for a while? have an odd problem.
Using the supplied Xiegu fist mike, when the PTT is released there is an extremely loud kerchunk from the radio.
Does not happen with the installed Xiegu firmware.
Anyone any thoughts ?

I finally received my dummy load , made some tests and the transceiver is working normally ... seemed to be an RF issue.. problem SOLVED? with an RF choke that I built following the instructions that I found at hf kits.com... thank you all for all your opinions and help !!!
