Avoid the pins on the nano that double as uart pins -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Erik, I have the 'Blue Pill' and the Nano (I bought both) but plan on using the Nano for my first build. Is the Nano what you're using, or what Arduino did you use for your build and was there any

If you use an Arduino with actual serial interface you may have to choose other pins -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Daniel. From what I read of Erik's Build Instructions, here's what connects to the Arduino (Nano or otherwise - not sure about the 'Blue Pill' version): *Pin? ? Note* 6? ? ? ?SDO Connect to D3

May I suggest you change the footprint for the impedance matching around AND between the SAW filters to CLC Pi configuration? Impedance matching between the two SAW filters can give significant

I have attached my version of the schematic diagram . To get to the PCB stage I have to have the correct connections with the controller. Is anyone kind enough to tell me which pins connect LO and RX

Ahh ha! Yes I am using a temporary sub-standard one SAW filter. I will be improving that, thank you Erik. 73, Gary WB6OGD

Looks like the image created inside the SI4432 due to insufficient selectivity of the SAW BPF. What SAW filters are you using? I did a post some time ago on this issue -- HBTE Files section:

You guys are a lot smarter than me, but, I have been seeing something that I can't understand, but maybe this is the AGC action that Dave is seeing. When looking at my AD9851 (DDS-60 kit) I always

Erik / Karl, Thanks VERY MUCH for the link and latest info - - I hope to have my TinySA running when I get all the parts in hand tomorrow. Right now I have the transceiver boards, the mixer, and the

It's here: https://github.com/erikkaashoek/tinySA

Search GitHub for tinySA -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Interesting indeed. Some more pictures. First with x69 = 60, agc enabled And with the gain fixed: Perhaps some explanation - the response of? my SAW filters as measured with a NanoVNA: I tried with

Erik, Where's the location of the Github repository so I can fetch the update? Please let me know - and THANKS VERY MUCH? - This is a great project..! 73 de Marty, KN0CK

I pushed update code to github Rather dirty but the il9341 works, including touch so can function as a fully standalone spectrum analyzer now -- HBTE Files section: /g/HBTE/files

Hi Erik, Is the .ino file for the larger display available for evaluation? I have purchased all the parts including the ILI9341 display to build my TinySA and would like to try that code on my Nano,

Interesting, This is what I get with 0x69 set to 0x60 and a -5dBm and -30dBm signals and a 20dBm/div scale. As you can see my AGC acts much earlier. The AGC is multiplied by 4 before display Can you
