Well, you see, you use both a top hat and a counterpoise.  That’s not just a wire up a PVC pipe.  It likely contributes to the good range you’re seeing (whether it’s legal or not is open to debate – there’ve been many discussions on this Forum).

The problem is that you’re reporting range that far exceeds others that have been reported by Part 1…[Read more]

Can you show us a video of your setup, including antenna?

This thread is supposed to be about the Range Extender, not changing the Part 15 rules.

If you must discuss desired rule changes (which have been discussed ad nauseum in the past), please start another thread.

If something is in the public domain, you can do anything you want with it.  So there would be no fees for broadcasting the material.

It’s really unfortunate that there is little case law to back up any OTR claims, re public domain or ownership.

There is the Silverman decision for Amos & Andy.  In 1948, CBS purchased the rights for Amos & Andy f…[Read more]

You’re correct in stating that copyright issues being the cause of the disappearance of otrrlibrary was speculation on my part.  However, it is informed speculation, as many, many, other OTR sites are disappearing.  otrrlibrary.org was one of the largest, and therefore, most visible.

There’s also no doubt that there is plenty of conflicting i…[Read more]

The fact as to whether a song creator is alive or dead is not the issue here.  Perhaps I haven’t been clear.

Old time radio shows were owned solely by the sponsors.  It was the sponsors who paid for everything (including music rights), eventually getting the master transcription disks, and it was the sponsors that decided their intrinsic worth a…[Read more]

Two things:

1.  Time does matter.  Why should people other than the creator(s) of the song benefit, i.e., why should the estate, which consists of people who had nothing to do with a song creation, benefit?  Those that were writing and performing songs and radio shows in the time period being talked about knew the terms and conditions of the th…[Read more]

Thanks for giving your thoughts, Mark.

I would disagree with your analysis of radio in the 50s & early 60s.  TV was taking radio’s audience, most entertainment was migrating to TV only (other than a few holdouts such as Jack Benny, who did both) and radio shows were being cancelled en masse.  Radio had to reinvent itself in the mid 60s as p…[Read more]

Apparently Randy Rainbow is on tour this summer/fall.  Only the U.S., which makes sense given his humor is largely politically-based, but still a shame.

He’s also received an Emmy nomination for Outstanding Short Form Variety Series.

All things considered, given your requirements, I would go with a Part 15 certified FM transmitter, such as the Decade MS-100.  It costs more, but is built like a tank, and is the highest quality.  You’re better off avoiding non-certified transmitters, as most that are advertised as ‘compliant’ really aren’t.  With all the current fuss over FM pi…[Read more]

The ProCaster is a high quality AM transmitter, and it is Part 15 certified.  To stay legal, the length of your antenna and ground lead must be less than 3 meters total .  That means either installing the transmitter at ground level with a short ground lead to your RF ground (rod driven into the earth/radials), or installing at height with no g…[Read more]

As it was stated previously in this thread, the Rolls transmitter is not legal for use in the U.S. (or Canada).  It is highly unlikely that 40mw output, even to a bad antenna, will produce a legal field strength.

BETS-1 certified transmitters in Canada are allowed much more field strength than the U.S. (100uv/m at 30 meters, as opposed to…[Read more]

Can you provide a link to the post?

I wouldn’t get too excited at this juncture about a meeting.  Being receptive doesn’t mean at all that the FCC will do anything about the state of Part 15 AM broadcasting.  In fact, if there were no next steps discussed, it means very little.  That’s why I’d like to get more information about the meeting, if I…[Read more]

Industry Canada really should, particularly for RSS123 and other licensed low power ventures (I don’t think they really know/care about BETS all that much).  It’s up to each potential IC licensee to hire an engineer (or something similar) to ensure that their desired signal doesn’t interfere with any existing stations.

It should be something…[Read more]

I don’t know how the Canadian one determines open frequencies, but the three it found for my location just didn’t work.

Applying the ‘listen’ test, 89.7 has a fairly strong station on it (89.9 has a very weak God station from Seattle that fades out in my area and I sometimes use it)

100.9 has a strong station on it, as does 102.9.  In addition…[Read more]

Actually, I do know the voltage of the power supply.  A plug run in parallel with the transmitter board supply also powers the CD-ROM.  A computer power supply will work (as long as it doesn’t introduce noise).

Sorry, but I just don’t have the knowledge, equipment and patience to fix the power supply.  I probably could if I wanted to and wa…[Read more]

I agree.

If, as the manufacturer claims, and the evidence indicates, the entire system is certified, then the amount of additional radiation introduced by the coax cable is insignificant.

In addition to that, the radiation introduced by coax in a properly matched antenna system is minimal, regardless of whether it is possible or not.

I suggest…[Read more]

I can answer a few of your questions.

The Rangemaster can (and should be) tuned to provide exactly 100mw input to the final.  There are two ways to do this.  They provide a module that indicates when you are exactly at 100mw, but I’ve never trusted that (the one I had was difficult to read).  However, there are also measurement points in the tr…[Read more]

I think we may be losing the forest for the trees.

What makes Part 15 broadcasting unique?  Playing the Top 40 hits along with all the other thousands of stations (no matter what genre you’re in)?  Reaching massive numbers of people like the much more powerful, licensed stations?

I think it’s being unique.  Unique programming.  A unique sou…[Read more]
