+1 for the assertion that a lot of people, TH-camrs, reviewers, etc. overlook receiver sensitivity. I hate it when handheld transceivers are only judged by their output power
since you have both, can you please show and compare the speed of the scanning of 540-650MHz between the models? this is one of the useful ranges of pro audio wireless systems i'm interested in before buying, also curious about waveform capture and how to get it from the device, is mSD card the only way? thanks.
When looking at attenuators: a 10dB attenuators absorb 90% of input power. 20dB = 99%, and 30dB = 99,9% If you want to look at your 100W radio signal, that's 90W+ and expensive. Alternatives are: reduce output to 10W (or less), OR use the mini whip antenna to pick up a sample from your antenna. Depending how close you are, you still need an attenuator - but not one rated for 100W.
Noob here, could the TinySA be used to monitor for burglars using jammers that are jamming WiFi or Cell frequencies against security devices (e.g. Wifi Cameras and security devices using cell for back-up)?
Great question. It could pick up the signals from the jammers, but it would be hard to differentiate and there's no way to alert to an issue. You could maybe get a baseline of what the normal spectrum shows and compare it to what you currently see during a suspected attack. Probably not the ideal tool for what you're trying to do, but could maybe work in a pinch. Can't say for sure as it's not something I've tested myself.
Pretty much any SMA antenna for handheld radios should do fine. Just pick one up for the frequency range you want. There's also some with wide band receive from diamond. The telescoping antenna it comes with isn't bad but telescoping antennas can break easily.
Such a good device my freind was being stalked by her ex she hired a private investigator refered to her by her lawyer he did a scan of of her house and found listening devices and tracking devices he instructed her to buy one of the sa ultra as cheap alternative to the high tech analyzer he uses .He said if there's some thing transmiting the sa ultra will pick it up an incredible piece of gadgetry I believe I was astounded the amount of frequencys it picks up wifi 4g 5g you name it surprised its legal actually could cause a lot of problems for police trying to conduct surveillance.
Great video bud, have you looked into reticulum? It basically replaced IPV4, it has a lot of potential but a small community and I think it could solve a lot of problems that meshtastic have and could create an insanely strong Adhoc network
The cheapest version is made by the original manufacturer at less than 150 bucks. even a few years ago a comparable instrument of that class with all that capability would have cost you 50000 plus.
Extreme beginner here, would something like this allow you to detect drones operating in the local area? I’m assuming you’d have to understand what frequency they run on to detect them?
It would depend on the frequency. Many of them run on 2.4GHz and 5.8GHz which happens to be the same frequency Wi-Fi is on so it would be hard to differentiate just using this tool alone

Something often overlooked unfortunately.
The info you put out is the best on TH-cam. Straight and to the point and very well explained. Keep it up!!
Appreciate the comment! More to come!
I have the TinySA and it has become invaluable for my lab. Yes the ultra would be nice but the original is very good and I will keep using mine.
Definitely great to have around! Nothing wrong with that at all, the original is still very useful!
Excited for the how-to videos. I don’t have any electrical or radio background but excited to learn how to fully utilize this thing.
I'll get some of those up soon!
Very interested in learning how to use the attenuators and measure power output/spurious emissions plus receiver sensitivity also.
Videos coming soon 🙂
Hi!
Why didn't you enter the attenuator correction in tinySA so that you could see the actual measured power?
Did you do a more detailed video on the TinySA Basic ?

Good to know. Thank you for the great detailed info.
Using the Tiny as generator, what output impedance does it have?
Should be 50 Ohms, the golden standard.

@@The_Comms_Channel Thanks for the quick reply. I haven't found any products that fit the bill at a reasonable price.
Sure thing! I know it's not always possible, but if you can, I would recommend avoiding the WiFi cams
Does the smallest one have headphome jack? Or just the expensive one
That is only a feature on the Ultra model. I believe you can open it up and solder a headphone jack on the basic model though
@ thanks
Sure thing! Just a heads up if you're thinking of getting one, the ones linked in video description have Black Friday deals going on at the moment.
@ thanks
Are there better antenna options if trying to spectrum analyze in the field? I think my main focus would be analyzing VHF and UHF

@@The_Comms_Channelthank you. I picked up an RH77CA and RFH10, they are working great!

I've looked at it briefly. May take a deeper dive at some point.
Even the basic TinyVNA models have the MicroSB port. It's disappointing that the base model TinySA does not.
They're both USB-C
What you expect for less than 50 bucks?
Is there an affordable version of this that isn't made in China?

@@The_Comms_Channel there is special drone software on the web that is used in Ukraine that is specifically written for the TinySA.
@@germanjohn5626 Interesting. What is it called?
That’s not a NanoVNA??
Nope, but very similar interface.
Mine is on the way. Ebay sucks and I regret dealing with them, again.
Gotta watch out for knockoffs from some sellers. SeeSii is one of the safe sellers recommended by the TinySA website.
