Dennis,
Warnings are not errors.? If it compiles and links you are most likely all good to go.
This code has obviously been used and tested by others.
As far as warnings go, all that matters is that the assembly code generated works the way it is intended to work.

If this was a commercial radio, you would have bought it without open source firmware, and never even considered if the source code was warning free on compile.
You just care that it works as intended.

If you are getting 50 "Errors", something else is going wrong for you.
If you post the Errors, maybe someone could help you.

Regards,
Gary

Does the ubitx code rely on other libraries like "wire"? Missing libraries are a common cause of compile errors.?

I have installed many libraries over time, I may have needed dependencies already installed, so I don't know if the code won't compile for need of libraries when people are starting from scratch.?

Go to "Sketch", "Include Library", "Manage Libraries" to find libraries you may need. The error messages should mention what can't be found, and needed to be installed.

The 33uh sounds good. That can be wound on? FT30-43 if you have them?
or any 43 material bead.? ?You can just use a resistor, you get a little less
gain maybe 1-2db but it works well.? After all gain higher than 30mhz is
not used.

The cap use a .01 or .1uf.? By MMIC standard 3mhz is DC
but the cap need to be near zero ohms at near DC (3mhz).

Oddly I have a limited supply standard MAr types.? Plenty of
ERA-4,5,6 and Gali (sot89 device).

This has been an "interesting" activity so far.

As of today, there have been 403 paid orders for AGC and/or Click Mini-Kits and 399 have been shipped. I have additional boards and parts and will continue to supply these Mini-Kits as long as there is demand. Details are in the "Files" section under my call? K5BCQ

I have been somewhat surprised to be able to process such a qty over a short period of time. That indicates there are opportunities for others to join in with their ideas. The uBITX is a great vehicle to roll up your sleeves and modify/improve.

Hi,?
So what do I do about the nearly 50 error messages? I am just learning how to program in Arduino C and this is way above my skill level. (I'm only 67 pages into Jack's excellent book).

I found some msa-0386 mmic's in the junk box. It's been a long time
since I've used any of these. They are much like a MAR-3.

With a 12v power supply I'm sure you want to use a 200ohm resistor to
the output pin. That will give you 5v at the mmic with a 35ma current.
But I don't remember what to use for the blocking capacitors and the
power choke. I'm guessing around .0047mf and around 33uh for the choke.

This would be quick and easy to build up if someone could confirm these
values.

I like the idea of a daughterboard underneath. I'm pretty sure the
choke could be wound on an ft37-43 or ft37-61 and still fit on the
bottom of the board.

Actually I'm not sure the choke is even required at the frequencies
used in the ubitx.

Comments? Suggestions? Critiques?

Very cool, that's all making sense.

So the 12mhz and 45mhz IF amps on transmit should both have around
12dB of gain. Could replace Q20 with an MPSH10.
Or could reduce gain a 45mhz to 8dB, increase it at 12mhz to 16dB,
and continue with all 2n3904's??

Additional gain in the transmit drivers could be had by removing C82,
then adding a daughterboard glued to the back with connections to T8
pin 5 and the top of RV1.?

This daughterboard could allow us to reduce gain in the existing 3
stages of 2n3904 transmit drivers. I think many with working rigs
would be hesitant to replace all the 2n3904's from Q90 on. Nice if
any mods kept to a minimum and easy to reverse, the daughterboard
helps in this.?

I was assuming most of the trouble was at the clk2 mixer, as gain doesn't really get
out of hand till you have both TIA's in series.
Rather surprising that an extra 4dB gain at 12mhz into the clk1 mixer would be such a bother.

On the other hand, we're pushing it big time with only the 30mhz LPF before going into the power amp.
As you have said, pretty much every other multiband rig has multiple bandpass filters there.
Getting by without those means being extra nice to the mixers.

If the worst of the required hack is that we need to add 17dB to the TX drivers, that's not sounding bad at all
Remove C82, add an MMIC plus two caps and a resistor to the back of the board.
Could be done in a variety of ways without a custom PC board,?
I've etched lines using a dremel cutoff wheel into scraps of pc board much like ND6T favors,
that's good for SM parts because it gives good mechanical support.

An old Swan 100MX I bought new in the early 1980's is the only commercial HF ham gear I have.
Not unlike the uBitx in many ways with simple controls, mostly discrete parts, easily understood.
Though the bandpass filters plus all the local oscillators and their filters double the complexity of the rig.?

I disagree with the finding that it behaves the same on the Mac.
At least on Ubuntu it just worked as advertised no renaming or removing of files requuired.

On the Mac it creates a duplicate file with again duplicate content.

For me the manual process by as shown above was what worked.

Misspell in the link, good ol' typos!

Get us all.

Thanks Karl !!!!

Finally I understud about the duplicate file. I was still focussed ont he duplicate directory that is automatically created when you select "OK" when the Arduino app to create the new directory etc etc etc Whle all I had to do was remove the redundant .ino file and only leave the "raduino_v1227.7.ino" file in place.

I have included a screenshot of my file structure containing only the data that is needed so it's clear for other Mac users what it all should look like.

Been hearding electrons for over 45 years.? It always makes sense even if its not obvious on first glance.

>>Or could reduce gain a 45mhz to 8dB, increase it at 12mhz to 16dB, and continue with all 2n3904's? <<

Can't do that as the 12 to 45mhz mixer is still being overloaded as well as the 45mhz to signal frequency mixer.
Sure the 45mhz filter takes out some of that but not a lot.? ?As was the gain of the 12mhz IF was greater than
17db, 6-7 db too much.? Its the sequential overload that is bad.? Two overdriven mixers are not a good thing.
The other negative thing is more IF gain than needed puts the carrier to modulated signal lower as you have
to turn down the audio drive to get fewer spurs.

Since Farhan used TIA in a bidirectional arrangement we can tailor the gain for one direction without
bothering the other.? This way we don't break the receiver.

You understand the path to flat power gain.? Rather than forcing the transistors to
deliver nonexistent gain we limit it to what they can deliver at all frequencies and
supplement the missing gain.? But that is nearly 17db.

Yes I know the feeling, hi
But sometimes fool-proof automation can have its advantages.
Anyway thanks for confirming. It means that basically the installation instructions are identical for Windows and Mac (and perhaps Linux too).

The Mac version behaves the same way as what you are describing. My process is however slightly different: I clone?the project and then rename?the project folder - and then delete/rename/move anything that should not be there. Whenever the Arduino IDE asks me if I want to create?the corresponding folder, I always feel like I made a mistake :)?

Thanks Karl Heinz
As you pointed out, there should be only one .ino file in the project folder.
The github repository incudes two ino files, but the project folder should only have one ino file in it.
Normally the IDE will take care of this automatically. It shouldn't be neccessary to delete or rename files manually.

But perhaps the IDE behaves slightly differently on a Mac than under Windows or Linux?

This is what I normally do under Windows:
1. on the github page, press the green button "clone or download"
2. Open the downloaded file "bitX40-master.zip" and extract all files to a location of your choice
3. Go to the extracted folder "bitX40-master" and open it
4. Inside this folder there are several files. Find the file named "raduino_v1.27.7.ino" and double click it
5. The Arduino IDE will start
6. A message box will pop-up: The file "raduino_v1.27.7.ino" needs to be in a sketch folder named "raduino_v1.27.7". Create this folder, move the file, and continue?. Click YES.
7. This will create the sketch folder with ONLY one ino file in it.
8. When you go to Sketch => Verify/Compile (or press ctrl-R), then the sketch should be compiled without errors.

When you follow exactly these steps, does this not work on a Mac?
