    Sometimes, if the power is low and and range is limited (effective radiated power), certain frequencies may be allowed even if they overlap other licensed frequencies.

    I guess the thing is, the Recco receiver works because it has a large antenna and lots of power. But the frequency used actually has very good range at very low power.

    I hear you. Something needs to hold it in place securely. That's probably the best there is right now.

    That's relevant. It just goes to show that more than one mode can be combined for effective search.
