Thomas Zehetbauer replied to Thomas Zehetbauer's discussion 3DR for ARHAB?
"Reading the code for the SiK modem I found that the 3DR applies (quite inefficient golay) error correction only to the packet payload and throws away any package not matching netid, length or crc. It may be reasonable to assume that kind of bad…"

I wonder if the 3DR module of APM 2.6 / 2.8 would be suitable for a high altitude balloon.arhab has been done using 300bps RTTY over a 10mW NTX2 transceiver at 433MHzwhat method, protocol, bitrate and error correction is 3DR/APM using?how much…
