Band 40m

  1. 5w drive 18v psu = 140w
  2. 10w drive 18v psu = 250w
  3. 15w drive 18v psu = 320w
  4. 20w drive 18v psu = 430w
  5. 25w drive 18v psu = 540w
  6. 30w drive 18v psu = 620w
  7. 35w drive 18v psu = 730w
  8. 40w drive 18v psu = 820w
  9. 45w drive 18v psu = 940w
  10. 50w drive 18v psu = 1050w     

demikian hasil eksperiment saya. 73 sampai kita jumpa lagi
