I would say you need about the same power level as for voice over FM. Probably Rattlegram can cleanly decode data under some marginal signal level that would make voice difficult to understand. But signal to noise in FM does not linearly follow S/N on raw rf spectrum. The gain would be low. In any case, the strong point of Ribbit is not long range. You can outperform it with ft8 or wspr. The key in Ribbit / Rattle is leveraging all the available bandwidth in a voice FM radio (or ssb), even with acoustic coupling, plus the error correction capabilities due to FEC.</span></div><div dir="ltr" data-setdir="false"><span><br></span></div><div dir="ltr" data-setdir="false"><span>I think Rattle is a great app. If it is further developed it would provide many posible uses, in a way of improved APRS. I am myself trying the linux modem software and find it great too.</span></div><div dir="ltr" data-setdir="false"><span><br></span></div><div dir="ltr" data-setdir="false"><span>regards from Ricardo EA4GMZ<br></span></div><div><br></div>
