Got it built, but need some audio tweaking.

Alex Netherton
 

I finally got the thing built, a V5, and with some trepidation, powered it up, fully expecting to see smoke coming out the cabinet. Oddly, I got sound out the speaker, albeit "tinny".  (I was a bit surprised that there was no backlight on the panel, but I do not see why there would be, but a flashlight fixed this.)

Though I could tune in on a signal, I could not zero in on a SSB signal, as it sounded like a toy. The speaker was a Nagoya I got for my mobile FT-7100M, which worked fine for that, but not for this. I think it is 8 ohm, possible 4 ohms.
I went and dug up my MFJ headset, and put it on, and the sound was a little better - was able to copy WWV code bulletin on 40. (Well, I was able to hear it - copying 18 WPM is quite another matter.) I did discover that the passband is likely for SSB, as I was hearing several stations at once, sort of like one of my old Swan rigs with no CW filter. (As a Novice, I got good at using my brain as a filter, as I did not have a rig with a CW filter until around 2014.)

Is there an impedance I should be looking for in speakers? The Nagoya is 8 ohm, as are most external speakers, or do I need an amplified speaker, or a certain type of headphone?

Please understand, I did not expect earthshaking results from an absolutely rock bottom affordable kit, and know I will have to "tweak" a bit before it works right.

Thanks everyone! 73 es gud dx!

Thanks for the info.  It would seem that if we want to make very high resolution images available to group members we may need to store them on G-drive or something similar and publish the URL for the image location.

Groups has a limit of 10 GB of storage for "Premium" groups (at $220/year).  I suspect resizing was set to help keep us under that limit.  Not unreasonable.  Looks like we are at about 3 GB now of just photos, files, and attachments.

Re: ubitx #v6 Screen Speed Mod #v6

 

Reed,

Well I felt adventurous for a moment but not anymore. It completely broke the the radio, I had to load your original code back on. It was off in la la land, i couldn't tune any frequencies and the BFO was way off. When I tried to calibrate everything locked up with 0's in the frequency display. I'm back now and making QSO's again.

Arv,

That's not necessary, as they can simply be zipped and saved in the files section, like I already did, so we can keep all the information in one place.

Niel,

From the schematic, the headphone jack is wired for stereo headphones.  Using a mono plug will short out the audio, so make sure you are using stereo headphones or a mono to stereo plug adapter.

Did you get the speaker wired up and plugged in OK?

  Jim, my LG Zone4 is always auto correcting to what I did not type or want, makes for extra editing.

Re: UBITX6 arrived today - cracked display

I hate autocorrect.  Should have been "bought the full kit" and "If you have the basic kit" instead of what my email program wanted me to say - LOL!.

To reiterate though, as long as it has that 14 pin single row connector, and it's an ILI9341 display, it will work just fine (assuming J1/JP1 is shorted).

Paul, 
You can.  Make sure it's a 2.8" display or it won't fit the mounting holes or the window area if you bout the full kit.  If you have the basic key and are building your own case, you can even use a 3.2" ILI9341 display with the same 14 pin connector that the factory uBITX supplies BUT, I repeate BUT, the mounting holes won't line up so it wouldn't fit a factory case.  That 3.2" ILI9341 display has exactly the same number of pixels and uses the exact controller as the 2.8" display so absolutely NO software change is necessary to use the larger one.

When you get the replacement display, check the back.  There is a solder blob jumper called J1 or JP1 that is left open on some of those displays.  In order to work with the V6 uBITX Raduino, this jumper must be soldered across.  That puts the display's 3.3V regulator in circuit.  The display doesn't like to work on the V6 Raduino if you don't have this jumper shorted.

All this information is from actual experience here with a V6 Raduino AND the two displays.

Hi Group!

My UBITX6 arrived today - I am looking forward to building it!.
The glass of the display seems to be cracked in the corner.
Can I replace it with any ILI9341 320x240 display from ebay etc?

Thanks,

If you start the rig normally, you can hold the button for around 7 seconds (feels like forever) and it will show you the settings options menu. I think a settings menu button would be a good addition to the UI so people can more easily discover it.

You can try it out and chances are good that it will work until you get a replacement. As to replacement, just make sure it has the same pin configuration and it should work.

My issues resolved.  

(1) Cycling to TX was a faulty mic jack on the board.  
(2) USB/LSB incorrect was fixed by doing the alignment of Freq and BFO.  Works properly now.

Thanks for the reply.  I had not seen that post.  Unfortunately, I don't see where it gets to that level of detail.  It may have been there at one time.  Many of the pics are no longer displaying.  

Re: ubitx #v6 Screen Speed Mod #v6

Just pushed some updates to the pdq_gfx_update branch to fix the settings menus (and save another 210 bytes = 10% RAM). Based on Ashhar's comments at https://groups.io/g/BITX20/topic/fonts_used_on_reed_s_code/69414198, I might have to change a few things before it's merged into the main line.

If you're feeling adventurous, I have a new branch at https://github.com/reedbn/ubitxv6/tree/one_stop_settings that includes all of the pdq_gfx_update branch updates, but also has a significant refactor of how settings are handled, in addition to a few more tweaks. It might fix the LSB/USB issue you saw earlier, Joel. HOWEVER, I must reiterate that I haven't finished building my radio, so this branch currently has absolutely NO testing on a full-up radio. There may be issues, and if you run into them, please let me know.

Re: Fonts used on Reed's code

Reed N
 

Hi Ashhar,

1. I switched the font because the program memory was pushing the limit (as I was making changes I ran out of program space a few times), and the new font is about 30% smaller in flash size. There is no aesthetic reasoning behind the change, and I'm totally fine if you want to switch it back. https://groups.io/g/BITX20/message/74411
2. The PDQ library renders stuff slightly differently than the library that was being used before, so none of the previously coded screen offsets worked, and I had to change a BUNCH of alignment stuff to get it to look the same as you originally had it. I believe that the issue I ran into was that the letter spacing offsets didn't work quite right, and rendering the whole thing each time was the fastest way to eliminate that issue (at the cost of refreshing the whole string).

Per https://groups.io/g/BITX20/message/74411, I discovered that there's still a rendering issue in some of the setup menus, so I'll update my PR tonight with those fixes. If you want me to change the things mentioned in 1. or 2. back to the way they were in this PR, I can do that too.

Re: Version 6 Arduino

Well I am getting closer. I have tried to get the new sketch loaded using a Mac, Ubuntu desktop and raspberry pi. Each attempt fails. The latest attempt on the raspberry pi did compile but it failed on upload.  I have a problem getting it to see the correct port. I am now going to try this on a windows machine. The last time I had to do this, it was not this difficult. I guess I have lost my touch

Fonts used on Reed's code

Ashhar Farhan
 

Reed,

Two questions,

1. I notice that the font you have used is different from the one in my repo. Is there a reason for that?
2. The frequency update in the original code painted only those digits that changed. why is that removed?

The code is really fast and good!
