Hello all, I was wondering if anyone could offer some insights about the true upper limits of the frequency bands that the TinySA Ultra ZS-407 can detect. And what the corresponding signal drop-offs

To my knowledge there are today (May 12, 2025) no clones of the Ultra+ models. -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Hi, I think I'll chime in with my Banggood experience. I did not know about this group when I bought it, or the concerns about copies and clones were so bad. It also did not come with a stylus. I

Very interesting. Please let me know which settings have you used, as I have a similar problem in 6m band. It's a wide-band QRM. It's impulsive and is also present as well.

This is how looks tinysa ultra + from banggood. I dont have any calibrated signal generator to test how to measures. Seller says its genuine, i dont think so, there was no pen stylus inside.

i go to buy an Raspberry, for test you're tool, i'm beginner in those domains, i think "tsactl" have a great potentiel ! i come back to tell you. Thank you and all the team for you're help

Hi Erik, understood, many thanks for your fast answer and have a nice Sunday. Seb.

Judging from the picture the signal level is just on the edge of a rather arbitrary boundary condition I've defined. You can safely ignore this. Will adjust the value in a future FW release. --

Hi there! I recently bought an ZS-407 (HW 0.5.4, FW -197) from Eleshop and just wanted to ask if it is a non-issue when the Self-Test is fine, but the "Level Cal" says "Signal Level Incorrect" (-> but

If it's any help, QtTinySA can save trace data continuously to a PC (including Pi) and does it as fast as the tinySA can scan. The Wiki describes how it works:

The tinySA never will be able to realtime record the real input signal. It is not an SDR -- Designer of the tinySA For more info go to https://tinysa.org/wiki

Michael, Strange behavior. Normally, the switch on the left is on the OFF position and the switch on the right is on the ON position. Regardless of whether the USB is plugged into a computer or 5V DC

Thanks you for you're reply, you confirm me the Tiny SA Ultra+ can't record the integrality of the realtime signal on his sdcard, and need external recorder ? What sort of model of rasberry pi is

Thanks for the quick reply and I'm glad it's an original. As I plan to buy some more I had to be sure that they are not copies. With the firmware it was stupidity on my part because I thought the

Eleshop for sure does NOT sell clones. Did the FW version number change? If not, you may have loaded the FW in the wrong direction (into your PC) or you have a problem with a USB 3 port Download the
