ME2T-PRO Connection and operating instructions
Front Panel controls:
Switch „ON” Provides power to the transverter, The „ON” LED indicator should light
PWR Output power control
ON LED Indicates ON status of the equipment.
RX LED Indicates the receiving status of transverter.
TX LED Lights when the transverter is on transmit position (PTT input is on GND)
LED Bargraph Indicates the relative RF output power of transverter.

Rear Panel connections:
ANT (UHF ) An „N” type connector is provided for 144MHz RF input & output.
PTT (RCA) This connector provides a connection to the TCVR send line. A ground
on this line places the transverter into transmit mode.(+13.8V/40mA)
IF in (BNC) Apply 28MHz drive to this connector. The input level is -10…+37dBm,
You can set the attenuator with jumpers.
On case single IF cable mode connector is common IF TX/RX.
IF out (BNC) IF (receive) output is available at this connector. Do not apply RF
power to this connector!
On case single IF cable mode this connector is open.
SND out (RCA) Send open collector output to external PA’s( 50V/200mA max)
DC SUPPLY Conn DC connector, 20A type.
Cable connections:
Two IF cable connecting on case low or high power(max. 5W) out TCVR’s

Using transverter with high power radio(100w) is your own risk,
NEVER use higher IF in power than 5W! Another case you will lost the warranty.
Setting of 28MHz input level:
1. Set the PWR knob to right full clockwise.
2. TX cw mode set the IF poti over the top cover slots- just up to full scale(30W) on the led
bargraph.
3. You can set the output power with the PWR poti from appr. 5W to 30W output.
