Hello! My ubitx v3 doesn’t drive power at all. I have meassured all tx check points and values and they are all fine except finals. I have changed them but same results. Any Idea? I followee this guid

All: Al and I are looking for a company that can do a prototype PCB production run (e.g., less than 5 boards) at a reasonable cost (under $5/board) and have the boards in our hands a week to 10 days.

I have a ubitx 6.1 that I was attempting to correct then lagging first CW character, and use a straight key with. I followed KD8CEC directions, and can get as far as x loader. The com port is correct,

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

As a non-EE, non-technician I have to agree with Jerry, and worry that the characterizing of some of the inexpensive test gear as manifestly inferior or useless might discourage people from buying, tr

Hi there, Just build the new EasyBitx 20 kit from Amateurradiokits. RX is excellent, AGC works very fine. Transmitt Output Power is 3,5 Watts. Still there is a problem. When I apply modulation to the

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 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

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

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

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 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

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
