Hi Gary,

That's a bit of a surprise... Do you have two versions of the Arduino IDE installed, perhaps? Back in the old days, each Arduino got it's own folder, but if you install in a common folder, the installer might do weird things? I'm thinking maybe if you try and install an old version on top of a new version, it may not replace the newer files, or something like that.

A few things to check. First, if you open up command (press windows key briefly to get the search bar up, then type "cmd.exe", then press enter to open), what output do you get if you run the command "C:\Program Files (x86)\Arduino\hardware\tools\avr\bin\avr-g++" --version ?
Here's the output I get:
The important part of this output is the "5.4.0", which is the compiler version. If you get a different value, that could be part of the problem. It looks like they jumped to "7.3.0" by the time they got to 1.8.13 ()

Next thing to check is the library version. I don't know of a good way to check the core libraries, but we can use the bundled libraries as a proxy. For instance, in C:\Program Files (x86)\Arduino\libraries\Adafruit_Circuit_Playground, I have a library.properties file that reports 1.8.1 on the second line. This appears to have been updated to library version 1.8.6 for IDE version 1.8.10, so if you see something newer than library version 1.8.1 (and haven't manually updated it yourself), then you may be looking a new files there too.

Given that this is probably going to be an ongoing problem for new folks, I might make another "final" revision that cuts out a bit more "fat" (like the bands Ron did /g/BITX20/message/79962 ), that compiles on the newer IDE...

Hello,

I apologize. I should have read. This thread is about the same error as I have posted an hour ago.? I should have read better.

I have downloaded 1.8.9 and am still getting the sketch to big error.

Gary

Hi David,

You can download older versions from the older versions page:

Hello

I am having trouble compiling Reeds sketch.? I have even installed the Arduino IDE 1.8.9, the one Reed developes with because the newest and the next one were giving the too big error.

I went to

Downloaded the zip.? Unzipped it.

opened it in IDE version 1.8.9 and pressed the verify button.

The too big error showed.

What I am doing wrong?

Gary

That is a winner, for sure.?

I may print this out as well - a 3D printable tilt-bail.
Not nearly as nice as the ones from QRPGuys.

Like Ron said, for whatever reason, the 1.8.13 version of the Arduino IDE bloated making the sketch too big (reported here: /g/BITX20/topic/75008576 ). In the Readme file you'll see I explicitly called out that I developed using 1.8.9 . I'm not sure if the bloat issue will be resolved in newer versions, but the older 1.8.9? should compile without issue.


Reed

You guys keep posting great info!? ? ?I just received the TSW Teensy kit and will install it soon, but will probably get the NEXTION just to try that too!? ? Thanks everyone for contributing to these threads.? Reed, if you end up writing code for the Teensy or ESP, I'll be trying that out too.? ? Thanks much for making this a fun expedition

Reed,

Almost there with using your version but got an compile error that said "Sketch too Big" and "Global variables 819 bytes(39%) leaving 1229 bytes for local variables maximum is 2048 bytes."? I have a fair amount of experience with Arduino Uno but I'm not sure what to do with this problem. Really looking forward to trying your version.

Hi,

The folder "hardware" contains the kicad files but also a file "remote3_sch.pdf", 4 pages with the schematics in more readable form. The *.png files gives you an impression of the PCB layout.? I currently do not have pictures of the remote hardware for now, sorry.?

73, Jean.

Once you go through the math you will see these numbers relate to hardware, and that the controller code has appropriate default values.

BFO calibration addresses variation in the quartz crystals,? so calibration must exercise the receive chain. It can be done decently by ear, and verified by listening to both sidebands of an AM signal. Or using an audio FFT analyzer. Look here and on the web for methods. BFO calibration is vital to good reception.

Hi John,

Assuming you're using the stock v6 software 6.1, then you'll see the first IF is set to 45.005MHz


The usbCarrier defaults to 11.052MHz, but is whatever your BFO calibration is set to


Finally, the frequency of clk1 is set to the sum of those two for USB, so in the default case, 45.005+11.052=46.057


Clk0 is a bit easier: it should just be whatever the BFO is calibrated to be. So again for default, that would be 11.052MHz, but if your rig already has a calibration, then it should match the frequency of that calibration.


I don't know exactly what your BFO is calibrated to, so I can't tell you exactly what frequencies to expect. However, a reading of? 33.95 MHz on LSB mode would imply a BFO calibration of 11.055 MHz, which is in line with what I'd expect. Do you have reason to believe your radio is incorrectly tuned?


Reed

Ron - The Teensy has the code space for such luxuries :P

Guy - most of the stuff I added was already in other software builds for earlier or hardware modified versions. If you haven't already tried KD8CEC's software on your pre-6 rig, you might give it a go.


Reed

Thanks Reed. Makes me almost want to get a V6 just to use your software. Seems to have a lot of great features.

73,
Guy WB7SZI?

Ron,

I don't think it would be too difficult to modify for v5 (or even earlier). But unlike the KD8CEC software, I haven't set up nice #define switches to change between versions.


Reed

Great write up! Thanks for sharing your setup and design decisions so clearly.
