The current delay of 30uS is too short to recover any carrier.
In the lmedm04 driver delays were added to overcome carrier lock
problems. The typical delay was 30mS (2 x 15ms register write
0x2c and read 0x24).
Other drivers that use STV0288 don't appear to have any delay are
likely to have also suffered this problem.
