Try using
MODEM 300 7 at 30
This will set up a number of modem frequency groups that'll help with
(mis)tuning:
Channel 0: 300 baud, AFSK 1600 & 1800 Hz, D, 48000 sample rate
0.0: D 1510 & 1710
0.1: D 1540 & 1740
0.2: D 1570 & 1770
0.3: D 1600 & 1800
0.4: D 1630 & 1830
0.5: D 1660 & 1860
0.6: D 1690 & 1890
Fairly unlikely I'll get anything here on Perth on 40m on packet with my
antenna but I'm curious on the performance of Direwolf on HF so I'll
have my station listening for a few days.
