// Status=review FT4 is designed for contesting, particularly on the HF bands.
Compared with FT8 it is 3.5 dB less sensitive and requires 1.6 times
the bandwidth, but it offers the potential for twice the QSO rate.
FT4 is not recommended for everyday use.

Clicking *Best S+P* during an Rx cycle arms the program to examine all
CQ messages decoded at the end of the Rx sequence. The program will
select the best potential QSO partner (from a contesting perspective),
and treat it as if you had double-clicked on that line of decoded
text. Here "best potential QSO partner" means "New Multiplier" (1st
priority) or "New Call on Band" (2nd priority). "New Multiplier" is
currently interpreted to mean "New DXCC"; a more broadly defined
multiplier category (for the ARRL RTTY Roundup rules) will be
implemented in due course. We may provide additional priority
rankings, for example “New Grid on Band” (useful for North American
VHF contests), sorting by signal strength, etc.
*Best S+P* is a useful feature only if you have defined what "best" is
supposed to mean. This is done by configuring suitable options on the
*Settings | Colors* tab. Selection and ordering of color-highlighting
options determines what potential QSO partners will be chosen by the
"Best S+P" feature. Optimum choices will be different for different
contests. In a contest using RTTY Roundup rules we recommend
activating *My Call in message*, *New DXCC*, *New Call on Band*, *CQ
in message* and *Transmitted message*, reading from top to bottom.
