Hello to One and All .... looking for some help on this v4.3 of mine . The radio receives perfectly and I upgraded the Firmware to KD8CEC's version for this model . If I plug in a Key & go to send not

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

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

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

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

All: There's been some discussion about antenna tuners lately, and I wanted to show you Al's (AC8GY) latest refinement to the Projects antenna tuner. Everything is much the same as presented in the bo

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

I have an unassembled Bitx20 Version 3 for sale for $65 plus shipping. Both exciter and linear boards are completed. Includes case and all parts (digital display-fan-knobs-meter-connectors-hardware) n

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

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

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
