Re: Arduino based component tester
I was late to the party, also. Discovered these about a year ago. I have two that seem to work well. The first one is a circuit board with a thin glass monochrome LCD green backlit graphic display.

Thank you! I had TFT_eSPI, WebSocketsServer and ESPAsyncWebServer installed. But not those others. Now it compiles :) "Sketch uses 500717 bytes (38%) of program storage space. Maximum is 1310720

Re: Version 2.8 of the WA2FZW/M0WID software for the ESP32/ILI9341 hardware is available
Hello Ismo, you need to install these libraries into your Arduino IDE: - TFT_eSPI ¡ú Library Manager - AsyncTCP.h ¡ú https://github.com/me-no-dev/AsyncTCP - ESPAsyncWebServer.h ¡ú

Re: Noise floor at low frequencies for TinySA with Arduino Zero
Thanks a lot Dave and Erik for your hints.Very helpful! I'll measure the bandwith of my BPF. Lets see if I can lower the noise floor by optimicing the BPF or changing the IF frequency

Re: Noise floor at low frequencies for TinySA with Arduino Zero
One reason is the?AGC acts by reducing the LNA as long as there is signal through the BPF. YOur BPF seems to be 1.4MHz wide (see steep step at 0.7MHz Second is the phase noise from the SI4432 that

Re: Noise floor at low frequencies for TinySA with Arduino Zero
Hi Piotr In my homebrew analyser based on an ESP32 processor I see a similar effect.? It is because at low frequencies there is very little difference between the LO frequency and the RX frequency,

Noise floor at low frequencies for TinySA with Arduino Zero
Hello, when sweeping from 0 - 10MHz (without an input signal) I always get a higher noise floor starting @ 0Hz - 2MHz. Does anyone has an idea what could be the reason and can this eventually be

Re: Small Dummy Load
Yes the larger CPU heat sink I used was around ?9 off ebay, it's very effective, the heat difference throughout the heat sink is minimal really. Don't need a fan on it unless I run 70+ watts

Re: Small Dummy Load
Very desirable to flatten the base of the resistor and the Al block, very few commercial parts are really flat. A sheet of 1200 wet and dry will reveal how flat the surfaces are. Tape the abrasive to

Re: Small Dummy Load
I'm not sure about the physics but amplifiers often use copper "heat spreaders" between the active devices and the aluminmum heat sink.
