I had a nice conversation with the local COOP manager, but he was not interested in borrowing the people and equipment from another local utility to hunt down the problem(s). He left me with a caution that AM radio is dying, and that I should switch to broadband to hear what I want to from there. I didn't even get into being licensed and interested in getting back on HF, because that didn't seem to be on his radar, pardon the radio pun.

Consider the bigger picture...

You are a licensed, and protected service, you should START there. What you do currently, or are thinking about doing later, getting back into HF, has absolutely nothing to do with what may be their poorly maintained, or failing equipment creating RFI, and affecting communications. HF? Sure, you may hear it there, but when I'm sniffing around in a vehicle, I generally go to 1 GHz, and I check DC-12,000 MHz by hand. Noise doesn't stop at HF. RFI from power lines usually isn't a small problem, or limited to one person, or one band. I found one pole that affected a measured 18 square miles, in reality, probably closer to 50, but I gave up when I found the source. You hearing some noise on AM radio, or even HF can equate to everyone, everywhere, having everything affected. Really bad poles and lines wipe out local WiFi, and satellite downlinks in the GHz range. The average person generally doesn't know why their stuff acts flaky.

You are in the unique position of being the licensed guy, with all the rules and regs behind you. Chances are, nobody else even knows why everything hit the skids, and the average consumer with badly operating earbuds generally isn't listened to.

As for AM radio "dying out", perhaps for the one old uninformed/uneducated guy that doesn't bother to listen any more (some people don't listen to vinyl records either, but as of yesterday, a local Walmart had 3 sides of 2 aisles full of them, "vinyl is dead", someone said decades ago, go figure...), or believes internet rumours based on a few very poorly designed cars, however, in reality, in addition to almost every vehicle, or broadcast receiver ever made, a good portion of which still exist, and are used in the tens of millions daily, with hundreds of millions in reserve:

"National Association of Farm Broadcasting (NAFB) reports:

Efforts to keep AM radio in the dashboards of U.S. vehicles have taken a step forward in the House. The House Energy and Commerce Committee voted 45-2 to send the proposed AM Radio for Every Vehicle Act to the full House for a vote.

"It's been a stalwart of American prosperity and information sharing," says Representative Jeff Duncan (R-SC). "Having AM radio available is important to my constituents, especially during emergencies."

If passed by the full House, the proposed Act would require the Secretary of Transportation to issue a rule requiring access to AM broadcast stations in motor vehicles. If they don't, automakers would get fined.

The role of AM during natural disasters was cited by several lawmakers as they spoke during the bill's markup, noting that the Federal Emergency Management Agency spent millions solidifying the Emergency Alert System with AM radio as the backbone of the EAS.

In addition to serving as the backbone of the Emergency Alert System, AM radio remains a critical tool in delivering farm news and information to farmers across rural America.

Farm broadcaster and Vice President of Hoosier Ag Today and Michigan Ag Today Eric Pfeiffer says, "If AM radio gets removed from vehicles, it wouldn't be long before vehicle manufacturers remove FM radio or attempt to charge consumers for it. Hoosier Ag Today and Michigan Ag Today support free over the air radio for all consumers, especially farmers, and we encourage you to contact your members of Congress to ask for their support of the AM Radio for Every Vehicle Act."

As interesting as all that is, YOU are the one operating within a protected service, and RFI is no more permissible than any other crime against an individual, or society, in part, or whole. You are affected. That's all it takes.

Certainly one guy, in one co-op, can sniff one pole, one time. Besides, in addition to RFI to licensed or regulated services not being permitted by numerous CFR's, there's a lot more, requiring proper maintenance of power distribution systems. Find a really bad pole, preferably one that's visibly arcing, anonymously drop a dime to the utilities commission to shut down the system, and while being overhauled, use that as an opportunity (aka heavy leverage) to solve your RFI problem, cuz, you know, all those other poles making noise have the potential to catastrophically fail, or cause fires. Save humanity, save a radio, win-win.

You are in the position of power, and hold all the cards. If you "think" the RFI is power line related, based on your observations, it is up to the co-op manager to go to the time, effort, and expense, to find it, or not, and make a determination either way, kind of like saying to someone, I THINK that plane/train/automobile is going to go down/crash. Someone is gonna check... If you are unsatisfied with his response, find a another bottom feeding equivalent of a second level part-time McDonald's Shift Manager within the co-op to do his job for him, when asked the first time.
