As mentioned before, there are four opcodes that
cause the MARK-V FT-1000MP to report (update) its
operating status by downloading all or a portion of its
1,863 data bytes. These opcodes are shaded in the
CAT Commands table (pages 94 ~ 97).
Status Update (Opcode 10H) - The 1st and 4th
parameters of this command allow selecting different
portions of Status data to be returned, as follows ("X"
is the 1st parameter, "U" is the 4th):
Read Flags (Opcode FAH) -This command can be
set to retrieve all six Status Flag bytes, or else five bytes
- three Status Flag Bytes, plus two transceiver ID bytes.
The Status Flag Bytes are described on the preceding
page, and in the Record Tables on the previous page.
The transceiver ID bytes are used in programs to
distinguish the MARK-V FT-1000MP from other mod-
els, which have different, unique values returned in this
situation. The constant values of 03H and 93H are re-
turned by the MARK-V FT-1000MP (and only the
MARK-V FT-1000MP), as shown:

Read Meter Data (Opcode F7H) - Sending this com-
mand returns a digitized meter deflection indication,
between 00 and FFH (usually around F0H maximum).
Four copies of this value are returned, along with one
padding byte (F7H), as follows:

During reception, the signal strength deflection is
returned. During transmission, the parameter repre-
sented by the reading returned depends on the setting
of the METER switch.

This identifies the current or last-selected memory
channel 1 ~ 99, P1 ~ P5 or QMB 1 ~ 5 for operation.
The table below translates hexadecimal codes into
corresponding memory channel numbers. Please read

Important Note!
The Hex Memory Channel Codes for returned
memory data shown above (Byte 7) are different
than those used in upload command data
(opcodes)!
The memory channel hex codes used as argument
(parameter) bytes for opcodes are offset by one
(that is, one value greater) from their returned data
counterparts. Therefore the channel hex codes
used in opcodes 02H, 03H, and 0DH would range
from 01H ~ 71H.
When constructing command block bytes, ensure
that the correct memory channel hex code is used!
