CONFIDENTIAL AND PROPRIETARY TO NORTHERN AIRBORNE TECHNOLOGY LTD.

1.2.5 The U513 replacement PLL device is switching the charge pump transistor Q506 incorrectly.

1.2.6 The frequency reference input level for the U513 replacement part is

below the manufacturers recommended operating level.

1.3 Description

This modification consists of modifying the RF buffer amplifier and the PLL replacement device as follows: 1.3.1 The RF buffer amplifier modification consists of:

a) Removing capacitors C601, C652, resistor R569, RF buffer amplifier U512.

b) Bypassing the obsolete amplifier U512 by installing a 22 AWG jumper

between pads 2 and 7 of the U512 footprint on the primary side of the NTX138-5 printed circuit board.

1.3.2 The PLL replacement device modification consists of:

a) Removing capacitors C600 and C605. b) Changing the component values of capacitors C591, C593, C594,

C595, C603, C604, inductors L517, L518, resistors R566, R567, R568, R570, R579, R639 and PLL U513.

c) Installing a capacitor C676 in parallel with R579. d) Changing the component value of capacitor C320 on the NTX138-2

Transmitter subassembly.

1.4 Compliance

Customer option. NAT recommends this change be accomplished only if the units require these parts to be replaced.

1.5 Approval

No change to existing approval.


Mar 19, 2007 Page 3 of 5 ENG-FORM: 603-0130.DOT


1.6 Costing

This modification incorporates a design improvement to circumvent the RF buffer amplifier SA5204A and PLL device MC14191F obsolescence and does not constitute changes to correct a malfunction. The modification is therefore not subject to warranty consideration. 1.6.1 Labour Three (3) hours estimated. Includes required test time. Not warranty reimbursable. 1.6.2 Parts Please contact Customer Service for current pricing.

1.7 Special Equipment Required

None.

1.8 Weight and Balance

No effect.

1.9 Electrical Load Data

No effect.

1.10 References

NTX Service Manual: SM28 Section 5, Maintenance. Section 6, Drawings.

1.11 Other Publications Affected

None. The next edition of the service manual will include the changes described in this bulletin.

2. Procedure Instructions

2.1 Modification Procedure

2.1.1 Refer to the NTX Service Manual SM28, Section 5 for details regarding transceiver disassembly and removal of the Transmitter and Receiver subassemblies.

2.1.2 Referencing the Component Locator drawings (NTX138-5\924-0, 924-1

and NTX138-2\924-1) do the following:

a) Remove and discard capacitors C600, C601, C605, C652, resistor R569 and RF buffer amplifier U512.

b) Replace capacitors C591, C593, C594, C595, C603, C604, inductors

L517, L518, resistors R566, R567, R568, R570, R579, R639 and PLL U513.

c) Install capacitor C676 in parallel with resistor R579 (on the same foot

print). d) Replace capacitor C320 on the NTX138-2 Transmitter subassembly.

2.1.3 Install a 22 AWG jumper between pads 2 and 7 of the U512 footprint on

the secondary (solder) side of the NTX138-5 printed circuit board. 2.1.4 Replace the subassemblies and reassemble the unit by reversing the

procedure referred to in section 2.1.1.

2.2 Testing Procedure

2.2.1 Refer to the SM28 Service Manual, Section 5, for the Receiver subassembly alignment procedure.

2.2.2 Refer to the SM28 Service Manual, Section 5, for the appropriate

complete performance tests.

2.3 Identification Procedure

Stamp an "X" (blacken out # 15) on the mod status tag to indicate MOD 15 has been incorporated.
