Must be. As "we" all know from reading 14 pages here, it's never, ever the ham's fault
Nah, it comes for free with a Zed subscription.
I was going to renew. Now you have me wondering.
Occasionally, it is the fault of the amateur radio operator. However, the vast majority of the time it is the fault of the affected equipment. Most people don't even read, let alone understand, the 47 CFR Part 15 notice, on the equipment, that says the equipment cannot cause interference to other devices and that it MUST accept interference from other devices.
When someone purchases, especially for a substantial amount of money, an item that person expects the unit to be free from interference. Unfortunately, consumer product manufacturers, as a cost cutting measure, do not provide adequate shielding, r.f. bypassing, etc., that would reduce, often eliminate, any interference from r.f. devices. The manufacturer is relying on the fact that only a very small percentage of the devices are going to be in a situation where additional shielding, etc., is required and, by not including such, the profit margin is increased.
In the past, most interference, that was actually the fault of the amateur radio operator, was due to harmonics generated in the transmitting equipment. However, with the reduction in over-the-air television reception and the fact that most television is now received via cable or via satellite, harmonics are no longer a serious problem. Unfortunately, r.f. overload, caused by elimination of shielding, etc., in consumer devices, is now the source of the vast amount of situations where an amateur radio transmitter is concerned.
How an individual amateur radio operator reacts to interference complaints is important. Technically, in the vast number of cases, the operator is well within his / her legal rights not to do anything to try to correct the problem. But, working with most complainants can usually defuse the situation and allow corrective measures to be undertaken. Of course, there are those individuals, on both sides, who refuse to cooperate and then things can get very "sticky".
Not "never, ever".
But usually it isn't the ham's "fault" at all.
People complain about things that happen when the amateur is not on the air. They assign blame for things that defy all logic. They have no concept of how radio or technology work, yet they are SURE of what's going on.
@WB2WIK had the classic experience: Put up a tower and beam, ran the coax into a bucket. No ham gear in the house at all. Neighbor saw the antenna and complained of TVI and all sorts of other bad stuff.
It puzzles me that some people want to live in a technological society, with all its benefits, but don't want to see the technology itself. As if it is somehow "obscene" and "ugly". They want perfect cell phone coverage everywhere but no cell sites. They want cheap, plentiful, dependable electricity and natural gas, with no power lines, no pipelines, no substations, no solar panels, no wind turbines, no power plants, no gas drilling, no refineries.
Such people should NOT be calling the shots.
Assigning blame on others is a great American pastime. No logic required.
Now if they would only listen to what the voices they are hearing inside the walls from the antenna is actually telling them...
Not "people" but rather some people complain...
Conversely, it's unimaginable that in now 15 pages, there is no example of the ham being/taking responsibility for a problem. That was the point of my comment, not a blanket statement as you imply. Please don't twist what i clearly said sarcastically to suit your purpose
Yeah, but how do you know what they hear from these voices is benign?
They can always call Ghost Busters.
Does the operation of a transmitter result in problems? Of course! However, with the exception of harmonics, from the transmitter, causing the problem, the amateur radio operator is NOT "responsible" for the problem. The responsibility rests with the manufacturer of the affected unit the vast majority of times. There are, occasionally, situations where the owner / installer of the affected unit is at fault and their actions are the primary reason for the interference.
As I pointed out before, how the individual amateur radio operator "handles" the situation plays a very important part in getting the situation straightened out. The very first thing that needed to be done is to verify that the amateur radio transmitter is involved. Sometimes the transmitter is involved and sometimes the transmitter actually plays no role in the situation.
When the transmitter is not involved, then it is in the amateur radio operator's advantage if he / she can assist in finding and then, hopefully, eliminating the source of the problem.
If the transmitter is involved, then offering advice, sometimes even supplying things like Ferrite to reduce, even eliminate, the interference, often defuses the situation. I definitely recommend NOT making modifications or even attaching items to the affected items. This is because doing so will then put the operator, at least in the mind of the owner, in a situation where any subsequent problem with the affected item, will be blamed on the operator. Such may happen years down the road and, according to the item's owner, the amateur radio operator is at fault. Providing advice or even the items required to eliminate the interference, but letting the unit's owner install the items, or pay someone else to install the items, is definitely the way to go!
Yes, there are situations where the affected units owner is completely unwilling to work with the operator. This situation is even worse when the operator's transmitter is not causing any interference. Then, there is the situation where the interference is imagined and then made public by some individual. Those are the hardest cases to solve if they can be solved at all.
