What do you mean? This is running on 433MHz, which is within the 70cm amateur band (420-450mhz)
- edoo 8y agoOh, 433.92 is only ISM in EU/Africa.
- ihuman 8y agoI didn't know that. I'm not too familiar with amateur radio around the world. I know people were able to contact other people around the world, so I assumed the bands were similar.
- macintux 8y agoMost long-distance communications happen in the high frequency bands (3-30 MHz) due to its different propagation characteristics. I haven’t researched the global commonalities, but I’d wager there’s more consistency in HF than the higher frequencies (VHF, UHF).
