Re: ADE25MH Mixer - warning #tinysa
Dave, I bought 5 ADE-25MH from huyai-components on Sept. 22, 2019 @ EUR 4.29 and they work fine. Tried 2 of them so far: one working in the TinySA and one in a modified SPECAN. -- Joerg, ex-DB2OO

The mixers that you got, were those from huayi-components seller on ebay?

ADE25MH Mixer - warning #tinysa
Hi group I have finally got round to building the Tiny-SA this week. My version uses B3555 filters, kindly supplied by Tony G4WIF, and I am using an ESP32 as the processor (another processor with

Re: TinySA attenuator
Joerg, You have to ensure the inductors can not "see" each other otherwise the magnetic fields will destroy the stopband. At least put consecutive inductors on 90 degrees angle The SMD capacitors

Re: TinySA attenuator
I have built a 9th order Bessel 300MHz lowpass, according to the parameters from https://rf-tools.com/lc-filter/. ( https://rf-tools.com/lc-filter/ ) I set the minimum capacity to 2.2pF and minimum

Re: Log output of tinySA
As the code it multi threaded things get "out of order" in the logging. The logging is wrong, should be {} -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Re: TinySA attenuator
It should be at the front. The 350MHz filter has not been tested, its an elliptical filter and maybe too critical in component values. -- HBTE Files section: /g/HBTE/files Erik, PD0EK

TinySA attenuator
Erik, You originally put the attenuator at the very front end.? Your latest schematic shows it after the low pass filter. Which do you reccommend? Also, I see you redesigned the filter for 350MHz?

Re: Log output of tinySA
I'm pretty far along with the Jan 17 tinySA.ino file. Will probably stick with it unless there's a significant reason to go with newer code. Hope to eventually be using the native RPi display, not the

Re: Log output of tinySA
Erik, If that is not from the Jan 17 tinySA.ino currently in the files section, could you post the code it corresponds to? Though I may have all I need if the Jan 17 tinySA.ino file? was working well

Re: Improved display for tinySA
Erik, I really appreciate, that you seem to read my mind: I am eagerly looking for the code for the ILI9341 user interface. I have two of those: one with parallel interface and the other with SPI

Erik, I did find your list, it was a big help in getting a handle on tinySA.ino Have you verified that the current MSWindows package does not use any commands other than listed? Better yet, could you

Re: Improved display for tinySA
Looks good! That 2.8" screen makes it a good complement to a nanoVNA. And the nanoVNA is certainly popular. Though the the newer nanoVNA versions are going to a bigger screen. I'd prefer to have both

Improved display for tinySA
The first display was really tiny, the TFT 2.8" ILI9341 with touch is still cheap but more eye friendly and not too difficult to interface. With the touch I can drop the rotary and have a clean setup.

Re: TinySA and phase noise. Understanding the limitations of the SI4432 #spectrum_analyzer
Don't know a lot about the Si4432, but on the Si5351 these can improve spurs and noise: Shut down the other two outputs or there will be crosstalk. Load the single remaining output lightly,
