Why is not the ham's fault???
Because most of them operate within FCC limits.
CB radio types......OTOH........are notorious for flaunting the law. They should be fined when caught. Problem is, they are almost never caught.
Most audio gear has little, if any, design consideration to minimising the effects of EMI. I am a manufacturer, as well as a "ham" and an audiophile. There is a good chance I speak with authority on this subject.
AC line cords......interconnects....speaker leads.......all make for good antennas. Any one, or a combination of them could be the source of your misery.
As an engineer, I would first want to know the transmitting frequencies, and the field power. But as that is not something you are likely to be able to supply us, let's try a different approach.
The next time you experience an extended period of interference, turn off your system, and disconnect the amp from the preamp. Place a shorting plug in the input of the amp, and turn it back on. Let us know what, if anything, comes out the speaker that does not belong. That is the first step to determine waht piece of gear we need to operate on.
