I'd actually enjoy that. Talk with the FDIM people to see if they have any interest. Preston Douglas (pdouglas12@...) is the President of the group and would likely be the one to contact. However, I would NOT do it now, as FDIM starts in two days and I would imagine he's buried in details right now and would likely say No to anything right now! A week from now might give him enough time to unwind from the conference.

You gentlemen seem to have such a great time discussing all of these changes and ?what should/could be a standard load from the start. ?I have been studying my Arduino starter kit and one of Jacks books but still have a long way to go.

Possibly next year at FDIM and at Hamcation, Hamvention and even Ozarkon one or two of you could put on a seminar about this issue and maybe even help some of us upgrade our rigs (both of them) in a special session. ?We would bring our radios, laptops if necessary, etc., and go step by step installing the latest code and then have an explanation on how to make it work. ?I would even pay a fee for such a class. ?It could be like in my past medical conferences where it was early in the morning before the rest of the session started or during the afternoon when the rest are out seeing the sights. ?These sessions were called "special interest groups".

I just need to see someone do it the first time (load in new code) with a step by step explanation and then the light might go on.

Is something like this possible?

I looked the board over closely and did not see a WX anywhere. Written in ink beneath the audio connector is U6666/3. I don’t know if that is the serial number or not. Aggravating because I never got the first signal. Was headed to 10 MHz when it quit.
Will try to do some trouble shooting.

Just finished putting together uBitx in the Amateur radio kits case.
Turned it on and tuned, heard lots of squeals. After about two minutes
of looking for a signal with minimum antenna the audio quit and cannot
get a sound out of it at all. Any ideas? seems like the tuning and
setup still works.

Good question, which I will leave for someone else to answer because I don't know. ?My guess is yes.

One error in the schematic I sent. ?The 12K resisitor in the TX voltage divider should be 15K in order to have the best audio on SSB with the filter at full bandwidth.

My plan is the longer version of the BN43-6802 (or use two BN43-302 end to end).

Amidon has the 6802, Diz/Kitsandparts has the 302.

I? have to order some MPSH10s for driver mods.

Ashar *does* support the software he provides. Significant testing was
done before it was used as the standard load. While it does have some
problems it *does* work, it *is* usable as provided. And it provides a
stable base upon which to build.

When was the last time someone reported a problem with the standard
software that prevents it from working correctly?

Jack,

Respectfully, you missed my point. I probably wasn't clear. I didn't
mean a "coding" standard. I meant a standard software load with defined
functionality.

Trying to add functionality that others might want to use, in an
environment of multiple conditional compiles, becomes a true nightmare
of regression testing to insure the added functionality works with all
combinations of the conditional compiles.

Not doing such regression testing and throwing a software modification
out into the wild means many users are going to find that their
individual software load no longer works as intended if they try to use
the software modification.

For instance, your mention of deleting keyer code if you never use CW.
If I develop functionality like a "Tune" option that requires the CW
transmit module and some kind of a CW key to transmit a carrier, it
won't work with someone that has deleted the keyer code using their
conditional compile. If they add my functionality what's the first
thing they are going to see happen? It won't work. Who then gets to
figure out why and then who gets to fix it?

I agree with Ron, here. Tim's statement:

????It's important to have a *standard* to write to.

would be nice, but as we all know, there is a difference between

coding style and functionality. Cut-and-paste code is also nice to

have, but any code may be useful if you can read and understand it.

To me, the litmus test of good code is code that can be read and

understood easily. When that's true, it becomes much easier to adapt

it to your needs. Simple things like using #define's instead of

"magic numbers" make it easier to read and adapt code. (If the IDE

had a symbolic debugger, I might use constants, although symbolic

constants are typeless and that can be a huge benefit in writing

reusable code.) Writing "clever" code is rarely a benefit. Which

would you rather read:

?? a = b >> 1;

or

?? averageVoltage = baseVoltage / 2;?? // Voltage divider derives

average voltage that's applied to pin AVERAGEVOLTAGE

Perhaps the only real reason the first version might make sense is to

cause some speed gain in the executed code, or perhaps save some

memory. Even that, however, often makes no sense because the Gnu

compiler is quite good at optimizations. Indeed, my guess is that the

two forms above generate exactly the same code. You can examine the

*.lst file to get a feel for the final answer.

The final step before making it available to the public is to ask

yourself: What can I do to make it easier to read and understand this

code? If you cannot find changes that enhance readability, it's read

for prime time. Even then, readers will have difference preferences

on the way they would write the code...that's to be expected.

However, the fact they have preferences means they can read,

understand, and hopefully use the code.

For reasons most can guess, I have not read Ian's code recently, but

I'm sure it's readable. The fact that Farhan has even suggested using

it as the standard means he's happy with it. If it's possible to

conditionally compile the code (e.g., why have a keyer if you know

you'll never use CW, leaving some room for additions you know you

want), it seems to me to be a moot question.

And to those who argue: "But conditional compiles means the users

have to be able to change the code!" Yeah, so what? If you can't

change the code, you still have several options: 1) accept the radio

"as is", 2) learn enough programming to make the changes you want, or

3) pay a programmer to implement the changes you want. Trying to get

a boo-hoo from me for people who don't want to invest a weekend in

learning how to make such changes is pretty much going to fall on a

deaf set of ears. Besides, this kind of programming is going to get

more important down the road, not less. May as well bite the bullet

and jump on board...you may even find you like it!

he could not cut-n-paste my code into his firmware because he used

As he stated in his description of his keyer routine, he looked at my

And as all good programmers do gave me acknowledgement in his header

of his keyer module.

So you don't have to create code that can be cut-n-paste to be

useful.

John,

If I am writing a function that others might want to use, how do I

know which analog input to look at for a trigger by the CW key?

Does my function need to look at both A3 and A6 just in case? Or do I

use one or the other and let the user worry about fiddling with my

code to make it work?

It's important to have a *standard* to write to.

I disagree that the original software is a good starting point for

I think the uBitx should be shipped with a software that best

promotes it's capabilities. That way the user can enjoy it fully

without having to go through an upgrade process that he may not be

willing to go through.

Making room for later software changes is easy if, as said above, the

software is segmented and shows the "memory cost" of each option.

As an example below is the start of the my ubitx_20.ino file, based

on Ian's 1.061 version.

It is easy to make room by commenting out options to insert one's own

code if desired, or simply enable "extra features".

//================== Compile options for adding/removing features and

saving memory =====================

//When there are no hardware modifications (i.e. wired as per the

HfSignals web-site) // If UNdefined, or commented OUT, assumes that

the CW key is connected to the PTT input (A3) to free-up A6 for //

the handsfree option here. (note that A6 could also be used for SWR

or supply voltage monitoring). No memory impact.

Whoops, a USB sound card gives you stereo sound output. Plugged into the mike connector for digital work it activates the PTT line with the audio!
The CAT interface works find for PTT and frequency control.
It took me forever to realize the orange PTT wire needs to be disconnected for digital work.

I made a bit of progress, getting a copyable RTTY signal with fldigi on my nearby rig. I couldn't get FT8 to copy. Experimenting with proper audio levels is driving me crazy but I'll figure it out.

The receiver surprised me, with me copying PA & NY on FT8 WHILE CONNECTED TO A DUMMY LOAD. I hope my transmitted signals didn't get out too.

I happened to have a 5v fan that fit the 3d printed panels I bought. I used a 7805 to drop the voltage down. Kinda noisy, going to drop it down to 3 volts. or so.

One awkwardness - the rig runs off of 12 volts which runs thru the power switch. However the usb interface activates the LCD whenever it is plugged in. How many times have I scratched my head with it when it wouldn't transmit even tho the display said it was, because the power switch was off. A solution would be to cut the +5v lead in a USB cable I guess.

In the meantime, a simple CW QSO is in order.
