THnaks for that..I was wondering how to get rid of it!

Nice.. I have a Nooelec SDR radio here and am using the same software (SDR++) I used to use HDSDR, but dit not like it. I will try AirSpy and see if I like it. Thank you for sharing and keep posting. You will get more and more users!

I'm still learning ..it's my first but already love it!

These are likely not LORA signals. The same frequencies are used by millions of short range (low power) devices.

Yes, there lots of other signals in the band..the LoRA ones have a zig-zag patern inside..it can be easily seen

This tutorial is really nice, however I am a little bit confused we couldn't see LoRa up and down chirps here. Can you please understand me in the comment section?

First check if you are at the right frequency..868MHz for Europe, 915MHz for State..google for your country allowed TX/RX band..also, rise the receiver gain...and check the antenna..

@@viocaia Thank you so much, I am in Italy so it comes in the range of 868 MhZ. I found a chunk of chirps in the down screen, but it seems invisible. Now searching for an option to slow down and zoom in the down section of the software then perhaps I will be able to see them. Thank you so much

Any time

Can this SDR measure the true gain and tuned frequency of helium antenna? If not what would you suggest?

I don't know..but I can see at least which is better.I will send a steady 868Mhz signal from 20m via Nanovna and I can see how much each antenna can receive..probably, checking the numbers I can find the gain too..will see.Most important is to find if the antenna is tuned..BTW check Sorin channel about this..he is got a lot of experiments too.. kzread.info

THe best for measuring and tuning tuning antenna is a nanovna..like this kzread.info/dash/bejne/pGl9mI9tm5eWYdI.html

@@viocaia Yes.... Looking at all the Amazon eBay junk who knows what your getting..... I'm trying to see if on frequency and get true gain output on miner to test what works best for my area.... Loved to see radiated pattern....... I have seen 12" to about 36" 8 dbi antenna and wonder if the lobes differ?
