Hello EriK, Thank you for the reply, and thank you also for those very helpful comments about the SI4432 modules. I have ordered the filter elements from the Ebay site that you pointed me to.

Will investigate how to do an installer -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Hi Erik, Tried it with the updated new file but no luck. When i zip the file my Norton refuses it and tries to erase the file. I repair the quarantine and zip the file in a new D:/SA directory. When I

For a 868MHz IF you would need? a LO module with 1736MHz maximum frequency in order to be able to exploit the whole range. You could use the SI4432 with a 868MHz IF but as its maximum output

Have you given any thought to a version with 868MHz IF? As thats also a common ISM band and filters for that are available.

I found a bug causing the tinySA SW to crash on certain PC configurations during startup The bug is solved in the updated SA.zip file in the files areas -- HBTE Files section:

YES, same here. If anyone figures out how, please post. I don't want to buy the $300 software to run a $35 device... Have tried downloading two .dll files it needed, installing free VisualStudio,

Hello Erik, Much appreciation for your project !! Would like to give it a try. I cannot start SA.EXE. I have unzipped the file. I have the C++ redistributable installed. When i double click SA.exe

Adding a 110MHz low pass filter at the input (almost) solved the problem Here is the FM band using a small antenna Still a bit of a hump below 90MHz -- HBTE Files section:

Extended build instructions uploaded including schematics and a picture of the filter -- HBTE Files section: /g/HBTE/files Erik, PD0EK

I think this is the filter to be used: Epcos B39431-B3555-U310-M1498 You can find the filter on ebay. A seller from Poland has a lot? (and you can find a seller that sells two for an exorbitant

Hi Tony, Filter: You probably have to build the 434MHz filter. The SAW filters are very cheap as these are used in remote control devices EBay

Hi there, I would very much like to build and experiment with this exciting project and I have established that I can get all the bits needed to do it - except one. I have not found a filter module

Jerry thanks for the inputs.The subject of antenna is really a wide field ,I should have narrowed my requesr for inputs. 1)My interest is only in 40 meter band.Its the band for Philippine hams.The

Ah, yes. Will correct -- HBTE Files section: /g/HBTE/files Erik, PD0EK

Hi Erik, Re. the build instructions. Connect the receiver module to D1 and the LO module to D5 of the Arduino (WARNING: Yo u MUST use a 3.3V compatible Arduino) Should that be 'Connect the receiver

And here is an example where the tinySA fails miserably Sweeping the signal from a small antenna between 0 and 200MHz The DAB transmission at 190MHz is recognizable but the FM band around 84MHz is

When trying to measure the spurs of a SI5351 the first measurement caused some doubt on the performance of the tinySA. Is the output of the SI5351 really that bad? The output of the SI5351 is

The CC1101 has the same problem as the SI4462. Its has a banded design so you can not sweep over a broad frequency range. The nrf24l01 is limited in dynamic range (only above -60dBm) and frequency

Awesome to see someomeone building this. I have had the the? about using a cc1101 transceiver module as a logarithmic detector and even have some hardware built, but I had problems with the software.
