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:

• Open the transverter by removing the top cover ( 8  #2 imbus screws) 

• Set the red jumpers on base the following table:
   

Jumper setup for several type radio:
/LIST NOT COMPLETE!/

You can check the position of jumpers on following photos:
Drawings of attenuator/jumper unit here.

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

• 13.8V/5A  stabilized PS and cables.
• 4m antenna or linear amplifier
• If you ordered the transverter with separate 4m RX input, connect the RX antenna to the second N (RX)connector.
• Transverter SND output jack connect to linear PTT input ( +50V, 1A max) (red RCA)
• Radio SND( GND on TX, or open collector) output connect to transverter PTT input.( black RCA)
• IF cable(s) btn radio TVR IF output, radio RX input ( 50 Ohm BNC/RCA or similar type)
• Switch ON your radio and set it to transverter mode, select the IF frequency,  28MHz ( check radio documentation)
• Switch ON the transverter, set front page PWR knob left clockwise.
• The base noise on radio will increase.You can set the RX gain by RX potmeter on transverter unit if it necessary.
• Set your radio to CW mode and push the transmit button. The red TX led on transverter starts to lit.
• Give continous carrier and check the output PWR on transverter led bargraph. Set the frontpage PWR poti right clockwise.
• Set the transverter input potmeter( accross the top cover slots you can reach it easy) and set the output PWR just up to 30W.
• If the transverter used before with low IF level and now with high power IF input,( max 5W!) you need to set the TX potmeter on transverter
  unit. Set the input power attenuator to middle position and set TX potmeter just up to nominal output power on the bargraph.If the transverter used before with high power IF input, you need to check also the TX potmeter and you need to set it up to nominal output PWR.
• IF you using very low IF output level radios( IC7600,IC7700,FTDX 5000 or similar -20dBm IF output types) You need the jump ON the transverter IF preamplifier.Set every jumpers to ON position. If ready set the output power the nominal value by the described procedure.
• • If you using HIGH POWER (5w) IF output radio and 1x IF cable mode, dont forget switch ON the transverter, or disconnect the IF cable from radio.
    Use the ANT output when you want to use your radio on HF bands. If the PTT cable disconnected, or the TVTR is OFF and you transmit with your radio,
    the 5W output power can kill transverter IF amplifier! Don't forget to reduce the radio output power to 5W if you using the transverter!
