CW Audio High Pitched and Thin #cw

Dean Souleles
 

I have a question about CW audio.  I have V5 ubitx with a Nextion display running the CEC firmware.  When I switch to CWL or CWU the received audio is quite thin and wispy and the pitch is quite high compared to listening to the same transmission in LSB.  There also seems to be additional noise in CWL or CWU.  This all is different from what happens on my other rig (Kenwood TS-450S).  

I'm not really a CW user (yet) but have been experimenting while I am learning code and am not 100% sure what to expect.  

Any thoughts would be appreciated.

73,

try this with zoom feature in gfx editor such as GIMP Upscaled it 300 % in size so enough resolution to read connector labels easily

Wow, Groups severely degrades the resolution when I save it to the pictures section.  And it won't let me put a photo in the files section.  So I've zipped it and put it in the files anyway.

Re: V6 WIRE UP

 

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?

Re: V6 WIRE UP

 

Yes,

I just uploaded a 1.3 MB 2448 x 3264 pixel jpeg photo from my iPhone and it reduced it to 195 kB 768 x 1024 pixel size.

768 x 1024 is not that bad, but it would be nicer if they made a file size limit rather than a pixel size one.  Often you can reduce the jpeg quality a lot and still have a clear enough picture, and having a larger pixel count can help a lot on viewing details.  Reduced jpeg quality mostly just results in blotchiness in blocks of colors so it's OK this type of work.

Neil, do you mean connector plugs with wires and not jumpers?  It seems that the extra connectors are not needed and are provided for experimenters.  Do you get any sound at all (e.g. hiss etc) or is the radio completely silent?

73,


Mark.

Re: [OT] Image resizing

Bill
 

It's built into Groups admin settings in the Features -> Photos section.  The setting is called "Max Size in Photos".  The default is no resizing.  I suspect it is set to something smaller.

https://groups.io/g/GroupManagersForum/wiki/Managing-Attachments%2C-Files-and-Photos

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.

TYes that does help.
Now can you tell me where the jumper wires that the group is talking about goes?
My unit still does not receive and I still have two 2 pin jumpers and a3 pin jumper.

Neil k8it,

In words, the mic/ptt jack is the one left-most, closest to the volume knob. The headphones jack is in the middle. The keyer input is on the right.

The internal speaker plug goes to the 2-pin header right next to the volume knob.

The raduino plugs into the long header behind the mic/ptt and headphone jack.

Does that help?

Regarding the extra wired connectors, they are extra for experimentation:

Re: ubitx #v6 Screen Speed Mod #v6

Hi Bert,

I did shrink the font. I may be able to scale it back up at some point, but those characters take a LOT of room, so I dropped to a smaller size for now, with the definite intention that it should be revisited. Ideally we'd use some font strategy that used large characters with very little glyph details to save on space, but I figured fast and a little smaller to start was better than running into the memory limit sooner.

Glad you're enjoying the speedy updates. I didn't intentionally change the step size in this branch, so I suspect the improved dial tuning is purely due to less time spent drawing the screen - a free bonus!

All,
I did discover that there are a few menu options that I forgot to fix in the current version. They render enough to be functional, but they're not pretty. I'll jump back to that after I've gotten the settings changes branch in a good place.

Reed -- Your mod is much faster.  Also noticed that the tuning steps are smaller than the original, which is more pleasant to the ear.  But, the frequency numbers are smaller and harder to read.  I would like to see a larger font for the frequency display.

Very nice improvement!  Thanks!
