Lets assume that the IF of the missile receiver
is 1.2 MHz
48.5 MHz
Mix 48.5 MHz 49.7 MHz in the receiver, and get
1.2 MHz Which equals the IF Which results
in Cross-modulation in the receiver!
49.7 MHz

Conclusion

• A total of 319 guided bombs used in 65 operations
• 215 functioned correctly, achieving a hit rate of
  49.3
• 40 Allied warships and 39 merchant vessels sunk
  or put out of action for the loss of 48 aircraft
• Compared to regular bombing, this was a
  phenomenal success rate!
• Had these weapons been available earlier in the
  war one shudders at what could have happened
