*Re, * It’s never too late to learn... I think this site Impedance Matching Filter Circuit Design – LC, L and PI Filters (circuitdigest.com) (

I sent the files to a friend of mine what has a 3D printer and he said that it was warping and wasn't printing for him. Would someone out there be willing to print me a case or is there a company that

Ugg...memories of circuit analysis in college have assaulted my brain! I bet a computer can get the answers faster than me. Gotta get back to changing my tractor tire...enjoy. Scotty WD4PYT

Hello, In the Ubitx V6 documentation, it is noted that the 45 Mhz filter must see an impedance of 500 Ohm on each side. See on uBITX V6 – HF SIGNALS ( https://www.hfsignals.com/index.php/ubitx-v6/

AE9J, The hw_settings.ini file is in the data folder in the sbitx folder /home/pi/sbitx/data I suggest copying the entire folder as your customization settings and the log file are also stored

So where is this "hw_settings.ini" file? Does this file get changed by the "txcal" command? I guess I should copy that file off somewhere before I even think about changing it. Thanks.

Agreed! Also, I found the following on the sbitx group on Facebook that I think will be of interest to POTA operators: https://www.printables.com/model/819428-raspberry-pi-screen-sun-shade Thanks

And complementing this solution, I also remove the fake-hwclock ugly workaroung, that is installed by default: |apt-get remove fake-hwclock| Cheers, Rafael

It is just a matter of loading the appropriate overlay to make Linux use the installed RTC as system RTC. I use: |dtoverlay=i2c-rtc-gpio,ds1307,bus=2,i2c_gpio_sda=13,i2c_gpio_scl=6 | Then wipe the

JJ, If the address of the RTC? is 68 without the sBitx program running, you should be able to sync the RTC to the Pi. That doesn't look like the RTC address. -- Jerry Ponko, AC9NM

I wish that the sBitx had used the standard I2C overlays instead of bit-banging. Back when the sBitx first appeared, I was not convinced that the WM8731 codec and the Si5351A could not work together

Thanks for the link, Jon. This is really good info. I started to play around with some of the commands and may go further to see if I can use it in the 64bit build. This is a good way to test the RTC

Does this adafruit article bring any useful information? https://learn.adafruit.com/adding-a-real-time-clock-to-raspberry-pi Seems that this is the same / similar implimentation.

Hi Gyula, according to the info at "sbitx.net", the RTC is only accessible via the sbitx program.? Have a read here : Syncing the Real time clock – sBitx.net (

Good job JJ and Jerry, many thanks for your ongoing work with this amazing little rig. I have applied the update to your 64bit beta2 version JJ, and can confirm that it works, and to quote you: "This

I am with Evan here and would just buy a sBitx. I am having a lot of fun enhancing and extending KD8CEC for picos and teensy, ?but after buying my own sBitx, I don’t see my work ever catching up

Excellent! ?Will update both Thingiverse and GitHub. Might be a few days as I don’t have access to my development system. But it is great benefit to others! 73 Mark -- AJ6CU/7 KD8CEC 2.0, Nextion

The uBitx V6, with Nextion display and KD8CEC software, does have a screen saver mode. This is accessed via the Control Menu, LCD button. The LCD Setup screen allows setting display brightness, and

Thank you! Scotty WD4PYT

That could be. How are you powering the Pi? For the final build you should use a buck converter set to about 5.4 volts and power the pi through the GPIO pins.? With that, I had no problem picking off
