Just nasty noise...Not the keyboard..Abox mini one..pulled that out..
you can see decode is fine, but no audio.
when transmitting tones, but doesn't key transmitter. and most of the time once it does transmit, never switches the Rx back in.
ugg.
front end is very cool!

sBITX question

 

newbie question..
when trying to do git pull to grab the new updates, I get a prompt about? your local changes to the following files would be overwritten by merge:
data/user_settings.ini
Please commit your changes or stash them before you merge.
Aborting..
so?i copied those to the desktop.
tried running it again
so did it pull the github update? and then i just build it ??did it actually grab the update,??

In our neck of the words, if a radio is important to us we build a polarity protector that connects directly to it. ?No battery or anything is allowed to connect direct again, must go through our polarity protector

This is until some 'clever' guy will try to use his own wrongly wired cable. So the protection in the box itself will make better sense.
Now in this 'prerelease' period dangers are perhaps low, but as less routined hams will come that will change, I'm afraid ...

Bahrain has a good video about loading software on the V6 on YouTube. ?Main thing is getting it in the right subfolder and with the right folder name.
There are a couple of versions of the software. ?The ones I have include a couple of fixes for CW speed readout, etc. ?The one I'm using is named, at least on my computer, as uBITX_6_HI_VIZ. ?Email me if you can't find it.

Re: uBITX V6

 

yes, me also Howard.. just about to load n8me software

Do I just load the ino file to the? raduino, compile it and then upload to uBITX (V6) ??

Also going to try the sota dsp kit module, interested to
?see how you get on..

Barry,

The values presented by me is for everyone building and not a solution to your issue but

it may improve it.

Please look for component issues, if pop corn noise if present is a component failure.

The original on LTSpice turned up with a 10KHz roll off which is too high. So

changed values with suggestions from Farhan till it looked right at 3-4KHz.

This should reduce high freq whines and hiss.

For better results change the following values and try:

R27, 28, 31, 32, 35 & 36 to 2.2K

C32, 33 & 37 to 0.047u or 0.05u

Re: Daylight again radio audio filter

 

Correction Raj,
I found them in a post that I missed.?? Thanks for the new values.

Re: Daylight again radio audio filter

 

Dear Raj,
Can you share the values of the components you changed so the rest of us can update our Audio Filters?
I am working with a group of newbie builders and we want to incorporate the changes as we build.?? Maybe
they got published somewhere and I missed them.?
Thanks for your changes.
take care and have fun.

Re: uBITX V6

 

Greetings
I really like the N9ME software for CW. ?Usability is greatly enhanced by adding a filter. ?I've put the Hi-Per-Mite in mine.
My CW upgrades are described here


I recently acquired a second V6 and am going try installing a Sotabeams DSP in this one. ?It will be interesting to compare the results.

Re: Ubitx version 3 heatsink

 

Every radio I have ever looked at used one heatsink for the amp. The 50 watt FET amp that won the QST challenge did too. I¡¯m not planning on pulling the fets off the board and mounting it far remote. ?I think it will work but wondered if any problems came up. I didn¡¯t find any heatsinks suitable at the hamfest yesterday anyway. I was thinking of making a tiny Manhattan board and mounting it flush against ?the main pcb to mount the IRF 510s on for easy replacement. Sort of a trace extension. Tack the 510s to it so they are easy to change and repeat soldering won¡¯t lift the traces on the main board. A board just big enough for three narrow lands with a piece of bare wire maybe 1/8¡± long to connect to the main board and have it butted against it to keep it as short as possible. It might work and it would help keep the repeated soldering heat off the main pcb. The heatsink would have other physical support. I might try two using old cpu heatsinks since they are easy and probably have some around. It doesn¡¯t have to be one big one. Just an idea.

Re: #v6 Day 3 #v6

 

Thanks, fellows. ?I'm probably going to set aside the Nextion for now as I'm very happy with the N8ME sketch for CW. ?Maybe later this fall or winter I'll try the Nextion again.

Re: #v6 Day 3 #v6

 

Hi Howard,
Sorry for the delayed reply, hopefully others have already solved your problem.

I am using Arduino IDE version 1.8.5. I have not tried more recent versions. Under the IDE ¡°Tools¡± tab I have the following settings.
Board: ¡°Arduino Nano¡±
Processor: ¡°ATmega328P¡±

On the Nextion Display, perhaps try reformatting the SD card and then copy the .tft file as required. When I originally programmed the discovery display, I used the Nextion Editor Ver.1.63.3 via a USB serial adapter connected to the display. I did also check that the .tft method using an SD card which also worked fine.

73, Dave
