Michel, I made some changes in the scale on the s meter, give it a try and let me know how it works.?
Thanks for testing.

Re: Finding variables in source code
I should add, it has a multi-file search capability which is excellent for searching source code for definitions, declarations, etc.

The Arduino IDE, and most other IDEs include "find" and "find next"? in the edit commands.
This is very similar to the now ancient UNIX grep, fgrep, etc that eventually made its way into?
several DOS editors.? Linux has continued the grep legacy in original and several new forms.
Not sure but I would think that Apple's OSX would also include the function as it was there in?
original BSD UNIX.? It is also present in the shell programming tool for my Linux based?
Android cell phone.

Us real old timers might use use SED (stream editor)to find and change specific words in
one pass.? This is handy for changing all occurrences of a word in the whole document.

I remember GREP from the old DOS days.? Most editors for programming have a search feature. One could also load the code into a text editor and use its search function. ?

I think we all run into situations where we need to find the definition of a variable or object in a large set of files. The UNIX tool Grep is perfect for doing that. The Grep version I use is not longer available, but I just downloaded and tried this version and it seems to work well:
If you want to change the data type of a variable, use Grep and type in the variable name, supply a search path, and BINGO it finds all occurrences of that string in the directory/subdirectories seach.

That looks like a cool mod. I tried a darlington pair in place of the Q70. That works as well.?

I don't have much experience using darlington or compound pairs for audio. ?Maybe I'll try it. ?The 2sc945 mod is not a huge change but it is enough to satisfy me for now.

this is a good explanation

0 dB = 1 volt per Pascal
-24dB = .0.063 V/Pa
-44 db = 0.0063 V/Pa

Hi Malcolm,
what case did you use for your ubitx ?

3.2in Nextion display now looks great.
Many thanks to Ian KD8CEC and Allen Merrill for their great work and time in producing superb operating software and display for the ubitx transceiver , very much appreciated.?

Re: error in memory manager
Thanks, Mike!? That really clears it up.

Thanks Allen,
Yes I configured the S / Meter with Memory Manager and it worked correctly with the Nextion 2.8 and was up to + 20 dB while with Nextion 3.5 he does not want to exceed the S9. I do not think it's very serious. thank you very much

My son and I finished wiring our uBITX v3 (ordered the day before v4 came out) over the weekend.
We powered on and checked out the receiver functions right in the middle of a big contest and 20m was really busy!
My son was thrilled -- we heard stations from TX, OR, CA, and HI in the US as well as Venezuela using an end-fed wire.
A few observations:
1.? The need for AGC was very clear and we already have the ND6T kit so that's modification #2 (after CEC FW upgrade).
2.? The max audio level is pretty low.? Reading the group, it is not clear if there is a consensus on a fix for that but I noticed the Q70 recent replacement thread.
3.? Audio quality is not great. It is hard to describe precisely but speech is distorted and noise has an impulsive character to it.? My frame of reference is a Kenwood TS-130S.
4.? Audio bandwidth is too wide for CW.? A filter would really help.? Again, I'm not finding a consensus solution.
5.? WWV at 10MHz is tuning for us at 9.9985Mhz (1.5KHz too low).
6. Some components are fragile and easily damaged (encoder switch failed during installation, BNC connector insulation melted while soldering antenna wire, etc.)
We're really looking forward to using and modifying this rig.

Re: VE1BWV audio pop fix - lost my sidetone
Hi All,
Had my uBitz for a couple of months and been reading the mail as I have checked it out and made various modifications on the way. Thought i had destroyed it while testing a LM386 amp, but put it back to original TDA amp and all is orking.
Pleasantly surprised a couple of evening ago I had a power meter in line with a dummy load connected and heard bot CW and voice on 40M. Only 8" of coax from radio to meter. Sensitivity seems up to the mark. Getting the uneven power across the bands but with 13.8 V I get some 12 W on 80 and 40 but the usual 3W on 10M.
However I built VE1BWV anti-pop circuit and it works great, but no sidetone. Tried the .1uF in series with R253 but there is a faint sidetone with vol turned up.. I am going to remove it and get the sidetone back and maybe try a different suggestion. Got the Iambic keying working and I am using Ian's ver 1.08 without any problems. Next on the list is calibration although I am zero beating at 10 MHz to GPS locked oscillator. Need to check the BFO for LSB and USB as well.
When I get these going the next is balancing up the power across the bands and then a touch display. A highly functional transceiver where the hardware and firmware are all in the operators control. Still loads to modify and add. Fantastic conception and then there is M0HYT non SMD version, but I cannot find anyway to bring up the printed circuit layers. Much to go on with never mind diving into the code.?
