An interesting post here - https://www.eevblog.com/forum/projects/diy-metcal-13-56-mhz-rf-supply/msg324871/#msg324871 Metcal soldering irons use 13.56 Mhz RF power - the tips are coated with a materia

Good evening, I am a bit new in this field and I do not have all the material for in-depth analysis My first question is whether you can emulate a spectrum analyzer with an oscilloscope and an HF gene

Reference the v3 I tried to calibrate my uBitz3 by computer but see that there are several hurdles to understand before I can communicate with the Raduino. Can anyone tell me the baud rates for the PC

while monitoring the ubitx with a sdr, out of the blue every time the t/r pulls there are 4 spikes on the sdr analyzer, 2 above and 2 below the main frequency the rig was running approx 5 watts into a

I decided to give a try to adjusting the si5351 offset using a external PPS signal connected to the arduino. Has anyone written code for this? Rafael

My uBitx V6 worked well for a few hours, then the power output stopped. (I smelled some smoke for a few seconds, and shut down, but it was too late.) I then could still hear a weak signal on my other

Using a solderless breadboard, I cobbled together a Raduino board mock-up to test out my firmware conversion to the Nano Every: Arduino Nano Every 2.8" ILI9341 TFT touchscreen display SI5351 breakout

I'm setting up another radio with a 3 pin XLR dynamic microphone setup. I'm just wondering if someone has managed to set up a uBITX with one. -- '72 Aaron Scott The K5ATG Blog Mid-Del Amateur Radio Cl

Ubitx v6.1 with WSJT-x v2.1.2 (also tried latest rc3 and 2.2.2) The test cat button is green but test ptt is red The only rig that works is FT-847UNI - 817,857,897 all fail Changing the Freq changes n

Looks like we have a new mainstream microcontroller breakout board coming out. At $4 it's nearly as cheap as a Nano, better build quality than an eBay blue pill. https://www.raspberrypi.org/products/r

I am looking for a JackAl board at any stage of build or completion. If you have the board/parts and are no longer interested in completing the project, I am interested in whatever you have. Please co

Ubitx v 6.1 with WSJT-X set to FT817 The serial IO parameters are correct and match the settings in the device manager CH340 The error is "Hamlib error: Target VFO unaccessible" or "IO error while get

I have a new ubitx ver 6.1 When I try to use WSJT-X I get the error "ham lib error: IO error while getting current frequency" and the Raduino reboot The serial port settings are correct. I have tried

All: I have lowered the price of my Beginning C for Microcontrollers book on Amazon (search: B08GFDGN7P). Also, the small font size issue has been corrected and the book no longer tosses in a few blan

This past weekend, I went back in time and reviewd posts back to 2018. About half way through I started taking notes but... I did not take any notes on how to unbalance the balanced modular to get a s

A question of curiosity about FT8 and the level of power being used, I have a uBITX v6.2 with a usb dongle running approx.5-7 watts into either a cobweb, 20m hexbeam, or a 20m delta loop, all antennas

gector, The answer to your question regarding how they handle memory access race conditions on the dual-core chip, is: they do NOT. Memory arbitration for multiprocessor "atomic access" remains the re

Opps...pressed the wrong key! The Arduino flavor will have 16Mb of flash, according to: Welcome Raspberry Pi to the world of microcontrollers Welcome Raspberry Pi to the world of microcontrollers ‘Ras

Hi all, Have anyone adapted the raduino board layout and arduino firmware for a SI5351C instead of the SI5351A (just set CLKIN to 10Mhz for my GPSDO and set the freq ref of the pins to the ubitx to us

I just spent several several days to get the best possible calibration using an oscilloscope, my Ears and Ashhar's audio spectrum analyzer. The radio has been modified with KD8CEC firmware with 3.2 Ne
