    RichPowers replied to the topic Car Transmitter Testing continues! in the forum Transmitter Talk 3 years, 1 month ago

    It’s because your transmitter is from another country:

    “..FM radio stations all transmit in a band between 88 megahertz (millions of cycles per second) and 108 megahertz. This band of frequencies is completely arbitrary and is based mostly on history and whim. Inside that band, each station occupies a 200-kilohertz slice, and all of the slices…[Read more]

    It’s because your transmitter was intended to be used in a different country:

    Why do all [US] FM radio stations end in an odd number?

    Last week HB member Tom Tompkins posted a review about a very inexpensive ($3.95) lSS-02 Audio Ground Loop Isolator’ available on eBay, which apparently performs remarkably well. After he received it he ran it through a battery of test utilizing a signal generator and a vacuum tube voltmeter and detailed all results, along with picture of the…[Read more]

    I’m sure your right Mark, I haven’t looked at the manual Tim provided, but did note that even the ISS Products page specifies the TR6000 can be used for “unlicensed broadcast operations under FCC Part 15.221”

    Tim mentioned: “But notice it says Part 15.221 and specifically states for carrier current or educational campus uses.”

    There’s an interesting side story about that.. which may derail the thread a tad, but it’s still in the ball park of the subject on hand;

    Recently I’ve been researching the use of part 15 in Drive-ins, and in the book ‘Drive-in…[Read more]

    “adjustable wattage for zero to 30 watts” – Just set it to zero.01 I guess.

    RichPowers replied to the topic Where Are They Now? in the forum Transmitter Talk 3 years, 3 months ago

    adjustable wattage for zero to 30 watts. I run it legally with a legit length antenna and ground . It covers about a few miles and thats all i want

    Very cool find Tim, but you realize you have to have it set at a maximum of 100mw to operate it under part 15 – which means, if the adjustments are properly set, it’s highly unlikely to be capable of…[Read more]

      The ISSTR 6000 is adjustable from 0 to 10 watts carrier. The 30 watt led scale is for PEP. If you need any info message me . I’ve been tuning these units for years probably retuned 300 of these units already.

    I consider the following appropriate to post here under Regulations/Law. If the moderators deem it more appropriate under a different category then I have no objection if it gets relocated…

    For anyone concerned about legally operating a Part 15 community station, one should be thoroughly familiar with the famed KENC station, what he did right,…[Read more]

    Somebody… I thought it had been in this forum, but perhaps elsewhere, but somebody (I kind of thought it had been Mram, but apparently not) had described in detail how they utilized a common alert radio along with some common utilities to create an automatic EAS type on air alert system that automatically kicked in and interrupted the current…[Read more]

    The ALPBS current address is http://thealpb.from-ak.com/ but I think that’s tempore.

    The ALPB forums changed to http://mbcf.boards.net/ some time back (the name changed to “Micro Broadcasters Community Forum”

    Don’t know what video your talking about, but I seriously suspect the NAB could care less one way or the other if part 15 broadcaster  broadcast emergency info or not, or much of anything else…

    But you have an interesting idea, however you could probably get by a lot cheaper and less cumbersome than using an car stereo to do it. There’s…[Read more]

    Sounds interesting. You say they’re sold on eBay, but when I searched eBay for ‘Cuthbert Compressor’ to find how much they cost it turned up no results. Do you have a direct link?

    RichPowers replied to the topic NEW MUSIC FEES COMING? in the forum Regulations / Law 3 years, 4 months ago

    Ok, I think I kind of get it now.. OTA stations in the US do have to pay BMI, who in turn pays only the original writer of the song, but stations don’t pay other royalties to anyone else.. Not the artist, neither singer or band, not the composition or production,  not anyone other the writer. – Is this correct?

    If so, then that would better…[Read more]

    RichPowers replied to the topic NEW MUSIC FEES COMING? in the forum Regulations / Law 3 years, 4 months ago

    I’m still confused.. In the U.S, if OTA stations have never been required to pay royalties for the music they play (except for their online streams), then where did the idea come from that OTA part 15 stations need to pay royalties?.. I always interpreted it as because it’s considered a “public performance’ like jukeboxes or even live bands at…[Read more]

    RichPowers replied to the topic How to stream ZaraRadio? in the forum Broadcast Equipment 3 years, 4 months ago

    For example, when I follow the instructions to go to streaming – Playlist, Add Internet Stream – I get a little box that asks for the duration of the connection and insert the URL.

    That’s so when you insert a source from the internet to add to your playlist it will know how long to stay connected before resorting to your local playlist, oth…[Read more]

    RichPowers replied to the topic Another step toward digital AM in the forum General Discussion 3 years, 4 months ago

    I’m surprised it says it can increase usable signal range.. Everything I’ve read indicates digital AM inheritently results in a decrease of  range.

    Have I misinterpreted something?

    Oh! I didn’t realize how old this thread was! For a much simpler method of streaming with Zara you might want to scroll up towards the top of this page to my December 25, 2010 post, using Broadwave and virtual audio cable made things quick and easy to set up.. I was up and going in minutes. I forgot all about that, it was so quick and easy to…[Read more]
