Technical data printout on the
Journal
0: Disabled
1: Enabled
1: Instead of the personal name, the following data
are listed on the Journal for each G3
communication.
e.g. 0000 (1) // 32 (2) V34 (3) // 288 (4) // 264 (5) // L0100 (6) 03 (7) 04 (8)
(1): EQM value (Line quality data). A larger number means more errors.
(2): Symbol rate (V.34 only)
(3): Final modem type used
(4): Starting data rate (for example, 288 means 28.8 kbps)
(5): Final data rate
(6): Rx revel (refer to the note after this table for how to read the rx level)
(7): Total number of error lines that occurred during non-ECM reception.
(8): Total number of burst error lines that occurred during non-ECM reception.
ƒ EQM and rx level are fixed at “FFFF” in tx mode.
ƒ The seventh and eighth numbers are fixed at “00” for transmission records
and ECM reception records.

Rx level calculation
Example: 0000 // 32 V34 // 288/264 // L 01 00 03 04
The four-digit hexadecimal value (N) after “L” indicates the rx level.
The high byte is given first, followed by the low byte. Divide the decimal value of N
by -16 to get the rx level.
In the above example, the decimal value of N (= 0100 [H]) is 256.
So, the actual rx level is 256/-16 = -16 dB
3 Not used Do not change this setting.

Line error mark print
0: OFF, 1: ON (print)
When "1" is selected, a line error mark is printed
on the printout if a line error occurs during
reception.
