My new sbitx case
Finished my sbitx case today.? The screen is a 10.4" 1600x720 WIDE display.? I went without encoders.? I still need to add some vents, but without them, my PI runs about 54 degrees C.

It would be really NICE to have it added to the sBitx.... Gordon KX4Z [email protected]> wrote:

Re: NBFM (Was: AM on sBITX?)
Rafael, How to add it to sbitx software. Did not explain myself right. I have a 2m radio using the sbitx software. That is why I asked about the fm mode. Juan WP3DN

Re: NBFM (Was: AM on sBITX?)
Most of SDR software already has NBFM. Do you want to implement it yourself? - Rafael

Re: NBFM (Was: AM on sBITX?)
I was considering taking this on a month or so back, But I have not yet had the time to commit to the project due to other responsibilities.

Rafael, But how to add the mode is the question. Juan WP3DN

Re: NBFM (Was: AM on sBITX?)
But why are you not using NBFM with sBitx? Its bandwidth is by far much wider than what is needed for NBFM. - Rafael PU2UIT

Re: Looking for flow diagram of the audio paths for sBitx v2 or v3
Sidetone is not used. The module of the loopback or the wm8731? It is basically read and write to the device, there is no mux in the driver. If you want we can make a call I can explain what I did,

Re: NBFM (Was: AM on sBITX?)
Rafael, I also have a 2m working system. If you would like to test any implementation of nbfm or any other mode let me know. Juan WP3DN

Re: FT8 sBitx v3 v4.01 Power Output
Kevin, pull the JS8Call "Power Slider" down to around -28dB to start with, about a quarter way up from the bottom.? At max on the power slider you will over drive the system. I run my naitve sbitx

Re: FT8 sBitx v3 v4.01 Power Output
It’s even more sloped than a pure percentage. 50% percent means 50% of the voltage, not the power. The power will be 1/2×1/2 of peak or 1/4 of peak. When you’re at 25% you will have 1/16 of the

Re: NBFM (Was: AM on sBITX?)
Not yet... I'd love to see NBFM on this platform so I can effectively use my transverter for other modes.

Re: Looking for flow diagram of the audio paths for sBitx v2 or v3
Thanks for replying. It seems complicated to many of us especially when tiering 3rd party applications. There is some trickery going on in software that controls the Wolfson module loaded into Linux.

Re: Looking for flow diagram of the audio paths for sBitx v2 or v3
Hi JJ, I wrote the software we use from scratch, so I understand it very well, and it is not complicated, indeed, I can not imagine something simpler than the sbitx. What are exactly your

Re: Looking for flow diagram of the audio paths for sBitx v2 or v3
Forgot to mention is that the main reason for understanding this current architecture is to convert it over to pipwire. I need to understand how and what it's doing before making changes.

Looking for flow diagram of the audio paths for sBitx v2 or v3
I am trying to figure out the unnecessarily, complicated audio plumbing for the sBitx v2 and v3. Has found or attempted to reverse engineer this?

Re: FT8 sBitx v3 v4.01 Power Output
Oh snap, you're right.? The units for that field must be percentage and not watts like I was thinking.? I cranked it to '50' and it does show much higher on the power meter and the sbitx app now

Re: WM8731 alternative?
If somebody has purchased good ones at Aliexpress it would be nice having their coordinates, I also rolled my own and, I'll start functional tests, at least the 12 Mhz works. 73s Hubert F6DUK

In the circuitry. Look at the resistoe capacitors around the T/R circuitry of 2N7000s. [email protected]> wrote:
