Yep, I added that to my software. I think I presented the code somewhere earlier. Gordon

The Emtech ZM-2 is the obvious choice for the zBITX. I have one and it is an excellent wide range tuner that you can built from a kit or buy assembled. -- 73 Bob? KD8CGH

When I started with the sbitx my first antenna was a QRPguys EFHW https://qrpguys.com/end-fed-half-wave-sota-antenna-tuner , which as advertised is kindof forgiving about wire length and has a

I?m using mine with ATU-10 and it works very nice. It would be very useful to have a tune button somewhere ?to put out a 5W CW signal. ATU-10 doesn?t tune above 10W. / Johan

Here are a few links for QRP wire antennas that I've found useful. 73 Chris

All - I am happy to announce that the 64 bit version of sBitx Toolbox has been updated. Changes in Version 2.8: * Added V3PowerCal utility (no more separate download) * Removed Screen Resizer and

An MFJ-971 seems to do the job on my ?Bitx when I’m using a badly-tuned antenna. But not as good a job as nothing and a well-tuned antenna! If you’re aiming for an EFLW, you’ll likely need a

Any recommendations for antenna tuner to match zBitx to various antennas, especially long wires? Frank KR1ZAN Garland, TX

If the "protected" cells don't fit but you want BMS protection, you could replace the battery holder with something like this. It has a full BMS inside the battery

I preemptively ordered some batteries for the zBitx, and they just arrived! Really looking forward to this new radio!

lol I managed everything apart from uploading the firmware to the Nextion. I bought another Arduino to preserve the original software. If you're successful, " I'm sure you will be" I may give it

Dave, I guess I win, I’m 72;) If you do use another Nano, remember that the calibration data is stored in the Nano EEPROM. You will need to calibrate the radio. ?Mark does have a process on the

Oops... Ok Fingers crossed.? My appeal on here for help has been fantastic but now even the help seems to be becoming more complicated the more I delve down. One or two contradictions I fear which is

This is my fear Alan but until I have it all up and running I will be like a terrier with a bone. I'm 70 so trump your 68 lol

Cheers Mark... The Nextion I have ordered is this one.... https://www.ebay.co.uk/itm/296607331848?var=594486434882 Fingers crossed..... Its a 2.8 heeding the power consumption advice. I'm thinking

As Evan as mentioned, getting the Nextion/KD8CEC software to work requires that you match the proper ".tft" file to the screen you have. If you have a mismatch, it is pretty obvious as you will see a

Looking forward to ordering one as soon as they are available.? I have the sBITX and it works well after the initial learning curve and making some setting changes. -- Dave

Hi Evan, Thanks for the links. You helped me at the time I tried to do the upgrade, I could follow most of the instructions but it started to get to complicated for me! I downloaded the Nextion

The Nextion editor is the development tool used to create the Nextion screens.? It is available from Nextion here: https://nextion.tech/nextion-editor/ Note that you may need the LTS version of the

Thank you!? It seems like the website should be clearer on this subject then.? It seems as though the bottom line is that this is a 5 Watt radio. -- Dave
