Fascinating... More soon...

Curt, Your AGC can be add in option, but on Ubitx site where is no schématic. I think that the LDR and LED can be replaced with opto transistor like that. it insulates from the ambient light On the PC

D7 right (TX_RX)? found.

Loris, The Nano Every is something that I want to try. It should give me 16k or so of extra program space. I tried compiling my sketch with the board setup for the Nano Every and only ran into a coupl

P.S. I have read that the DAY-KIT linear amplifiers made in China use a positive PTT (> 5Vcc for the TX state) ... if you set the PTT of these linear amplifiers to GND in TX, the linear remains in RX,

Hi Mark, I read that you intend to use an ARDUINO NANO EVERY to do the tests, I notice you that: the EVERY despite having a hardware pin to pin compatible with the OLD NANO, the microprocessor used is

Gerard Your ubitx may be one of the hottest around the planet. Most here would vote you a French ham license if you don't have it yet. Okay you didn't include my favorite led and photoresistor agc, bu

Hi all, In order to do the rx/tx switch in a PA, I need a control signal for it. The most obvious is the PTT one, but as I'll be keying the radio over CAT, I think it is not a possibility, right?. Fro

I forgot to mention that I am inspired by this project see here AMP Lab at Virginia Tech - uBitx Workshop (google.com) it is necessary to give back to Cesar what belongs to Cesar lol Made with Kicad,

Hello, This is my creation. I’ve spent a lot of nights on this project. it’s a bit like an auto show A prototype that will be built with only one copy. I let you discover... Extended 12v and 5v power

Diego, Before you do anything, be sure that you do have an antenna connected as Dave questioned. Here is a link to calibrate the Frequency and the BFO as suggested by the lead designer, Ashhar Farhan:

Diego Possibly the problem is the bfo needs to he aligned, it may be way off. The bfo is a fixed frequency oscillator that mixes the IF to audio. If it is adjusted way off, nothing is heard in the aud

Mark, Thank you for confirming. I decided to keep it as-is because they are cheap and I should have spares available. 73, Paul.

I found this link that describes the operation of J1. Run Arduino Demo in spi model - LCD wiki Basically, both Ashhar's and Ismo's answers are correct. The link states: The short-circuit method has th

The board I have looks identical to the one in the uBITX v6. The only thing missing is the QC passed sticker. I see on the uBITX board that J1 has a drop of solder across it. Thanks, 73, Mark, N8ME

The jumper that needs to be bridged is marked 'J1' I think this bridges the input pin to the output pin of the '662K' device on the underside of the LCD. The input pin is connected to the Vcc pin. I t

1. Many of the ILI9341 boards that i got needed a jumper to be installed to get them going. Do confirm that the board you have is with the SPI interface. Check the ubitx diagram for compatibility. 2.

I would like to include some screen shots of my uBITX v6 display in a presentation. Taking pictures with a camera is tedious and doesn't give the best results. Is there some inexpensive software that

Ismo, Thanks.

1. No, you need level shifting. This can be a simple resistive divider om the input signals to the tft. Or one of the cheap active level shifter modules. 2. I think you can power the display from the
