Thanks Bob!? The "N/C" meaning "Normally Closed" makes sense.? Should have realized it myself!

Jerry,
I agree.?
The various STM "pill boards" sound promising and are --very-- cheap.....did you know there are 17 different STM32F103 products out there and the STM32F103C8 is one of the "simpler" chips. The chips themselves go from 36 pins to 100 pins. I see they all have a RTC.

Thanks to everyone for their accolades. Glad most find the wiring diagram of value.?
Patrick:? The original file is a CAD DWG. Writing it out as a PNG should be doable. Having it live on your Wiki with others contributing versions for the various sketches and mods would be outstanding.? I'll post a PNG version for you.
Jonathan: The dotted line in the jacks was a way to show a connection between the N/C (normally closed) pins.? Once a 3.5mm plug is inserted the N/C connections open.
Finally thanks to all who found errors in the original HF Signals schematic and wire-up.? Bringing those to the attention of the group made the process of creating the diagram much easier.

There's thousands of people on this forum with thousands of different opinions
of when it's appropriate to start a new thread.
I'm perfectly fine with having a conversation that goes somewhere.
And if it goes somewhere, I don't want to have to hop through a half dozen
threads to follow the train of thought.
Nor do I want 20 different threads about various microcontrollers to consider.
For example, this post is off topic.
If somebody wants to start a new thread about when to start a new thread,
I'm fine with that.? But I happen to have chosen to just continue the discussion here.

Yes, the "RobotDyn SAMD21 M0-Mini" is very similar to the "Protoneer" but 2x to 3x more expensive and I don't see any advantage, offhand ??? ?

Yes, the STM32F103C8T6 boards ("blue pill", "black pill") are another very low cost (<$3) alternative and it looks like the market is being flooded with them. It will require someone more experienced to evaluate the possibility of a Nano upgrade and just how well the Arduino IDE works with these STM parts. I guess you can get them with 32KB or 128KB of program Flash and 20K of RAM.

I have a CW filter from New England QRP the NESCAF switched capacitor audio filter. Mine works great with the uBITX and others have had good success as well.? It lets you very both center frequency and the bandwidth.? Mine will go from a bandwidth of about 1.5 kHz down to about 80 Hz. In many cases it helps eliminate some of the higher frequency audio noise for SSB operation.? ??

Because the INO file must have the same name as the directory its in for the IDE to compile the file, instead of all versions sitting in a directory name ubitx_20, it makes sense to have:
C://ubitx_20V1072/ubitx_20V1072.ino
????????????????? ubitx_factory_alignment.cpp

???????????????????????????? This way the "old" versions are preserved when the new one is released. I would still like to see only the source file containing the setup() and loop() functions be given the INO secondary file name and all the others given CPP secondary file names. Currently, using all INO file names causes the compiler to get sloppy on parameter type checking and that can be a nasty bug to isolate, especially when no symbolic debugger is available. True, the change will identify a host of warnings, but should uncover no bugs, since the code compiles correctly as is. I did that for Farhan's original code and while it took some time, it's really grunt work and not difficult to change.

I use git for version control, but it seems to be difficult to trace history when the file name changes.

All filenames are now cleaned up.
Since Version 1.070, there was work such as splitting and merging files to support various hardware.
I will publish Version 1.073 (Beta) within a day.

I am just waiting to receive the micro bitx then I will start the experimentation. The idea is to use the bitx as a development board for the additional am/fm components. Meanwhile I started to create the schematics in eagle because in the end my? target is to have a handheld bitx with ssb/am/fm so i will need to design a new layout to fit in a handheld case. For the Fm part I will use a demodulator ic on 455khz, maybe a Sa605.?

Karl:
You're probably right on the 3 types.
However, the statement:

needs a little wiggle room. If someone
just wants to add a splash screen with their
call, that's a change, but I don't think
they need version control to do it. The
problem is implementation: at what point do
you transition from casual programmer to
software developer? I think there are a lot
of "add-a-splash-screen" programmers who are
sticking their toes into the programming
ocean for the first time. I think that's
great...it's a fun element of our hobby! Of
course, the danger is that wigglie toes in
an ocean can attract attention from some
mean-spirited creatures and some cautions
need to then be put in place to safeguard
the code. I just don't know where that line
is drawn.
For me, when I'm finished working for the
day, I always make a back a copy of the
current files into a Backup directory.
Using my earlier example, I would have:
??
C://IanLee/Version106/ubix_20.ino...
?????????????
/Version1072/ubix_20.ino
?????????????
/WorkingVersion/ubix_20/ubix_20.ino...
????????????? /Backup/WorkingVersion/ubix_20/ubitx_20.ino?
// and the rest of the files
Notice how Backup is really
a mirror of the WorkingVersion
directory. As long as I back up at the
end of each day, my worst case is I lose
one day's work. I'm not as religious
about this as I should be, which a real
VC would enforce, but it works for me
now.
In the end, it's up to the user
to decide what's needed. The true
value of VC only comes
clearly into focus
when something really bad happens
and six months worth of work
disappears.

1) The "Give me a simple way to flash

numbers, I don't care about changes, I
just want to use?the latest and greatest
features" user. For?them, a version
number is not important,?because they
very likely don't even want to keep more
than one version around. They would very
likely be happy with just using avrdude
and flashing a hex file, which Ian
provides.?
2) The "I want to experiment with the
software and make my own changes, but
always want a save way to get back to a
working configuration" type of user. For
them, just like learning?the syntax of
C/C++ and how the library system in the
Arduino IDE works, it may be a good idea
to get a basic understanding of a
version control system and use that to
keep track of changes.?You want to make
changes to the software? Then you are a
software developer, and version control
is part of that.?
3) The "I want to have access to
different versions, but don't?want to
learn how software development actually
works" type. For them, your approach may
be a good way to keep track of different
versions. ?
Especially if you fall into #2, and you
want to make changes, you need a way to
figure out what you've changed. When you
hack away on a keyboard, mistakes happen
and you may not even remember touching a
file. A version control system always
will tell you exactly what has changed,
and then you can figure out how to get
back to a working system. So, in m
opinion if you?want to make changes, you
either need to be very good with the
Unix diff command, or have a VC
system?that takes care of that for you.?

The reason the Raduino regulator greats so hot is it has to dissipate the heat generated from in your case the 8.8 voltage drop across it. To cool it down you can insert a dropping resistor of about 56 ohms inline with the regulator input from pins 15 & 16 of the Raduino control board. Just cut the trace between those two points and solder in your resistor. You want to select a resistor value that will keep the voltage at the regulator input at about 7 vdc.
