Hello again, Just for update about the thread, I've disassembled the TinySA and remove the U22, the RF Switch, and replace it by 0R jumper joinning traces. The result is that the power values from

2 volts peak to peak is +10 dBm if you have a scope.

I've added a page to the wiki describing some steps for manual fault finding. Could some of the users that have (had) problems with their HW have a look at this page and check if it helps them

Thanks for the quick response!

Dear all, I've been playing with my TinySA, and I think I've passed the measure power limit during some test and now my device doesn't measure correctly. Probably I exceeded the +6 dBm. I've

This is a broken LNA Suggest to contact your supplier -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Tested with different coax cable but same result..

Got problem with self test and calibration.. any ideas?

everything should be fine with you, the older younger version is determined by the bootloader, it seems to me that there are almost no changes in the difference between the versions, the difference is

Hi Richard, I just purchased the 406 from R&L arrived today. Mine has the same marking. My confusion is that the upper right under Zeenko is ZS-405, but S/N is SU-406-xxxx H/WV0.4.6. So did "they"

I checked the cables and adapters, they are ok. I couldn't check the RF signal via oscilloscope, probably because the signal is too low. But the 30 MHz signal is coming out, I tested it with an

I've been trying to align some HT's this week. After a lot of messing about I concluded that some of the commonly available "ham"style meters were somewhat variable in quality. So I decided to try

Sorry it is -35 dBm for ultra and -26 for smaller version.

Well on mine the 30MHz fundamental is consistently at -35dBm. No problems with tests and all attenuator steps as well as the LNA do function as expected. TinySA Ultra (SeeSii) Version:

I don't know what "support page" you were on before but this is the only place where the developer Erik supports the tinySA products.? Read this post about failing self-tests before asking more

Hello, I am not sure if I am confused :) but something is telling me that that I did read it somewhere, but I can't find it in the tinySA Ulta menus. Is there a, or was there an option to upload a

Through the dedicated tinySA support page I was forwarded to the tinySA groups. I'm not sure whether hardware issues can be reported along this way. I'm owning a tinyAS ultra, S/N SU-23080463. Since
