but will they combust?

NVIS propagation

Is a interesting topic, basically what i am looking for. Problem being is that right now i am restricted to license free bands.

27mhz can skip if the conditions are right, im guess i just find out if it works. Used some web SDR to check the CB band round here…not much going on so at least there wont be much background noise

Thank you very much for the answer! The power difference between the 0.25W Lora and the 4W FM is huge yes, thats why i kinda hoped Thor over CB would give me better range in a environment where line of sight is not given and there isnt a Mesh network in place for the LoRa.

I am trying to make a low speed text chat connection at a distance of 20-40km, with half a city between the Radios. I looked into LoRa based standalone devices like the T-Deck, but what i saw online was sobering regarding the actual functionality out in the field(besides super duper ranges in elevated line of sight).

The next idea was just geting a cheap used CB-Radio and hooking it up to AndFLmsg, would that be realistic to clear the distance of 20-40km with half a city between it?

I mean if that dosent work out there is still the non licensed sub 9khz band…
