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.

...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 开云体育 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.?

Art..thanks!? I had tried reducing the grid? by a few pixels but that didn’t help.? However reducing it by almost a half did the trick.? It does compile and I’ve successfully loaded it onto my 3.5 display.? There are some bugs in at least one of? the pages, but it appears to be close to a workable product.?

Welcome to learning - hi hi

I am stumbling through also

?

If you reduce the grid size on that page say by half for x and y it will compile. I don’t remember the I’d number but it appears in the upper left corner in the grid. Select it an the attribute page will come up. Go to the bottom and change the h and w values

Lots of other things need fixing but am encouraged others are working this also.?

Re: uBitx Unfiltered

 

I would say LPF for 60-30-17-10meters bands and eventually 160m if you would like to use this band too (I think it could transmit as well on 160m)

I haven’t even build my uBitx yet. Maybe in the winter. Where can I have a look at these LPF’s from Hans. It’s not a killer for me. I’m sure I can still have fun with the radio, it will definitely be a digital mode radio for FT8 for sure so as long as it has a few uses, I’ll be fine. I’m not looking for perfection.?

Re: UBITX V3 TX GAIN VARIATIONS

 

Jim,

Try this input to q90 Isolate the other stuff from loading the input to the amp,
output at T11 before the filters (cut trace).??
Doing that requires tracking generator but yyou can sweep it by hand?
using a any RF generator (measure direct then measure through).

Run that at 3db/division to see the droop is power and gain.? When I've done
that on many samples they all sag about 10-12db from 3-30mhz.? Its not the
IRF510 its all in the stages before it.? The IRF510 can be flat but in that
design it also sags about 2-3db because, long leads, transformers not
optimum, board layout.
