  • How to check the S.W.R. of your Antenna :
    ​Connect to "TX" on Radio output  and Antenna  to "ANT".  Proper adaptor/cable is required if your device has different type of connectors.

  1. Measurement V.S.W.R. : (see Pic.1)

  2. SW-102 TX connect Radio RF out  

  3. Radio TX , SW-102 with display S.W.R. measure data.
    Do not affect the test in the following cases, there are objects nearby, placed horizontally.

  • How to check the output Watt of your transceiver :
    Connect to "TX" on Radio output and dummy Load to "ANT".  Proper adaptor/cable is required if your device has different type of connectors.

  1. Measurement Power: (see Pic.2)

  2. SW-102 TX connect Radio RF out  

  3. SW-102 ANT connect 50 ohm Dummy Load

  4. Push Radio TX , SW-102 display is Power  measure data.
    (SW-102 is not for DMR system)

  • How to display rotate : (ver 2.02only )

  1. Press Yellow key to rotate display in 180 degree , 

  2. Press Yellow key to normal .
