HI All, just installed a 2.8? nextion enhanced screen on my new v6?
(kit)...added the screen Enhanced tft to the sd card (kingston 32 gb)
new nano in place as kept original one for n8me firmware..Loaded Ian's = kd8cec? firmware? v1.2
using X loader no problems.. Loaded the NX file not the S/NX version,, Powered up the ubitx and up came the new firmware - fabulous..
Haven't done the calibration yet, thats next,? need a pause after the stress getting the?
firmware installed.. Been playing with the screen controls and they all seem to respond
to a touch, except that I can't get the Tx to trigger - no sounds of relays clicking !!?
On the config screen I wanted to change the cw speed and duly started to move
it upwards but on reaching 12 wpm it started to decrease !! no way could I move it beyond 12 wpm !!
Can anyone work some magic ??

Hello everybody. I managed to install the sbitx software on a 64 gb sd, my device now works, and I try to learn the various commands. I have a question: but to put the software on a 32 gb sd how should I do? maybe download the file with another raspberry and do it from there with raspy
?imager. this to be able to learn something more. thanks for your attention and see you soon on air with sbitx. maybe? the? version of? sbitx? are 1.1,?? at? moment are 1.0 . not? sure

Re: PTO without 3D printer
Why is the coil wound that way with the ZL2PD PTO? I have seen that in other designs too. K3bo ? ? Sent from for Windows ?

Re: #sBitx Incorrect frequency display
#sBitx
I¡¯ve seen this issue and similar things remedied by a restart. ?A common one is where you¡¯re tuning and the spectrum display and waterfall shows the same recurring pattern of spikes and bumps, but there are no signals actually coming out the speaker. ?I think the SDR code gets into some weird state. ?We¡¯ll eventually figure it out.
The reason the sBitx would appear to be 600 Hz lower on CW is due to the way it calculates the frequency, I believe. ?All commercial rigs I¡¯m aware of take the CW BFO into account when displaying the operating frequency. ?The sBitx on the other hand uses the PITCH setting and line on the spectrum display to show the user where to tune to get the CW beat note they want. ?The displayed frequency is the actual center frequency, not the frequency one would get the desired beat note. ?This is what I¡¯ve gathered; I haven¡¯t actually looked at the code to verify my thinking.

Re: Daylight again schematic questions
Hi to all
I started this tread to share infos about the best simple inexpensive way to build the PTO coil without a 3D printer?
( the way used by Farhan). ...and now we are talking about philosophy, theology and the sex of angels.....goooooodd for me!
In my sick brain there are three basic electronic laws, if I do not respect them, I pay with money, time, anger, sleepless
nights,, bad mood.?
1) Murphy laws , if you do not know them, change hobby....
2)? P greek laws: don't you know it? Talking with the first builder of an amateur built aircraft here in Italy, he told me:
never forget:? always multiply estimated cost for p greek, always multiply estimated time for p greek, always multiply problems for p greek,
and you will have a quote by default! Absolutely perfect law.
3) My law: tjhere is only one way to solve problems? ( for example class A amplifiers? that heat ): avoid creating the problem! uSDX can be built with
very small inexpensive output SMD transistors and still have some W, that's the digital way........SMDs .....
Sorry , now? I go to the working table again.
Thanks to all
Paolo

I don't want to go any further with mine without knowing if this is the proper bias process or if I have a problem I need to troubleshoot. Anyone have any ideas?

I have had this happen twice and restarting the sbitx software fixed it.
Is this consistently happening to you?

#sBitx Incorrect frequency display
#sBitx
Hello all, I've been trying to find out what's going on with my sBitx.
My sBitx frequency display seems to be incorrect.
It shows about 10KHz higher. Where should I adjust it?

Same here..got it on Wednesday.
Note that there is no tracking, and in my case, it didn't even show up in my USPS daily delivery email. Usually that only happens for magazines and on-off mailings.

Re: sBitx Development Tip
#sBitx
I would need a bigger standing desk to accommodate three monitors! ?hi hi
Your page on hacking the sBitx encouraged me to check out gdb a few weeks ago. ?I honestly never used a debugger before, with all of my C development work on the Arduino. ?I depended a lot on embedded debug code with #defines to turn it on or off at compile time. ?I noticed you don¡¯t have much debugging code at all in sBitx code. ?I presume gdb is giving you what you need? ?I need to learn gdb.
I¡¯ve been using Microsoft vsCode for years to develop for the Arduino, however I find the UI too complicated and convoluted at times. ?Sublime is straightforward and crisp.
I know the vi keystrokes, to the point where I don¡¯t have to think about it, like driving a manual transmission car :-)
But I digress.

Anthony, I need three consoles, one for the editor (vi), one for running the debugger (I always execute under gdb), the third is "just in case" where i can run manual pages, or view another file simultaneously, etc. My solution is to maximize the ssh window and run screen to split the window into three. However, there was a time when I also had to refer to the circuit and pinouts that were running on my thinkpad under kicad and libreoffice spreadsheets. Just wanted to drop a note regarding a development setup that is working well for me.? I had been using vi in an ssh session for development, but that has some real limitations.? Recently I installed Samba on my sBitx to access /home/pi via Windows SMB on my Mac.? I now run Sublime on one screen to edit files and on another screen I have VNC running so I can launch the executable and test the GUI.? For anyone playing with the code, I highly recommend this setup.

Hello Ichiro, I am not sure which default password you are using.? The published one for Raspbian or Farhan's one for the sBitx.? Here is the email from Farhan that describes how he accesses SSH on sBitx and has his default password (hf12345); /g/BITX20/message/9553773 Evan AC9TU

Hello everyone.
I would like to log in to sBitx via SSH, but I can't.
Has the password for the pi been changed from the default?
