Has anyone played around with this new Multipsk feature yet ?

> 3) Reed-Solomon identifier for automatic detection of the digital
mode and the frequency (automatic tuning).

> This identifier permits to, automatically, locate, any digital
transmission done in one of the RX/TX modes handled by Multipsk (91
modes and sub-modes in 4.1.1 version). It is detected, in one hand,
the used mode and, in the other hand, the central frequency of the
identifier (which is also the central frequency of the transmission),
with a precision of +/- 2.7 Hz. As soon as this identifier is
received, Multipsk switches on the received mode and frequency and
decodes immediatly the QSO in progress or the call (CQ). This
identifier is transmitted in 1.4 sec and has a bandwidth of 172 Hz.
Its detection is done down to a Signal to Noise ratio of -14 dB
(without missing at -12 dB), so with a sensitivity equal or better
than the one of the majority of the digital modes (RTTY, PSK31...).
