Hi.

I testet TX today for the first time on my #sbitx_v2 and I can't get a decent modulation on USB/LSB on any band. I tried all kinds of combination of mic / comp settings and the modulated signal is always very weak, distorted and crushed. It sounds like a bit crusher effect and is not usable. With mic settings above 50 I get some kind of digital background noise feedback.

Has anyone else experienced this kind of behaviour and has a solution for it??

Hi,
It has only been a small experiment and I don't know if it's worth putting a lot of effort into it because I know that Ashhar is working on a new version of the software and these changes would be lost.
Perhaps the new version could incorporate some configurable schemes to adapt the screen to each person's specialized uses: CW, voice or digital modes.

Gordon: I'm going on a trip today but I promise to put the risers backwards.

Thanks for the tips and suggestions Evan and Rafael. Oddly enough, I thought that this particular panel didn't use the DSI connector for the touchscreen because it only functioned properly when connected through the pogo pins. However, it turned out I had a bad wire.

Looks like the 10.1" panel is similarly wired to the official one and works in the same way, with the FPC cable for both video and touch, and a set of wires for power.

Unfortunately, I've also only been able to get the 64 bit version of the drivers working on a fresh install and couldn't get the display working with the original provided SD card, so I'm building it fresh. I ended up not using the pi username without realizing the installer assumes 'pi' in some cases such as making directories in the pi home folder.

Any chance there's a way to configure this differently without much issue or is this assumption made in too many places to change easily and I should just reinstall and be stuck with the default username of pi instead?

I really like the way you have grouped power control items together and other choices. ?

Fascinating!?

OK, my goal has been to document the performance as I received it secondhand from the gentleman who bought it and said he never transmitted with it. ? So I think now I have a good list of where filters need a little tweaking.?

With my limited available time I think next I’m going to pull the main board off, add zeners on the gates, and switch out the insulators for aluminum nitride if I can find my extras! ?

i’ve looked a little bit into the seven pole filters and it looks like I could tweak with some added capacitance at especially beginning and end, and possibly bring 20 m and 15 m closer, ?or into compliance. ?If I lose power at ?18MHZ or 28 MHZ I’ll have to make some trade-offs. ?It is possible I could connect a BNC (after disconnecting the output transformer) to the input of the filter section and map the filters as they are. ?It’s always possible that there has been some damage that I don’t know about, rendering the filters not as effective as others ? ? It was very clear with the filter added to the output that this can be cleaned up to just beautiful!!

I have limited limited time because I’m teaching high school students but I’m going to try to get a little bit done. ?

An interesting modification.

Hi Owen,
I've done a little experiment to resize and reposition some elements and buttons.
Modifications can be made without coding, just by changing the positions and sizes of the elements in the definition of the field main_controls[] structure (approximately in line 443 of the sbitx_gtk.c file)
Saludos,

Hi,
At the moment, I have commented the lines and the access works correctly from the internet, using NAT. I don't know if commenting on these lines may have other unwanted effects.

Hi, I wondered if the main screen layout could be altered to a more SDR larger screen, It seems a waste of a 7 inch screen. Although I have the sbitx V2 and it's great, I think there's too much wasted space on items that could be made smaller, and give the priority to the radio SDR interface, and make that larger? Maybe have buttons to switch screens etc, or have the option to change things etc. Owen G0RCL.

Thanks Ashhar, I will continue investigating.

Hi,
I am trying to access sBitx V2 from the internet and I am not able to.
Actually, I can access the page http://elconucosbitx.zapto.org:8080, but after entering the password, the initial page appears again (this time without the virtual keyboard)

Any idea of ??the problem?
Thanks,

Dave,
When I started this process, I loaded the OEM firmware on the new Nano (actually two of them). I also copied the eeprom data from the original OEM Nano to the new ones. In both cases, the BFO cal couldn't be accomplished.

Then I loaded CEC firmware on the two new Nanos, but BFO cal. was not possible. Today, I tried 2 variations of CEC firmware (NX and NX_S), in case one was corrupted. Same result.

As noted in previous posts, with the new CEC Nanos, the clock signal bandwidth looks abnormally wide. With the original OEM Nano, the clock signals are narrow. So... maybe I have two bad Nanos (although Mark H. told me he has never seen a bad one).

I loaded CEC firmware (NX only) on the original Nano. The clock signals have broad bandwidth. BFO cal doesn't work.
I loaded OEM firmware back onto the original Nano. The clock signals have broad bandwidth. BFO cal doesn't work.
(Note: The OEM firmware was loaded with Arduino IDE. I did not edit anything, assuming that the default settings are right for the original configuration.)

So, I guess it's time to swap boards with Mark and see what happens.

Dave,
According to Ashhar's video, with the OEM firmware, the calibration settings are saved by pushing the tuning knob in, and turning radio off/on. I missed the need to turn off/on, which must be done between steps (i.e., step 1: calibrate BFO, step 2: calibrate Freq., step 3: calibrate BFO again).

With the CEC firmware, the instructions in the "yellow box" say to "PTT to confirm".

Mark's offer to swap boards is very kind. I expressed my appreciation to him by private email. He offered a few other suggestions, including a way to read the OEM eeprom via avrdudess. So I will check into that.

Also, because the clock signals look clean with the OEM firmware on the OEM Nano, but are very broad with the CEC firmware on a new Nano, it seems to me that the fault may be with the new Nano (damaged somehow, or corruption of firmware). Therefore, I'll pursue that angle, before trying another Raduino.

I really appreciate all of the support and suggestions which have been offered. The Nextion CEC mod looks very promising. It also seems simple to perform (until a guy runs into a glitch).

SaMa,

I would install the snap-on ferrites on each cable, including the one that connects power to 220.? You could also try on the power for the PC and the power for the BiTx40.

You can try adding one at a time to see which ones help reduce the QRM.
