Vertex Standard FT-1000MP ユーザーズマニュアル

The following tables outline the 16-byte data record

structure common to the Operating Data, VFO-A, VFO-
B and Memory Data records. The table below shows
assignments for each of the 16-bytes in the Operating
Data Record.

Band Selection - The 0.1~30 MHz transceiver op-

erating range is divided into 28 bands, represented in
hexadecimal format in the table below. Data read in
this record after downloading is in binary format, and
must be converted to hexadecimal, then translated to
the corresponding band.

The Band Selection data byte is divided into two 4-

bit fields, representing the first and second value of
the band number hex code. The Bit 0 and Bit 1 of the
first field are used as flags for the memory mask and
scan skip feature. A bit value of “1” means enabled,
and “0” for disabled. Each value of the hex code is
entered into its respective field in 4-bit binary format.
The table below outlines the Data Byte field, and show
an example of how the 24.5 ~ 25.0 MHz band would
be read as:

Operating Frequency - Likewise, the current op-

erating frequency is similarly coded, this time into four
bytes comprised of eight fields, from MSB to LSB. For
example, a read binary value of 0000 0000 000 0101
0010 0100 0001 0000 is 14.250.00 MHz as follows:

Clarifier Offset - Clarifier offset is written using 16-

bit binary data in two bytes. Negative offsets are ex-
pressed in binary 2s-complement format, with a lead-
ing bit flag value* of “1.” Although frequency resolution
below 10 Hz cannot be viewed, absolute Clarifier off-
sets down to 0.625 Hz can be read from downloaded
data.

Arithmetic conversion must be done on the binary

value to arrive at the actual frequency offset (multiply-
ing the 16-bit binary offset by 0.625). For example, a
binary value of 0011 1110 0110 1111 (3E6FH or 15,983)
multiplied by 0.625 results in an offset of +9989.375
Hz.
