NOUO for 1700 Khz AM No mention of 15:219

The NOUO mentioned 100 mW but mistakenly referenced 15.209 for this.  It also mentioned the field strength and correctly cited 15.209.

We can't tell from what is presented but perhaps the measured field strength was sufficiently strong at the distance of measurement that it would not be possible to achieve without violating 15.219 and presumptively 15.219 wouldn't apply..

I see nothing new here nor anything new to worry about.

Yes, it only mentions .209, it's curious, but not concerning.. I looked at it on google maps street view, it's a six story apt. building, I could not see a transmitter. I suspect the inspector didn't see one either, so the only code which he could cite would be .209

The transmitter might be inside an apartment, or perhaps on the roof. The notice was sent to the owner of the building. The owner of the transmitter can always respond that he's operating under .219 and an inspection can be made to confirm it.

I doubt it's an indication of a change of inspection methods or regulations, more likely it's just an indication of the particular circumstance.

There is an earler NOUO for FM at this location.  So probably on the FCC RADAR.

The FCC has been issuing NOUOs like this for a few years now, its likely the inspector saw the antenna system was not in compliance with .219 and automatically fell back to .209. (As is standard procedure)

Perhaps,... I havent really reveiwed many NOUO's lately, but in most cases in the past, if the inspector was able to see the installation then the details of that install was described in the  report and both .209 and .219 was mentioned.

I could see that if this was from an incident of an FM operator going WAY ABOVE the limit and causing some sort of interference that the FCC would want to keep this person shut down permanently and is making an example out of him. I have read NOUO’s where the whole process to how it was discovered was in the following pages.

I don’t have the link (maybe someone can help) but there was an NOUO for an operator of a Talking House AM Transmitter where as he was only using the wire antenna that came with it and was cited for going over 120 mW instead of 100 mW. Many thought it was an isolated incident but by evaluating these NOUO’s we can learn rather it is or is not.

There was the earlier myth that the FCC mainly concentrates on overpowered unlicensed FM operators but 14.1 uVm @ 98 feet (30 meters) is alarming because many folks report a 2 mile coverage with a properly installed elaborate unlicensed AM station. With a field strength that low I doubt you’ll cover close to a mile. So that would turn many AM stations to a little more than a Flycaster or Yardcaster same as FM. Is this what the FCC intends for AM as well?

I think your making to much out of this.

I compiled a list of every single NOUO for AM covering a three year span a few years ago, I've been meaning to update the list to make it current, but havent got around to it, but in that three year span there were a total of 7 NOUO's for AM, and several thoasand NOUO's for FM

I not sure which specific AM case your refering to, but if it happened between 2011 and the beginning of 2014 you'll find it here: http://part15lab.blogspot.com/2014/04/nouo-notices-of-unlicensed-operation.html  

By the way, I'm not sure your correct with your info about the Talking House NOUO.. 15.219 has no feild strength limit impossed on it. But I do recall a discussion a while back which had to do with a Talking House getting shut down, I don't recall the details.

May have been the Jerry Gaule incident.

It was reported his Talking House was operated inside his apparment with the wire antenna and shut down for non-compliance.  Some where on this forum there were discussions about it.

I my memory does not fail me I think the FCC Agent pulled his landlord into the act and that was the end of his Part 15 operation.

14.1uV/M @30 meters is such a small signal that even a car radio would hardly hear that. The transmitter probably wasn't even looked at. Canada's BETS-1 says 250uV/M@30 meters. How would the FCC check 100mW into final unmodulated if they don't have an electronics tech with test gear come and take measurements? A legal transmitter could have been operating in which case there's no limit on field strength. Didn't see the actual readings they got at 30 meters.

Apparently the Jerry Gaule incident involved a Rangemaster and long ground leads.. I'm still not sure which one is being talked about with a Talking House unit under .209.. http://www.part15.us/forum/part15-forums/regulations-law/rare-am-part-15-nouo-michigan-2014
