Beginning work on a version 2 of my SWR+VNA meter (ROES). Using a new much larger full color touch display. I have some debugging to do but it partly works with existing code, so yay.I will be completely redoing the UI to add colors and various graphical representations such a Smith Chart showing the complex Reflection Coefficient (Complex SWR).I will also be adding an extremely accurate frequency counter up to 2 GHz to improve the accuracy of the device and include a frequency readout on the display.#HAM #Engineering #RF #HamRadio #RF #EE #Electronics #Arduino #AVR

@snder Thanks, it has been a fun project and advanced enough for me to learn some new tricks.

@freemo Hardware isn’t my thing 😬 I just know the basics haha

@snder I'm mostly software . I know a lot of hardware theory because I'm a math guy but havent spent enough time actually building stuff outside of radio transmission lines and the such. So this is much needed real world expiernce for me.

@freemo Haha cool! It’s very nice you can combine the two! Maybe in the future when I have more to spend I’d like to build my own home kit and connect as much as possible

@snder Home automation was one of my early motivations that got me into simple EE (like arduino digital stuff low frequency)... Sadly I never actually built anything useful in that field, but it did at least get me studying the theory.

@freemo Things look a bit different since my time. Last time I used a SWR meter, it was a lot more analogue than that:D So impressive!

@Nyoei Most SWR meters today are still that way. But as someone who loves things that are needlessly advanced I insist that change!
