Hello Erik,
???? I? really don't like to add even more to your "to-do" list, but as and when you can, I wonder if you can add at least one of the early .ino files to the github (or Forum files) collection.
???? I have two reasons: One is that I prefer to start with the simplest version, and only add the bells and whistles when that is working.? The other is that I want to change it (if? necessary) to provide a tester for single Si4432 modules, because of the stories about the ones that I bought only giving an output of -15dBm!
???? In case you reply that the later versions would perform the earlier functions, I will add that the early file (that I have lost!) compiled ok and ran in an Arduino Nano. But the later files with the rotary encoder, attenuator and display just give me chains of the usual incomprehensible (to me) error messages!
I know that you have done enough already, so thank you either way.

IF you take the ino file from github and delete all these defines

there should be nothing left of what you do not want

I decided to create a github account create a MS Visual Studio Dev Essentials subscription to review the VS versions to download.? Well... ~900MB for the 2010 Express seemed better than the Visual Studio Community 2015 ~4GB for now ISO.? So downloaded and installed and began reviewing another applications code I was shown. Seems easy and intuitive like VS 2003.NET and 2005 Pro (more like).

However, I am wanting to review this apps code (tinySA) and am guessing is derived from the Tapr-VNA... though haven't loaded and read into yet.??

Any advice regarding any differences between the tinySA before I start reading into??

I'm not planning to make any modifications and if I do, I'll read into github processes more and do what looks like a fork/branch into my jafinch78 account.?

Time to study up the differences between 2003/2005 versions and learn some C# as I've not programmed in before (only VB or C++ with VS) as well as learn how to interface input devices.? Thanks in advance for your time.

TinySA PC software is not public domain

Tony, not trying to hijack your thread - but which modules are the good one? Anyone know - like an eBay/Amazon link or something? There must be a million of those things!

Erik's build instructions say
??The SI4432 modules should be something like this:

That's an info page, the product you want is probably this one:
? ?

Good news:? cost of $2.60 USD (plus shipping)
Bad news: "Due to the quarantine of coronavirus, we will be closed until 10th, and starting to send order after 10th."

I tried downloading the RF22 Arduino library they point to in that info page.
Full of object oriented C++ to create mesh networks and stuff, I'm sure it's very cool.
But not my cup of tea.

Dan,
These are the ones I bought.? I bought 3, am currently using 2, they seem to work great.
The third I have removed the filter parts as per Erik's instructions, but haven't used it yet.
These seem to be the same modules as Erik is using:



Can't beat the price (at least when I bought mine, these were the cheapest I could find!).

Hello Dan,
??? Sorry for the delay , I have been? busy still trying to use various .ino files without sucess.
To answer your query; If you do a google search for "Si4432 module warning"? I think that
you will see the appropriate information. It is a forum message (though I don't know what forum) and shows three red PCBs (one works, one is poor and one is bad). Guess which ones I bought! There is also a blue PCB which is said to work.
??? Banggood do that one. So as I have got nowhere? trying to test the ones that I have I will order two from there in case I get back to this project someday.

These so call "bad"? modules are mostly 250MHz or 333MHz modules used ad 433MHz.
Make sure your supplier understands the different between the frequencies and only buy from a supplier (click on the name of the supplier and visit their store and look at their rating) that is selling many RF components and not someone that bought some leftovers and is trying to sell without a long established reputation.
