D About 137 kHz band operation (Europe version only)
The 137 kHz band, between the 135.7 kHz to 137.8
kHz, operation in the CW mode is optionally available.
The RF signal from [X-VERTER] is used for the 137
kHz band operation, and an external amplifier unit is
necessary.
See the connection diagram below for reference.
