IC-V82, IC-U82, IC-2200H).
The GSV sentence is incompatible with them.
• If “GPS Select” is set to “Manual,” the transceiver
automatically sets the NMEA sentence, and
transmits it along with the manually entered
position data in “Manual Position.” (p. 9-24)
(GPS > GPS Set > Manual Position)
• Please note that if “GPS Auto TX” is set to any
other setting than “OFF,” the data is automatically
transmitted according to the set time. (p. 9-40)
(GPS > GPS Auto TX)
