Why Does this always happen to me.

Now, How do I rid myself of this problem?

Most interference from Ham Radio is easy to fix and usually only requires some simple filtering or grounding.Occasionally, antenna proximity or transmitter power is the problem. Then you will have to make a decision or so as how to handle this.You won’t be interfering with your neighbor’s vacuum cleaner,,,,, but………..

Let me count the ways

R.F. from other stations Power Line Noise Computer or peripherals Televisions Telephone systems AM or FM Radios Furnaces or Controls Antenna Amplifiers Garage Door Systems Touch Lamps Lighting Systems Wireless Controls Auto Engines VCR or Sat Receiver Anything with an Oscillator or CPU in it

Listen to the sounds and do not confuse them with the many digital modes of operation such as PSK, MFSK, THROB, Digital SSTV, RTTY, TOR or any of the others that you may not heard before or are not familiar.
