I think what you are seeing and hearing, is locally generated. The 'swooshing' noise you are hearing is due to the sweep rate of your TinySA. If you change the sweep rate or reduce the frequency range you are viewing, and if you vary the sweep rate, it may become more obvious what the signal actually is, and where it is coming from. When listening, you should tune directly to the signal centre frequency and use zero span. I assume you are using the supplied mall whip antenna, in which case you may actually be picking up some interference from the TinySA itself. However, it is more likely that it is emanating from an electronic item somewhere around you or your immediate neighbour's homes. Allocations vary from country to country, but these sorts of frequencies are used by short range radio control devices, and for industrial purposes such as collecting telemetry from remote power and water installations, or the control of temporary traffic lights etc. Regards, Martin |
Need expert opinion - signal pattern

Using the tinySA Ultra, I've observed a cycle that repeats itself continuously – a short 454 MHz signal followed by very short flickering bursts at 460 MHz (see first video link): I used listen mode and recorded the audio of the longer 454 MHz signals which sounds like a repetitive whoosh or pulse (see second link for audio): Note LNA is OFF. These are actual dBm readings which have been as high as -50 by our north wall. Could this be UWB radar similar to that used by military and law enforcement to create visual representations of any people behind walls in non-metal structures? All opinions about what the signal pattern might be are appreciated. |
Re: Official Re-sellers?
I second R&L. They are a USA vendor with a very good reputation. Support your local vendors!

Re: Official Re-sellers?
Yep.? I just ordered an Ultra from AliExpress using the link on the tinySA.org website. Paid via Paypal.? Ordered a couple of appropriate attenuators as well.? I've ordered other similar items from AliExpress in the past and it was all good.? Usually took ~2wks to get stuff.?

Hello All, |
Official Re-sellers?
Hello All,
I am interested in purchasing one of the Tiny SA Ultra units.? Can somebody direct me toward an official re-seller(s) of the unit either in or can ship to the USA.? I do not want a clone. Also, what is the latest update for the original Tiny SA (genuine) that can be loaded with a Windows machine? Thank you. --jeff |

For intermod calculations, I'm using EazyRF Ok then you should know that the the "import markers" feature from QtTinySA reads Winradio marker file format. EazyRF is able to export markers to that format, meaning you can export your complete list of frequencies to QtTinySA? !!? ;-)? ? |

Re: UHF Frequency Monitoring on PC software for tiny sa ultra
If you want to be able to calculate custom set of intermodulation-free carrier frequencies for your mics and take into account the scan, you're probably looking for a RF microphone coordination software, where you can import the scans from these tinySA's scanning softwares. I don't think you can have these two things in one software for now. Regarding the monitoring of these frequencies, QtTinySA recent updates made significant improvments for RF mic surveillance purposes. Custom markers give you visual and quick access to the frequencies you want to monitor. |

开云体育Thank-you for your response.? And will the unit work with Linux OS ? ? Kind regards, Jonathan Burns ? ? From: [email protected] <[email protected]> On Behalf Of Erik Kaashoek ? The current tinySA Ultra uses harmonic mode above 5.3GHz. This reduces sensitivity a bit but the ability to detect transmissions has been demonstrated up to and above 10 GHz Designer of the tinySA |
Re: FW: TinySA Ultra enquiry
The current tinySA Ultra uses harmonic mode above 5.3GHz. This reduces sensitivity a bit but the ability to detect transmissions has been demonstrated up to and above 10 GHz
So no need to wait for updates to display 6.2GHz transmissions -- Designer of the tinySA For more info go to https://tinysa.org/wiki/ |

Sent: 07 March 2024 15:48 To: '[email protected]' <[email protected]> Subject: TinySA Ultra enquiry ? Dear Sirs, ? I am very interested in purchasing the latest TinySA Ultra model from your Mirfield (UK) reseller and wish to know whether the unit has forward adaptability to receive updates to expand the top end of its range above the current 5.96GHz. ? I have in mind the imminent projected expansion of the latest 5G wi-fi mid-band to 6.2GHz. ? I think I read on your site that the unit will operate / synchronize with Linux distros as well as the typical OS systems for data transfer.? Am I correct? ? Thank-you in anticipation. ?
