Re: Homebrew spectral analyzer
Hello Gerard, I guess your issues, to get the Web Server running, are related to missing upload of the "data" subdirectory (under your sketch folder) into the SPIFFS file system on the ESP32. You will

Hello, thank you for your answer I¡¯m going to test this afternoon I thought it created a new Wi-Fi network and we had to connect to it, but in fact I understood that it¡¯s the opposite, it¡¯s ESP

Re: Homebrew spectral analyzer
Hi Gerard. You are making good progress, well done. I have not had chance to look into the SPIFFS.begin() issue.? I guess the ESP32 libraries have been updated and the function now works in a

*Hello* *i need some help to put the software in thr ESP:* Tell me if this is good or if I comment a mistake. I think we first have to decompress the SimpleSA_011.zip file Then do we need to do

Hello Erik, Thank's for the retur i will look that I¡¯m only at the beginning of my tests For now nothing uploaded in ESP It is seen in the WIFI network, it is already a good point I have to go back

Re: Homebrew spectral analyzer
The simplest first test is if you can see the zero Hz peak. E .g. If the RX module can see the output of the LO as it leaks through the mixer. -- HBTE Files section: /g/HBTE/files

Hello, thank's for your answer For now I have not yet received the IL screen. I have another screen but I believe based on XT2046, I do not know if it can work. Unless I try a Wi-Fi connection with

Re: Homebrew spectral analyzer
I think the best test is to try the signal generator and the tracking generator in signal generator mode. Connect the sa connection on the simpleSa to your oscilloscope ideally with a 50 ohm

Re: Homebrew spectral analyzer
Hello, My PCB is practically completely wired. I have a nanovna, a 200mhz 4-way oscilloscope, a 60MHz FY6900 generator. My question is how to test the differents modules depending on the sch¨¦matic. I

I didn't go further. The current status is HF, and there is still a resonance point of - 80dbm. LF can be used, but I can see a frequency point of 215MHz occasionally. However, when I move the LCD
