On the Site it says ' The Low Pass Filter kit can handle at least 10W safely' so it will.

Re: compiling ubitx ver 4.3

 

I extremely disagree!? As a hobbyist we have NO schedules and NO budget constraints!


There is no reason not to produce clean code.? It's called being LAZY.


There are a lot of people that look at our code and try to learn from it.? Jack has written many posts

about proper coding which most people just ignore.

Re: uBitx Unfiltered

 

MRM,

Depends on how the testing turns out ;o)

Haven't decided yet. Anyone can order boards with the Gerbers and share with friends using the "$2 for 10 boards + postage" deals several board vendors have. I uploaded what the artwork looks like to the "Files" section under my call. The 4x version is specifically designed to work with the existing uBITX and use it's LPF parts. Feel free to ask questions?

I built the probe per N5ESE's website and it worked.

I was able to trace RF during TX to C80, but nothing at C84.

Turned out there was no continuity between the relay K1 pin 1 and R84 on TX.? I fixed that, and now there's RF energy getting to the antenna connection and the IRF510s are generating heat when they are supposed to.

However, nothing is showing up on WSPRnet or PSK Reporter, so there's some more work to do.

Thanks to everyone who helped me get this far!

I have Gerbers for 2 different LPF relay boards. Both support the Hans Summers plug-in QRP Labs LPFs. One has space for 4x LPFs like the existing uBITX LPFs and uses smaller Omron DPDT relays and the other has space for up to 6 LPFs and uses the "standard" DPDT relays which uBITX uses. The 4x board has a diode dot OR which makes it compatible with 3 existing Raduino control signals. The 6x board has 6 individual control lines which could be a 6x rotary switch or some type of decoder/driver which could interface to the 3 Raduino control bits (would require a code change for proper LPF selection).

Presently undergoing testing but the Gerbers will be made available.?

Re: compiling ubitx ver 4.3

 

Perhaps I'm just old and in the way, but this "char literal to char" warning seems a bit much,
If the compiler saw where I was later assigning a different value to that char, then it can complain
And I would not.

If you want zero warnings when especially fastidious checking is turned on,
you might be re-writing a bunch of libraries.

Thanks, Gordon!

> Board was laid out correctly with respect to their polarity when installed on top
...which indicates to me that it's meant to be a 'hat' above or 'mat' below the main board, and populating it wrong-side to install upside-down is itself wrong.

Re: compiling ubitx ver 4.3

 

In one case, I've worked on some of the Google TensorFlow ¿ªÔÆÌåÓý code. Was the Google code free of warnings, no, not at all.?

Often the C++ complier introduces new warnings that are due to improvements in what the compiler can detect or pointing the direction to what is coming in the next versions of the language that will be?deprecated in the future. So, fixing warnings is a matter of judgment and priorities.

A great case example of overzealous commitment to no warnings allowed was a case where someone made no warnings allowed their mission and set the -Werror flag on release code. There were many people working on projects that relied on that code. So along comes a new release of the C++ complier and hundreds of projects are halted and much time wasted (days) until someone could track down the issue not being a real problem, just a ill-advised complier flag setting. The person defended their position to set that flag in spite of the hundreds of person days lost by users.?

In the development build chain, warning free code is a good aspiration. But even companies will weigh the costs of refactoring code against the benefits. Often warnings are generated by included libraries, so unless you have the time to rewrite those yourself it is necessary to wait until the maintainers of the library can prioritize fixing and releasing a new version.?

Re: compiling ubitx ver 4.3

 

I agree that warnings and errors in released code detract from the apparent product quality. In one of my jobs I had to deal with 90,000 warnings in one release. Everyone told me that they were insignificant and fixing the warnings would require massive effort, so they simply postponed dealing with them until the final release. I could not stand the situation and started pruning through the code. After two weeks, I uncovered about 100 serious issues and with the help of others (who started paying attention to my work) managed to bring the number of warnings to zero. Only after the value of my work was recognized, the rule became "Zero Warnings".

The above demonstrates that warnings should not be ignored. However, the advantage of open source software (or for that matter hardware), is its transparency. Greater progress can be achieved when hundreds of eyeballs are scanning the code. This is a collaborative effort that requires group collaboration. Maybe a strange concept to people who are used to only consume... If you find an issue in the code, fix it and contribute your fix to the code repository. At least contact the author and request them to fix it. By complaining, you will achieve not much.

Re: compiling ubitx ver 4.3

 

Kevin and MadRadioModder

The Raduino seems to have brought some of us old geezers out of hiding after 10 to 30
years of non-coding.? Since some of us learned our C-language from Dennis Ritchie and
the K&R manual we may not be up to speed with all the changes in C-code standards nor
be using the latest compilers.? This does not fix the warning messages situation but may
explain how some of the present day code is not up to latest standards.?

Part of the problem is that there seem to be several competing standards and slightly
different compilers depending on whether one is using Microsoft, Linux, BSD, Oracle,
IRIX, Solaris, or OS-X as the programming platform.?

So we depend rightly or wrongly on you professional programmers to help us get up to
speed with the latest standards and techniques.? While most will be using some variation
of the GCC compiler, it may not be up to date with latest standards if a new version has
not been installed for a couple of years.? Others using a Microsoft compiler will find a
few places where GCC C++ code might throw an error, and vice-versa.?
