Product Information
  • Overview
The MyDEL Surecom SF-401 Plus reads your RF transmitted frequency from 100 to 3000 MHz (27 to 100 MHz coverage with reduced specs.).

Additionally, it can read and display your CTCSS tone and DCS code on the backlit color LCD screen. 
Display may be set to read 0.000 or 0.0000 MHz. With TCXO and charging LED.
Auto-power-off may be set for 1 to 9 minutes. Built-in 3.7 Volt Li-ion battery.

This items comes with: BNC antenna, USB charging cable and UK 3 pin USB power supply.
A comprehensive instruction sheet is also supplied.

  • This frequency meter is capable of measuring the parameters of the frequency of the continuous carrier signal, with signal strength indicator. 
  • This portable frequency counter is designed for counting continuous wave signals coming from radios. 
  • There are easy ranges for you to choose. The ranges cover most of the frequency of the two way radios you want to measure. 
  • Its four-button control is easy to use and its small size allows you to carry it anywhere you like.
  •  Work by  TCXO(Temperature Compensate X'tal (crystal) Oscillator) ,In the range of -45 ℃ ~ 65 ℃ can reach ± 2 ~ ± 4ppm accuracy
  • This includes areas such as 2m HAM radio, all VHF and UHF
  • DMR Radio signal e frequency counter.
  • Easy Battery level

Power On/Off                                    
Power On –Press and Hold down the [black key] by 2 second 
Power Off –Press and Hold down the [black key] by 4 second of number count down to 0
Charging the battery 
Plug the Power cord into adaptor , Micro USB connected SF-401, The Led indicating:
 *The RED Led is light - Charging        
 * The Green Led is light - Full 
How to check Frequency measuring.    See PIC.3

The transmitter near the frequency counter antenna , see the signal reception conditions is zone green, you can test. Please see Pic.3
cautions: 
e.g. display 1800.000Mhz  , The transmitter distance is too close to the frequency counter will affect the test results, , the signal bar is red .(see Pic.1)
e.g. display 0.000, , The transmitter distance is too far to the frequency counter and signal is weak ,will affect the test results,  the signal bar is low .(see Pic.1)
Note: (27MHz to 100MHz It can not be guaranteed and the corresponding normal emission appliance) .

How to check Frequency of Digital DMR Radio 
Press[ F3 Digital] from Measuring screen mode  
Note: Use Digital mode have 3 Decimal only

MENU funtion setting and save.    
Press [F3 down] or [F4 Up] into System and Press [F2 Rtn] into system Page PIC.4
Press[F3 down] or [F4 Up] select funtion ,Press [F2 Edit] > [F3 - ][F4 +] change mode
Press[Menu]  >  [F1 ]to Exit  or  [F4 ] to Save and Exit

(Do not directly connect a radio RF output by cable ,HIGH RF output will damage FREQUENCY counter )
