I suggest any critical calibration values be saved along with the serial number
Put data for all rigs in one ascii text file on the hfsignals website, available to the public.
This could easily be automated as part of the calibration procedure.
Could also print the calibration data on paper and glue it to the bottom of the PC board
for those that don't always have reliable internet access.
In addition, I'm all for?including an RF detector and appropriate attenuators on the board
so users can easily characterize any filters and do other troubleshooting of the rig.

It could be improper connection at the speaker jacks internals.

Dear all,
Much appreciate responses. I believe I did the assembly properly. For now, I will:
1. Try listening for noise with headphone jack
2. Re-look at the assembly as pointed by Evan?
and Hope this is solved. Will post update on this once I do. Thanks again for patient responses.
regards,

Prashanth,
Sorry to read that your v6 is not working.? Sometimes it is the simple things that get us.? Are you sure you connected the speaker and encoder to the correct connectors?? Spare connectors on the mainboard are identical to the correct ones.? The two that come to mind are the alternate antenna connection and the Audio connector.? The speaker can be connected to the antenna, and the encoder can be connected to the audio.? Both would cause the radio to malfunction.??
I would suggest you review the assembly instructions here:
Look at the picture in Step 8.? Note the Encoder connection to the Raduino board behind the display and the speaker connection in the upper right (the brown and black wires).

Farhan,
Rather than lock the Calibration and BFO settings, I recommend that the current values be displayed when starting the adjustment.? That would allow the Ham to record the factory value and return to it if needed.
Most of the mods add this feature as well as the other options.? Some even allow us to save the values to a PC file.
It is an excellent radio for the price.? I have 6 of them from my first v4 to my current v6.? I did modify all of them.? Being open-sourced is the beauty of these rigs.? It makes it easy to add features or change the operation to suit the individual Ham.

While I agree that often the problem is that people start adjusting things that are not broken, the ability to do those things is one of the positive features about these rigs. The caution really should be to not make ANY change until the rig is tested as supplied from the factory, including adjusting the calibration, VFO, changing the software, or installing a new display.
In this case I am understanding that the radio has no audio output at all, without any adjustments.

Make sure the connectors are in the right places, like for the speaker. Can you hear anything if you plug an earphone into the jack?

Maybe I misunderstood something but my V6 did not work correctly until I reset the BFO. This was a year ago. ?The instructions were adequate for a 77 year old ham to figure it out without too much pain. ?Also, has to make a mod to get it to work with CW. ?I am still using the original firmware. ?I used a KiWiSDR 70 miles away to listen to myself as I changed things ever so slightly. Now I have a neat radio to play with for $206.00 from India. ?
It might be helpful to lock the BFO settings. ?It might have been something else but adjusting the BFO fixed it for me.
If it ain¡¯t broke break it so I can fix it¡..Ha!

All:
First, I posted this to multiple sites to tell you NOT to buy something. Let me explain.
Al and I have been discussing our book and have planned changes for it to the extent that we are going to do a revised edition, not one that just corrects typos and the like. The normal procedure followed by publishers is to put the revised edition of the shelves first and then tell everyone about it. That way sales don't dry up before the revised edition comes out. That's not right, especially with the Holidays coming up. If you were planning on giving the T41 book as a gift, take a 5x3 card and write on it that, if they still want the book when the new edition comes out (March 1st, we hope),? they will get the revised edition of the book.
We have both learned a lot in the months since the book first came out. We want to pass that new and more in-depth information on to the reader. I am taking a fresh look at the software from the perspective of not only telling what a certain piece of code does, but will try to point out how you can modify the code for reuse. There are lots of functions that might be useful in other applications, too. There are software/hardware blends that will be covered, too.
We're always asked: "Should I buy a new copy of the book?" I almost always say "No" on revised or new editions. Most new editions have only minor changes to the subject material. While we do expect to plow new ground in the revised edition, If you already have a copy, stick with that for now. See what the reviews says after the new book has been out for a while.
So, if you're thinking about buying the book, hold off for now. We think it will be worth the wait.

I just install a RTC clock on the SBITX falowing the PA Ugrade kit instructions at the clock I2C. The question is, there is a SBITX software upgrade for the RTC to operate properlly? Is so where I can dowload it? By the way I already install

I have fully assembled/tested SBITX with PI-4, screen, and microphone. Serial number 38.
Receiver works great and have never transmitted.
Since I am a software person I shy away from many hardware projects.? I offer for sale
at what I paid $499 shipped in the USA.? I will also include the update kit when it arrives.
Reach me direct at w2ctx @ yahoo.com

Re: #sbitx upgrade kit 2 is on the way
#sBitx
Looking forward to the update. Things were going to fast for met to keep up with and I'm still working on the uBITX V5 LOL.?
