There's no need to limit your connections to VARA FM gateway (and P2P) stations that are set up for 'NARROW' mode. VARA FM stations that are configured for 'WIDE' mode will automatically negotiate a connection with any calling station that is set for 'NARROW' mode, and complete the session at the best throughput possible for the slower station.

With the mismatch in speed settings, the negotiation phase at the beginning of the session is likely to take a bit longer, but not so much as to justify avoiding connections with that station.

So long as you're using the built-in sound card system on the FT-991A (which simply won't support full-throughput VARA FM WIDE connections), you should keep your VARA FM modem software configured for 'NARROW' mode (on the VARA FM Settings" screen), to minimize the negotation time when connecting to stations set for 'WIDE' mode.
