Manufacturer Information

  • Make/Model: MFJ 269B
  • Part Number:


not specified


  • Read the manual before using
  • Do not remove from shop (parking lot okay)
  • Do not leave without charging if vbatt drops below 13V. Vbatt is displayed on the LCD at boot, and a charging cable is included in the box.
  • Do not power on with UHF button depressed. Press UHF button AFTER power up. If you are surprised by this, you didn't read the manual. Please do that.


Currently unit is acting crazy and probably needs a transistor replaced. It seems to work somewhat better after running a while.
