SERVICE BULLETIN LIST

DATE
INCORPORATED
Mar 30/01 Corrects for anomalous behavior observed during
power interrupts between 4 and 250ms duration.
SW Ver. 1.50; HW Mod 10.
Mar 30/01 Corrects for anomalous behavior observed during
testing at Airbus. Refer to EPRs 00001, 00002,
and 00003. SW Ver. 1.60; HW Mod 14.
Mar 30/01 Eliminates problems encountered with the existing
Controller D module, and provides more reliable
XK516D1 Transceiver operation. HW Mod 22.
Mar 30/01 Eliminates problems encountered with the
ON/OFF module, and provides more reliable
XK516D1 Transceiver operation. HW Mod 15.
Mar 30/01 Changes made in the upgraded software: Added
bit with Air/Ground status information to ARINC
429 Word Label 270 broadcast to ACARS MU and
Radio Control Panel. HFDL SW Mod 3.
Mar 30/01 Changes made in the upgraded software: Correct-
ed erroneous LRU Fault indication when Trans-
ceiver is in Data mode and on the ground, and the
Radio Control Panel input to the Radio is missing
or not available on both frequency select ports.
HFDL SW Mod 4.
Mar 30/01 Eliminates problems encountered with the existing
Receiver/Exciter module, and provides more reli-
able XK516D1 Transceiver operation. HW Mod 13.
Mar 30/01 Eliminates problems encountered during vibration
testing, and provides more reliable XK516D1
Transceiver operation. HW Mod 11.
Mar 30/01 Converting the HF Transceivers to the new Part
Numbers will correct potential HF system lockup
conditions, resulting from unreliable HF Transceiv-
er/Coupler control communications in installations
with high EMI conditions.
Mar 30/01 Corrects potential HF system lockup conditions,
resulting from unreliable HF Transceiver/Coupler
control communications in installations with high
EMI conditions. The software upgrade sets the co-
axial interface to Coupler, as the default, in the
Transceiver Control software. SW Ver. 1.70; HW
Mod 16.
Mar 30/01 Reduces potential HF Transceiver susceptibility to
false PTT activation caused by keying of other au-
dio components. HW Mod 18.
Mar 30/01 Corrects for spurious signals on SELCAL output
caused by ringing in SELCAL output stage. Cor-
rects for intermodulation distortion in the RF spec-
trum in the internal HFDL data mode. HW Mod 19.
