Just saw this NOUO which was from the same enforcement bureau that I was visited from and later talked about part 15:236 and the 50 mW output. Apparently the FCC is a say one thing and do the opposite agency because this NOUO clearly stated that the power limit for 87.9 Mhz was only 100 uVm at 3 meters and never mentioned 50 mW output nor certified whitespace devices. It seems as though there is a Hugh pressure to eliminate all receivable transitions from Hobby Broadcasters as well as a thorn in our side when we found this loophole in part 15 236. So its back to the drawing board and AM only for any real range for legal Hobby Broadcasting. transition.fcc.gov/eb/Orders/2019/DOC-357413A1.html |

So do you think it is because the use was not that of a wireless mic application? Rather, more of a broadcast application?
And so, they applied a different rule such as 209?

Interesting you brought this up Bob. I brought this subject up on Michelle Bradley's forum Part 15 AM&FM Hobby Broadcasting and according to the folks over there the issue was that more than likely the user didn't use a certified Wireless Mic, Headphone, or even Audio sender/receiver. And it was also discussed that I could advertise the frequency 84.828 (If I found a device like the ONN but at full 50 mW). But I could not say over the air "Your Rockin with The Legacy 84.828 and 1640 AM". I may get away with not giving the exact frequency over the air and say The Legacy 85 and my Website and 1640 AM. Then call the stream The Legacy 85 that way the FCC couldn't say I was branding the 84.828 frequency as a Radio station(Not intended for part 15:236).
This could get really tricky and end up full of litigation should this ever go to court. I suppose I could have found a audio sender/receiver device at full 50 mW that transmits between 76-88 Mhz Stereo. Then find a spot 1/2 mile to a mile further from me in a higher location that way I could justify my claim as an STL for my AM transmitter and advertise it on the Deltaville, VA page as "If you want to rebroadcast my station on part 15 AM and can receive my frequency on 84.828 Mhz let me know. This way I'm using it as an STL to multiple AM transmitters and also secretly using it as a way for hobbyist to hear me on an FM like quality signal on Radios that will go into the Japanese band.
I find this really concerning however knowing my intention this was not pointed out. Its almost like the FCC partly opens a door but also gives you little enough info so you screw up and they have a reason to bust you once again and that would be a second felony offense that would get me banned from ever being on the air period. I'm not about to screw up.
I think we really need to look into this further I smell something rotten here.

Howdy All: Here is my opion!.
1) There is too much missing information to make a judgment call !.
2) The Fcc need to be more informative on there nouo in whats happening
at the Scene like writing a police report to make a call on whats going on!.
3) Jumping to conclusion's don't make you look good unless you have
Other evidence for back up!.
Just putting my 2 cent in
Have a great day
Operator

Well, I don't know the specifics of this case either, but I suspect this individual wasn't trying to play the wireless mic angle, anyway, and didn't make those arguments. My guess is the subject transmitter wasn't approved for use as a wireless mic and the operator was simply broadcasting as opposed to sending the signal to a recorder or amplifier as .236 specifies. Probably wasn't command and control traffic, either. Not that it matters what s/he was doing, it's a matter of strictly following the rules so we don't get into trouble. I think strict adherence to the regs and being able to explain it if challenged is what counts.
I believe broadcasting on this frequency should be allowable with an approved transmitter if its ancillary to transmission to something like a PA amplifier, recorder or for command and control usage. It might also be good to use it as an STL, but since .236 is specific about transmitting to an amplifier, recorder or for C&C, I don't think using a wireless mic for an STL link alone would necessarily be sufficient.
I had thought about using a good quality wireless mic as an STL in conjunction with my Part 15 transmitter on the AM broadcast band. It could also transmit to a recorder in a more accessible part of the building to record everything broadcast on the main AM Part 15 frequency. By putting it on 87.7 or 87.9, I could check the link using pretty much any FM radio. I think recording off a professional quality wireless mic is going to give me a cleaner signal than recording the AM transmission off an AM radio.
Well, it sounds legal to me. Feel free to poke holes in this conclusion if you wish. I think its at least worthy of consideration.

I posted about an AM antenna Loop under antennas and I think this is going to be the way to get my range. There are several different brands in which I'm going to try to find the best of to tell my listeners about. This way they will receive my station really nice.

I'd say your listeners really love you if they'll go to the trouble of doing this and that's a wonderful thing. In my case, I think it would be easier just to link another transmitter to improve coverage. Fortunately, I own a building on the other side of town that should be in just about the right spot for a second transmitter. I'm going to tell the tenants it's a device to monitor if they're tearing the place up... John W9LWA |

Great idea if you own property why not use it. Plus the people in the apartment can hear your station and you can put signs up. What a great thing.

Indeed, I'm still leaning toward that, but things are on hold for the moment as I want to see what kind of range the new TH external antenna tuners get. I'd always planned to get Rangemasters as it's my understanding they are the only ones we can really network. But, if the range of the TH is enough greater with the elevated antenna capability, I might just go with that and not mess with networking. I guess we should be learning more about the TH soon enough... John W9LWA |
