ME4T-PRO Setup before first operation

1.    We deliver your transverter by your request. Basically transverter is ready to use you need to connect it your radio and it run.

2.    If you have second hand transverter or you need to set to another type radio you follow the next instructions:

Position of built in attenuator jumpers

Low PWR IF input (-20..+27dBm)
2x IF cable connection

Low PWR IF input (-20..+27dBm)
1x IF cable connection

J1 ON

ON

J2 OFF ON
J3 OFF OFF
J4 OFF ON
J5 ON OFF(ON- 2nd RX)

High PWR IF input (27..+37dBm)
2x IF cable connection

High PWR IF input (27..+37dBm)
1x IF cable connection

J1 OFF

OFF

J2 ON ON
J3 ON ON
J4 OFF ON
J5 ON OFF(ON-2nd RX)

3. Connect to transverter the following cables, made/check the settings:

4. Cheking the measure pin levels.( Only for service)

Meas. pin

Level

Possible. failure

M1

0.4V  if < or 0 - RX LO level is low

M2

0.2V  if < or 0 - TX LO level is low

M3

0- +3dBm  if < LO level is low

M4

+13-15dBm  if < TCXO level is low

+12V

12-13.8V  if < 12V tvtr supply voltage is low

+12VTX

12-13.8V  if < or 0 Q1 or Q2 is failure

+8V

7.9-8.1V  if <7.8V IC2 stab is failure, ASL550 LO amp is failure

+8VTX

7.9-8.1V  if <7.8V IC3 stab is failure, ASL550 driver amplifier is failure
