    Why is it that those who know least about radio consider that it is ok to vomit all over the electromagnetic spectrum, just because they cannot see an immediate problem?

    I did not say I don't care. I said what the prevailing attitude is someplace :D

    Fortunately, with new technologies such as spread spectrum (CDMA), they have an inherent resistance to jamming, or operation in a noisy spectrum. But yeah, spewing across the EM band is still bothersome.

    This thread started with a question about 434 vs 868MHz antennas and still is not resolved (see my prior post).
    Why some who feel disagreement about something find it ok to vomit over a thread with unrelated content is beyond my understanding.

    The only way to know if something will work, is to try it and see.

    But I would tend to try the HC-12 modules, and proper aerials, and see how that works - it's a cheap and easy solution.

    Hi, ok good idea too, thank you. I do have enough HC12 modules to experiment with in this project as well as try to set one up in a repeater role.
    Two RFM95 modules I have will be used in a LORA test; I will let you know the results. It may be several months to get to that because this is when time is available.
