There is another reason to consider. RFI is another form of growing pollution 
and what company would want to be front and center in another battle over 
pollution.

There are a lot of reasons, Tony, and which ones mean what to which 
manufacturer is speculation.

Here are some possibilities, in no particular order:

o They want their company to have a good reputation, and with amateur 
complaints, this would not be the case.
o The ghost of BPL Past still haunts then, and they do have relationships with 
utilities to fill them in on what happens when there is controversy.
o They want to be good corporate citizens.
o They do not want the FCC to start adjudiucating cases. I told them the Texas 
story and they don't want to be on the wrong side of bad FCC decisions.
o They do not want stricter emissions limits, so they want to be able to say 
that the existing rules are wortoldking.
o They do want to reduce emissions enough that there are few, if any, 
interference complaints.
o They know that ARRL can be a great friend to those companies that go above 
and beyond.  We did that with Good Guys in the BPL wars and their "above and 
beyond" made it into the international standards for BPL.
o They know that ARRL can be a formidable enemy.  The publicity of what the Bad 
Guys in the BPL wars prevented that industry from getting a foothold.  
Utilities stayed away in droves because the word was out that if the systems 
were operated legally, they didn't work well, and it they were operated "hot," 
"Ed" would show up and there'd be bad publicity for the utility and involvement 
with the FCC.

It's is amazing, though, to see how many companies respond appropriately.  When 
Phonex made "wireless modem jacks" that operated on 3.53 MHz, there was 
interference. When contacted, they redesigned the product to not use the ham 
bands.  They had been  told that amateur radio was a "dying breed." They 
learned quickly to the contrary.  AT&T has bought them by the 10s of thousands 
and rather than trying to squash us like a bug, they did a system-wide  recall 
of installed devices, actually sending trucks out with spectrum analyzers and a 
whip antenna to find the devices when they didn't have good records by contract 
installers.  It was industry that contacted ARRL, wanting to testing of the 
developing HomePlug standard that was in-premise BPL before it was even called 
that.  They ended up choosing to notch the ham bands, creating an industry spec 
that did not cause harmful interference to amateur radio.  When RFI was getting 
into Eaton AFCI breakers, when we reported this to them, they s
   ent two engineers from CA to witness our findings and had a redesigned model 
available within 6 weeks, replacing them in the field in response to 
complaints, even paying the electricians.

Yes, there are uncooperative companies, but most are made up of engineers that 
want to do the right thing.  I keep myself less cynical so I can help ensure 
that when those engineers do the right thing, it pays off for them in good 
publicity and avoidance of trouble.
