Yes, the TX rail has 12v on it whenever the rig is transmitting, 0v when it is not. Probably your best choice, and easy to tack a wire on it. Does your amplifier really want a 12v signal, or something

Upgrade the regulator to feed the screen needs.

Aaron, I have not used a 5" screen. I have used a 2.4", 2.8", 3.2", and a 3.5" Nextion. They have all worked the same to the most extent, though some of the Nextion programs have more features than

Most switching supplies respond well to having a 0.1 mfd and a 4000 mfd capacitors across the output, right at the power supply end of the cable. It is difficult to get noise through that

I'm wanting to upgrade to a larger Nextion and I came across this 5" one. 5.0" Nextion NX8048T050 TFT HMI USART Intelligent Touch Display LCD Module 16M 5" Nextion Display Would it work with the

Hi, I'm looking to add a PTT-OUT to the back panel of my uBITX, to control e.g. an amplifier or a switch to isolate an external SDR during transmit. My thought is to grab C154/D11 or one of the other

I don't personally have one, but people who put these inexpensive switching power supplies on oscilloscopes to look at their output often recommend the Mean Well brand, which is almost twice as

I've had no problems with RF noise from this supply: https://www.amazon.com/dp/B01EWG6YT8/ — BMOUO 12V 30A DC Universal Regulated Switching Power Supply 360W I did install ferrite chokes on the AC

Eli, Have you tried the "Fake It" setting in the WSJT-X setup? It adjusts the radio frequency to allow for a wider passband. An example would be moving the received (and transmit) frequency to allow

Eli, I have a a Signalink USB & I just came across this video on YouTube: https://youtu.be/dXha5UynvkE. Do you think if I made this cable for my Signalink interface & used a usb cable from the PC to

Robert, This is how I set up for FT8. I haven't tried much else. All of this is on a windows PC...although I have a rasperry Pi I may switch to. I am doing the following: 1. Installed WSJT-X-

While we are on the subject of USB cables, be careful of those meant only for charging. Many USB cables these days save $0.05 worth of copper wire by not including the data wires, just power and

Nice set up. How did you connect the ATU antenna feeds to the uBITx?

Jerry and Arv, Thank you for the corrections. I did get the mini and micro mixed up. I guess the best bet is to wait for the Nano to be delivered and then match the connector on the

Jerry I have older Nano boards that have the Mini-USB connector, but the latest purchases all have the Micro-USB connector. While this does make the Arduino use same cables as cell phones, it also

Good info. A minor correction: The Nano has a USB-Mini connector, not the USB-Micro that you find on most Android phones. Jerry, KE7ER

Thanks Evan - will do the checks!

Rafael, The code you provided looks correct, and the TXA output should be off when one of the lower bands is selected. Can you verify that the TXA signal on the R151 / C153 junction is close to zero

Hi Evan, Thanks! It is the v6.  I changed the firmware - I double checked the code I'm using, and " digitalWrite(PIN_TX_LPF_A, 0);" is there in the lower

Rafael, The answer depends on your mainboard version. For a v6 board, the answer is no. Have you changed the firmware in the Nano replacing the stock firmware? We will need a little more detail to
