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.

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.

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]

If I were an engineer (which I am) and was analyzing the “Range Extender” (which I am not) I would be very interested in measuring the efficiency of the device.  What is the loss in the coils and tuning slugs?  How much power is lost in driving the metering circuit?  Bottom line is how much power is delivered to the antenna system with a given DC…[Read more]

TheLegacy wrote “You’ll fry it at more than 100 mW because of its low rated parts inside. ”

You may well be right but how do you know this?  Is there a published specification from the manufacturer which states the maximum power handling capability?  Any documentation regarding maximum power?

Otherwise, it is best if speculation not be used.

John,

This has potential to be a very useful discussion.  I suggest we look at features and functions separately, e.g. a feature is the transmitter is indoors rack mounted, and function is to produce maximum radiated power.  I hope we don’t get wrapped around the axle and distracted by ground leads for now and just explore what can be p…[Read more]

Folks, read the linked article if you wish but I do not see how, with the direction this thread is heading that it will end well.

Locked.

Neil

And you know this how?

Please try to keep to the original topic when replying, especially to questions pertaining to a specific topic.  Though TheLegacy’s post is interesting and deserves a read it did not address the question posed and could have been better presented in a new thread.

Thanks,

Neil

Regarding the National Memorial Day Parade, do whatever you feel is appropriate.

My plan is to go dark and my stations will be off the air on Memorial Day in homage to those of us who are now silent.  There is nothing I can do or say to honor those of us who are now gone other than to silently bow in remembrance of them.

Artisan wrote “If they’re beside each other, there’s probably nothing to worry about.”

This is certainly true since receivers in a near field of a transmitter, and those in high strength fields can produce many artifacts, so what is a license free broadcaster to do to separate artifacts from reality?

Say I am using a transmitter for license fre…[Read more]

Thanks for sharing your experience and demo via video.

What may happen with this idea for an improved receiver/antenna scheme could be similar to a subscription service where people will be willing to pay to gain access to programming they value with a slight difference being that the hardware expense is reasonable and is a one time only…[Read more]

When lead paint is found on children’s toys or emission cheating by a car manufacturer is found it seems the government action is swift and sure, so why not in cases such as this.  Enforcement needs to include the manufacturers and distributors in a greater extend, and to a lesser extent to end users.

Few end users have the knowledge or…[Read more]

Troy,

The video was well done and I only meant to offer a suggestion.  There is a lot of potential in what you can share via video so please keep going with this.

Neil

Artisan,

Thanks for the reply.  I asked question 1 with the thought that it was perhaps “perfectly acceptable” to the Part 15 broadcasters based on my reading of years of posts here and elsewhere, perhaps due to either lack of enforcement or knowledge of the .219 restrictions and your response suggests it was a change in FCC interpretation, or…[Read more]
