 Note - For Slot 1, NinoTNC tone frequency centre is 1500Hz for BPSK, 1700Hz for FSK.  Hence different dial freq.

 ARDOP can be decoded simultaneously with ''ardopf''. The slot 2 centre frequency - for ARDOP - is at a fixed 1500Hz offset. You need to run in limited bandwidth mode ARQBW 500MAX - maybe 1000 - need to test that.
+===== Note on software =====
+Please don't run Dire Wolf on HF - it lacks both ACKMODE - which is particularly problematic with longer transmit cycles since the node has no way to know when the modem is available to send - and also has no transmit bandwidth filtering - so will obliterate the other slots on transmit. We depend on good discipline to avoid interfering with each other in this very limited slice of bandwidth.
