I was sent to a page I could not read; that page sent me to another page I could not red. ?I think it is in Erik's native language. ?Could someone smarter than I verify I was at the correct place.

There is not an internal IF counter,? so you may use only the marker. TinySa? it's the smallest semi-professional spectrum analyzer, I have R&S and HP on my lab also, but for a lot of purposes it's

While I may not purchase a larger format SA in the future, I would gladly donate for the developement of one by way of a thank you for the hard work, determination and support we as a community have

Thanks for the info and reminder! I finally made a donation. Roy WA0YMH wrote:

If you want to support Eric's work go to tinysa.org at the end of the first page is an instruction on how you can donate.

I as well! larry

Yes, it's the helium network and understood Erik. Many thanks for all the help and explanations.

LoRa is using spread spectrum technology. The signal is below the noise floor as the SNR can be negative. You can not use a SA to see normal LoRa signals. Only when very close to the transmitter --

For OTA LoRaWAN indeed needs that. But OTA isn't always possible for example for a GPS tracker (you don't know if you are in range of a LoRaWAN Gateway and just want to send your package through ABP)

your balcony window. On the outside, of course, would be best but on the inside if necessary. Other windows are to be chosen in descending order of size and then of elevation. +++++

Don’t know if it helps, but this is the information I get when I see another gateway:

Many thanks for all the input. I’m trying to detect LoRa signal (868mhz), there are specific products do do this ( https://lora-alliance.org/lora_products/field-test-device/ ). As I understand it

is a dead carrier, very well. However, if it is a chirp from a device, then it will not be seen. spread across the chirp; those are, after all, the whole idea of the protocol. In addition, of course,

Yes, that is what is being said. If the signal is below the noise floor, you will be unable to detect the signal. Spectrum analyzers in general, including some expensive units, typically exhibit a

Thanks Erik, I’ve tried three different antennas with the same result. This is what I’m seeing: When you say input noise floor, are you saying the signal may just not be strong enough to pick up?

Suggest to disconnect and reconnect the antenna. If nothing changes you may be only seeing noise and no signal Remember the tinySA is not a receiver so the input noise floor is higher then a receiver

Is the signal still there is you completely remove the antenna? If so, it may be a spur generated by the TinySA circuitry. Dave - W?LEV -- *Dave - W?LEV* *Just Let Darwin Work*

Hi, Just bought my tinysa so please excuse the basic questions or if I'm fundamentally misunderstanding something. I'm trying to find the best position indoors for a alora antenna (868Mhz) as I have
