Hi Raj, Yes, the C4 goes to RF Tag, the wire from Pin 4 (U3) seems to be a remnant of some link unless it is meant to go to a specific location? Looking a bit further, The Antenna route goes from the

Hi Ashhar, Thanks for the clarification. ?I didn’t think the demo was from the wjstx code. ?I assumed it was “native” code. I will look forward to native sbitx JS8Call functionality but I am

The circuit is a direct plot from the production circuit layout. Charu, can you tell me where exactly is the problem? - f

And they don't ship the Pis, so for those of us in FL, a trek to Atlanta just not worth it.

C4 goes to RF Tag.

Hi Farhan, Studying your circuit I have stumbled upon a query, how the antenna connected to your RF tag in the schematic. Is there anything missing in this section ? regards charudatt – VU2UPX

Congrats Neils, Mine is 0009 After personal coaching from Farhan I found a cheap logitec wireless keyb+mouse a delight to use. I was able to upgrade after a git pull with instruction from the manual.

Farhan: Think about it. In my mind, the smartest thing Ritchie did was to develop a language with no inherent I/O. He pushed all of that stuff into the standard I/O libraries, leaving the language

Thanks. Just a thought since I have a pi400 and the astronomical price of the pi4. Barry

I agree that it's a good idea to isolate hardware support code into a Hardware Abstraction Layer - HAL. JAMES

We looked at that option. It is prone to many problems because the gpio needs to be really close to the codec. With the RP400, we will have to use a cable that will create ground loops. While the

Using a Pi 400 would lose the self-contained aspect, and might present some shielding challenges since it would be outside the box. But it's the same processor with the same ports aside from one USB

This is the LM380 picking up the wifi. It is a low rumble like bubbles escaping and then it is gone. I think adding a snubber should fix it. Lemme try that later today.

Would it be possible to run the sBitx on a PI400 with a mouse? Sent from Mail for Windows Sent: Monday, August 1, 2022 7:59 PM To: [email protected] Subject: Re: [BITX20] sBitx running FT8 My proposal

John, Thank you so much for your encouragement. The bitx series is a community effort and fully open source. The contributors are many and I have acknowledged some in my paper. The sbitx hardware is

Ashhar, that would sound reasonable and logical to me.

My proposal is that we isolate all the wiring pi stuff (mostly flipping gpio pins and reading them) to a file called hw.c where we can port the sbitx to other platforms and write the required routines

Hello Ashhar, I have been following your developments for a few years and am very impressed with your products. I just purchased the uBitx kit and looking forward to building it. Most of my operating

I also stopped using Wiring Pi in favor of the extensive pigpio library for C/C++ and Python. -- 73 Bob? KD8CGH

From time to time Microcenter has Pi 4s at list price. They were available locally and I picked a 4 GB one up on the 26th, just before the sBitx became available. They had "25+" in stock and none the
