Exactly, Tim.

Mr. Wonderful was calling users of such devices pirates.  At best he was being disingenuous, at worst deliberately misleading.  It doesn’t appear that there’s anything wrong with using these Part 15(.236) certified devices, unlicensed, on the frequencies between 76-88 Mhz, as long as you don’t cause interference with other l…[Read more]

Whitespace devices have been around a while, and the issue has always been whether broadcasting was an acceptable use.  It appears, at least from this one agent’s comment, that it would be OK, as long as all the other provisions of the Whitespace rules are followed.

In my opinion, broadcasting is problematic in any event as the onus is up to the…[Read more]

Not all car mp3 players are under powered.  In fact, the FCC pulled a number off the shelves years ago for not being Part 15 compliant.  It sounds like the ones you’re using are OK.

Just to give you how much the Rolls is NOT compliant…

The amount of power required to meet the Part 15 FM rules is measured in nanowatts (around 20), not m…[Read more]

It’s actually not too bad for classical music, as most composers are long dead (well past the 50 years mandated in the copyright laws), and so you don’t have to worry about the music itself.  Canada changed the performance copyright laws in 2015 to extend them to 75 years after release, but anything in the public domain already wasn’t affected.  P…[Read more]

To make things even more complicated, each country has different copyright laws.  If you are located entirely in one country (corporately or individually), and stream from a server in that country, then only that country’s laws apply to you.  So you can’t, as an example, live in the U.S. and then stream from a server in Canada using Canada’s l…[Read more]

Copyright laws in the U.S. are a dogs breakfast.

This is definitely a biased article, but it does explain the issue.

I can appreciate the sentiment of wanting to do over-the-air radio.  I think that that’s the primary focus of most of us here (by the way, I really liked the audio clip on the RadioActive website).

The problem is that range is so limited for Part 15 stations that it limits the actual number of users that can listen in, particularly on cheaper…[Read more]

I’m close to getting my newly revamped Artisan Radio (with classical music) stream up and running.  I’m in the process of madly creating my automated playlist with public domain (in Canada) classical performances.

Once I get that done, I will be creating an opera program, again with public domain performances.  I intend to keep it ‘out of the o…[Read more]

I wonder what the field strength of the lightning was, and if it was in violation of Part 15?

Companies spend a lot of time and money on mission statements.  A good one is worth its weight in gold, and becomes the de facto marketing slogan.

The best mission statements are a sentence or two (maybe three).  That’s why they take such a long time to create.  It’s easy to meander along in your ‘About’.  It’s far more difficult to be acc…[Read more]

It’s the old chicken & egg problem.  What comes first?

The first digital TV broadcasters went out on a limb, well before there were millilons of TV’s with digital tuners.  Yes, there were digital TV converters, but they were misnamed – they just allowed you to receive digital TV and converted it to analog.  You didn’t get any (or at least not ma…[Read more]

I don’t have any problem with this either.

I did a bit of digging.  From what I can gather, the MA1 hybrid analog/digital system needs 30 Khz to operate in (compared to a 10 Khz mono analog signal currently).  The MA3 all digital system requires 20 Khz (it eliminates the 10 Khz analog mono).

Apparently the MA3 system is robust, eliminates n…[Read more]

The only way you’re going to get 4 miles range is with an LPFM.  Supposedly there might be an application window opening up in the next few years (I can’t remember where I saw that, but I did read it somewhere – it’s not all that important to me in Canada).

The basic problem with using wireless microphones for broadcasting is that it appears the FCC did not intend them for that purpose.

The FCC maintains a Whitespace Database, which contains events at which these microphones are going to be used, the geographic location, the date/times and the power levels.

ALL wireless microphone users are…[Read more]

I suspect that wireless microphone users in the U.S. in the 76-88 Mhz whitespace frequencies are meant to be similar to those in Canada.  These devices are not intended for Part 15 broadcasting as we know it (continuous transmission to general audiences in the 88-108 Mhz band), but rather targeted audiences in specific locations (such as…[Read more]

There still is talk about using wireless mic’s for Part 15 broadcasting in the whitespace frequencies 76-88 Mhz.

Has anyone ever found out if this is considered legal in the U.S.?  Are there any certified for that use?  I’ve heard of the Comtek BST-25, but most wireless microphones now use UHF frequencies, or high band VHF (170 Mhz & a…[Read more]

I’m inclined to side with RichPowers on this one.  2 miles is unrealistic, unless you’re dealing with a car radio (and even then it’s pretty unlikely), or are getting a signal induced into power lines (and you’re close to those power lines).

My experience with multiple transmitters is that I got about a mile, maybe a bit more, as the crow flies,…[Read more]

I remember that post clearly.  I also remember that some questioned its legality due to a long ground lead 🙂

I thought (and still think) it’s a great idea.  For a while, I toyed with the concept of a mobile FM station.  Strap down something like a Whole House or a Decade CM-10 to the back of the vehicle (beside the back window).  You could hav…[Read more]

The story keeps changing.

All I know is that your last statement certainly doesn’t hold in the real world for Part 15 MW broadcast signals.

But you’ve gone on record stating that you measured no field strength loss of a licensed radio signal due to an obstruction.
