New Version of the sketch available,
Now with images, diagrams and adjusting tips, check out the new
features.
v1.3
- Fix for labels on second line not matching real functions (bug
introduced during optimization in v1.2)
- Fix for the diode drawn backwards in the smeter_mod.png file.
- Fix for true calibration of the Si5351, not
just a freq shift on different modes, now it applies a real
calibration inside the lib (USB remains by shifting the VFO, LSB
is truly calibrated)
- We don't longer support the legacy CAL_BUTTON in A2, as every
body knows how to calibrate via the FBUTTON button during
runtime.
- More code optimizations.
- Added the image files for the AGC mod and the TX power meter.

Hi to all.
Since I have now a [borrowed] real bit40v3_smd + raduino I can
test and tune some things...
I have put together a test sketch based on the Allard's code
version 1.15 (1.15 not 1.15.1) that has an S-meter for the RX
part, I'm testing with the TX part [hardware] and playing
[successfully!] with software controlled AGC...
What you get if you dare to test it:
- Full compatibility with Allard's code.
- Smaller code: you need to download the Si5351mcu lib, see
readme and code.
- Smeter on RX, see the simple hardware mod in the
smeter-mod.png file.
- TX power meter, is the same for the Smeter but need a
hardware mod that is on test at the bench.
- Software support for AGC (I'm tunning the hardware/software
parameters, so no schematic for now: soon...)
All this mods can be incorporated on Allard's code once they
are tested and requested.
Do you dare? :

Very interesting, I am looking forward to give it a try.
Any thoughts of supporting a tft display in the future?
Would be a great addition.
Thanks

I think your sketch does fill in a few missing features in Allard's.
Were you planning on keeping your sketch synced with the most recent version of Allard's sketch (now v1.16)?

73 - AL VE3RRD Yes I do, The thing is that here I have not full access (24/7) to the internet and I may be a little behind Allard's code (the time it takes to update the Allard's repository, process and update mine and then publish) Most of the time I must be between 3 to 5 days behind ;-) I have updated the code now, I nee to process it and update mine. 73 de Pavel CO7WT.

Hi Art.
Maybe just I can't explain it wright, please correct me if I'm wrong
in my statement. I'm a Spanish native OM and English is a second one
to me; I will explain in deep here:
Spoiler: the calibration do work fine in the function button, just
we use another more exact trick against the Si5351 clock, not just
correcting the output by an offset.
In Allard's code it does not use the correction of the Si5351 lib,
it just make a offset correction in Hz every time it needs to send a
new freq to the Si5351. That's right and simple, as long as you
don't depart to much from the calibrated frequency.
In the Raduino use case, being mono-band, with a span of about 600
Khz and our ears that aren't capable of sense a few Hz (or sub Hz)
of difference, that approach is simple and fine. More over
calibrating to mid band will minimize the error.
If you plan to use the Allard's code to handle other radio beside
the bitx40 and it covers a few Mhz, let's say a old ham converted
Furuno FS-1000 (real case, no just and example) that can cover 1 ~
12 Mhz, that calibration trick is useless.
That is a OM friend's case, it has that radio and it converted it to
ham bands, put together and Arduino + Si5351 and was using Allard's
code... he calibrated iit against 7.315 kHz on 40m (Radio Catolica
Mundial), then in 160, 80, 60 and 30m it was off but as much as
100'th of Hz in the worst case.
But I have the need to be mathematically correct and fix my friend
error, now he calibrates against WWV in 10.000 Mhz and it's right on
spot in the full range using my code.
For short: the calibrate function works by another more exact way,
and the calibrate options remains on the firmware.
Please advice it the statement in thee readme/etc tell another story
beside this to fix it.

Now I realize your question in deep... sorry.
I removed the old (legacy) way of calibrating by shorting A2
(CAL_BUTTON) when powering on the radio in favor of the new via the
FBUTTON while the radio is running.
Just that, it break old compatibility with former Raduino docs, but
as far as I knows almost all people use Allard's code and knows the
FBUTTON way.

Hi Art.
The limits on the calibration was set to -8000 to + 8000 for my
empiric values so you are getting (+) 8000 and that's top value.
(My hardware needs +3670)
Try to move the dial control all way down to the left, as the
code uses a function that limit the value and I noted now that can
(must) be improved to show the real value on loading... as you
move near the left edge the value must move down and will allow
you to set the proper one.
That calibration routine has a incremental steps when in edges of
the range, and I noted a bug now looking at the code in which the
dial pot is not updated to the real value of the calibration when
entering the procedure, I must fix that.
I will fix and check it as I'm at work and don't have the
hardware at reach now.
73 and thanks for the tip/bug identification.

I use the function button under
settings, calibrate lsb and it reads -8000 ppl. All good? ?Can't
change it. Not that I need to as it is on freq. sorry for my
confusion?

Ok got it. I am using your code
and library (mcu). The freq is spot on and when I look at
the value of the lsb setting it reads -8000 ppm.?
Thanks?

Hi Art.
Maybe just I can't explain it wright, please correct me if
I'm wrong in my statement. I'm a Spanish native OM and
English is a second one to me; I will explain in deep
here:
Spoiler: the calibration do work fine in the function
button, just we use another more exact trick against the
Si5351 clock, not just correcting the output by an offset.
In Allard's code it does not use the correction of the
Si5351 lib, it just make a offset correction in Hz every
time it needs to send a new freq to the Si5351. That's
right and simple, as long as you don't depart to much from
the calibrated frequency.
In the Raduino use case, being mono-band, with a span of
about 600 Khz and our ears that aren't capable of sense a
few Hz (or sub Hz) of difference, that approach is simple
and fine. More over calibrating to mid band will minimize
the error.
If you plan to use the Allard's code to handle other radio
beside the bitx40 and it covers a few Mhz, let's say a old
ham converted Furuno FS-1000 (real case, no just and
example) that can cover 1 ~ 12 Mhz, that calibration trick
is useless.
That is a OM friend's case, it has that radio and it
converted it to ham bands, put together and Arduino +
Si5351 and was using Allard's code... he calibrated iit
against 7.315 kHz on 40m (Radio Catolica Mundial), then in
160, 80, 60 and 30m it was off but as much as 100'th of Hz
in the worst case.
But I have the need to be mathematically correct and fix
my friend error, now he calibrates against WWV in 10.000
Mhz and it's right on spot in the full range using my
code.
For short: the calibrate function works by another more
exact way, and the calibrate options remains on the
firmware.
Please advice it the statement in thee readme/etc tell
another story beside this to fix it.

Just a bit confused on the
lab calibration statement. Do I understand no more
manual if offset via function switch?

New Version of the sketch available,
Now with images, diagrams and adjusting
tips, check out the new features.
v1.3
- Fix for labels on second line not
matching real functions (bug introduced
during optimization in v1.2)
- Fix for the diode drawn backwards in the
smeter_mod.png file.
- Fix for true
calibration of the Si5351, not just a freq
shift on different modes, now it applies a
real calibration inside the lib (USB
remains by shifting the VFO, LSB is truly
calibrated)
- We don't longer support the legacy
CAL_BUTTON in A2, as every body knows how
to calibrate via the FBUTTON button during
runtime.
- More code optimizations.
- Added the image files for the AGC mod
and the TX power meter.
You can check it out in the Github
repository at:

Hi to all.
Since I have now a [borrowed] real
bit40v3_smd + raduino I can test and tune
some things...
I have put together a test sketch based
on the Allard's code version 1.15 (1.15
not 1.15.1) that has an S-meter for the RX
part, I'm testing with the TX part
[hardware] and playing [successfully!]
with software controlled AGC...
What you get if you dare to test it:
- Full compatibility with Allard's code.
- Smaller code: you need to download the
Si5351mcu lib, see readme and code.
- Smeter on RX, see the simple hardware
mod in the smeter-mod.png file.
- TX power meter, is the same for the
Smeter but need a hardware mod that is
on test at the bench.
- Software support for AGC (I'm tunning
the hardware/software parameters, so no
schematic for now: soon...)
All this mods can be incorporated on
Allard's code once they are tested and
requested.
Do you dare? :
