TheLegacy,

Someone who I consider wise once told me “Freedom includes the ability to make an ass of yourself.”  Perhaps those who broadcast “objectionable” content, by whatever definition, are excising this freedom.

If some clown wants to broadcast such material so be it but I do not assume any guilt by association because I am a license free…[Read more]

What’s going on here?

A post questioning the appropriateness (is that a word?) of some alleged Part15 stations’ broadcasts has devolved into examples of what some may deem inappropriate.

If you think it is inappropriate then the solution is simple…don’t play it on your station.

I don’t know how this thread promotes or helps us at all.

Way off topic question and advice for RadioJoe.

Did you ever solve your hum problem with your KnightKit broadcaster?

I did so for mine.  The problem here was the signal was so strong that it was being modified by all the electronics throughout the house by means of these devices intercepting the RF and producing non-linear mixing with the 60…[Read more]

Thank you very much for report on your testing of various FM “car” transmitters.

Sorry, but I think it is not workable to promote range beyond a few hundred feet on the FM band since the regulations (15.239) technically and severely limit FM transmission range.

It is also necessary to consider the other requirements for 15.239 regarding purity…[Read more]

Thanks for the report and glad you had the chance to meet
Bill Baker.

I look forward to the day (not going to happen?) when the rest of us can run a 10 Watt transmitter and be “full quieting at three miles” with our signals .

Thanks to all who posted responsibly.

Thread locked.

Tim remarked “I’m perplexed by the comment about 25 minutes of advertising in an hour. I’ve never actually heard this anywhere, no matter how many complain about it.”

I am also perplexed but I measured this using a stop watch during the third hour of the Rush Limbaugh program aired on WTVN in Columbus, Ohio.  I stopped the watch if any comm…[Read more]

Mark, you make a good point that they can still play commercials because some are listening, however, the linked article demonstrates that the broadcasters apparently perceive a problem with declining numbers of  listeners.

I only spoke for myself in my previous post but I know my wife does not listen to broadcast radio, and neither do my sons…[Read more]

Thanks for the link which has content which I classify as wishful thinking.  Interference has never stopped me from listening to programming which I wanted to hear.  The reason I no longer listen to broadcast radio, neither AM nor FM, is that there is nothing I want to hear available and that I cannot stand 25 minutes per hour of commercials and s…[Read more]

Not knowing anything about this specific device I will make a general comment about spectrum analyzers applied to Part 15 devices.

For AM transmitters, an analyzer most likely will detect harmonics and spurs on the signal but, as Rich mentioned, the absolute amplitudes are not guaranteed to be accurate, but amplitudes relative to the carrier are…[Read more]

Got it.

At first I missed that your board has been modified and it does make sense to get pics of a good board to undo the damage.

Hope someone can provide this for you.

Part15Engineer wrote “I got schematics and a board layout from him (had to sign an NDA so i can’t give them out) but the schematic lacks part location references such a T1, R4, Etc.”

Help me understand your situation.  How would pictures of the board help you if you have the actual board in front of you?  It seems that having the pictures wou…[Read more]

I have found the opposite to be the case and  , in once case, have talked to Keith via telephone.  You should rely less on “friends” information and more on your own experience rather than conjecture.

He also wrote “…because Kei…[Read more]

Centinal,

I purchased an R PI a couple of years ago just to play with.  It does have audio and video capabilities but being a Windows experienced user with not much Linux experience I can only comment on what “canned” programs I found.

The platform supports Kobe which is an extensive player/server application which can import and play…[Read more]

Centenial,

You wrote “Other than my claim of original content, you want to see something more like the content found in this –”

To my reading of your original post, I could not connect the content to the general interest of a Part 15 enthusiast.  The two postings you cited are an offer for those interested to use their content in their pr…[Read more]

A reminder:  this forum is about supporting Part 15 radio.  I fail to see how the original post is relevant in this regard.

Also, anyone posting links should at least give a synopsis of the content so others do not waste time on things which do not interest them.  It would be helpful if those posting links add their own original reasoned co…[Read more]
