My 60 year old transistor radio receiver has never
sounded better."

| “This transmitter worked
beyond the expected range, and the broadcast was very clear. It
was very simple to connect to our sound board.” |

“Everything worked great for our first
drive-in worship! We got a nice strong signal throughout the
parking lot. ” |
Pastor Paul Gebo
Christ Lutheran Church, Stockton, IL |

| “...have been impressed
since installing the Talking House Radio Transmitter in our
home.... I am just the typical guy who started working on old
tube type AM radios. What a wonderful way to give new clear
voices to old radios throughout the house.” |

couldn't have gone better. So thankful for your help.” |
Kerri Sandusky
First United Church of Christ, Tipton, IA |

| “We wish to thank you for
all your help in our purchasing of a radio system. For someone
who was not sure what was needed you took out all the guess
work.” |
Tom Barden
St. Andrews Episcopal Church, Wayne, ME |
| * * * |
| “So we did a test broadcast today of a
church service with only the pastor and one reader and a woman
with a guitar. And it was terrific - the speech quality was
excellent…and the sound quality of the music was very good as
well. All in all, it was a complete success... thanks very much
for helping to make this happen!” |
Phil Hirsch
Lamb of God Lutheran Church, Erie, PA |
| * * * |
| “I want to thank you for this helpful
product. We ordered the transmitter for our church services. I
was unaware that low-power AM transmitters were allowed under
FCC Part 15. It worked like a charm.” |
Gary Adams, Pastor
Kelham Baptist Church, Oklahoma City, OK |
| * * * |
| "Works really well. Used for outdoor
church service because of covid pandemic. Transmitter was
installed and hooked into sound board inside church with only
the included antenna hooked up, also inside church. The signal
was broadcasted all the way around the (decent sized) church.
Clear signal in every car. Was used with music and speaking.
Sound quality wasn't perfect but it was better than I expected
it to be considering it's an AM transmitter. Definitely worth
the money." |
Steven |

| “I like the see through glass on the
Range Extender. I can easily look up and check the peak from the
ground. I want to purchase another one very soon, as I am
pleased with this one. I will talk to some other churches and
ministries about installing a radio station.” |
| Bishop Ramon - DeMaria, TX |
| * * * |
| “Works really good. Much stronger
signal and will do what Church needs it to do and then some. I
may purchase another exact setup, for me, in the near future. I
really like the design and construction of the antenna/tuner!” |

Frequently Asked Questions
(Mouse over for
answers.) |
How can the InfOspot Transmitter operate without a
license?
The InfOspot TH.5
Transmitter is FCC-certified (ID #DLB5LTT98) and approved
for broadcasting under Part 15.219 of FCC rules, which allow
unlicensed operation of a certified 100mw AM transmitter
without a license as long as the antenna + ground does not
exceed 3 meters.
See: 15.219 - Operation in the band 510-1705 kHz. |
|
|
What are the FCC rules governing use of InfOspot?
Unlicensed Broadcasting
These are the regulations that apply to operators who want to broadcast without a license on the AM band. These regulations outline the technical details regarding field strength, power, and transmitter frequency accuracy, and permitted spurious emission limits. The original and full texts of these various sections are below, however, the most pertinent regulations for most Part 15 broadcasters include . . .
15.209 - Radiated emission limits
15.219 - Operation in the band 510-1705 kHz
15.221 - Operation in the band 525-1705 kHz.
Licensed
Part 90.242 of the rules of the Federal Communications Commission governs the licensing and operation of Travelers Information Stations (TIS). See also TIS FAQs.
|
|
|
Is there a way to broadcast with more signal coverage?
Yes, if you have an outdoor antenna. The same FCC rules contained in Part 15.219 govern use of both indoor and outdoor antennas. But an outdoor antenna and especially one mounted high above the ground will yield more range. The new Range Extender provides a way for you to do this. The Range Extender may be purchased with a new Talking House Transmitter system or added to an existing Talking House Transmitter System. Consider also the InfOspot system, which can include the i A.M. Radio option, the Range Extender option and other ancillary options, such as message players and weatherproof cabinets.
Yes, if you are an educational institution. Special provisions were enacted by the FCC in 1990 that allow unlicensed broadcasting of an AM signal that remains contained within the campus or grounds of the institution. No content, antenna, or output-power restrictions are enforced, and no license is required under FCC Rules Part 15.221. See also Extended Range.
Yes, if you are a governmental agency and/or if you provide emergency medical response. See FCC Rules Part 90.242 which govern this form of broadcasting under Travelers Information Stations. Up to 10 watts of power are allowed, and a license is required. See also Extended Range.

|
When I connect my InfOspot
Transmitter to the Range Extender Outdoor Antenna and Tuner,
is the coaxial cable between them considered part of the
ground lead?
It is not. The FCC certified the
InfOspot Transmitter for operation with the interconnecting
coaxial cable to its Outdoor Antenna and Tuner as a complete
system. Any length of coaxial cable may connect the
Transmitter with the Antenna and Tuner, because the cable
itself is not part of the antenna system. The InfOspot
Transmitter is also certified to operate on its own with a
3-meter wire (indoor) antenna. |
|
|
Why haven't you come out with a FM version of the
InfOspot System?
The FCC rules for unlicensed FM broadcasting under
FCC Part 15 limit the range of FM systems to just a few
feet. But under the corresponding AM rules, you can produce
a ¼ to ½ mile signal. That is partly because the FM rules
include a signal intensity limitation that keeps the signals
contained within100 feet.
To make matters worse, due to the
much shorter wavelength, FM signals are more easily blocked
and fade more quickly.
In addition, the FM band is much more
congested than the AM band, making an unused / quiet FM
channel very difficult to find.The legal range of AM non-licensed transmitter signals is not as severely restricted as FM, because AM Transmitters enjoy a 5000:1 power advantage over their FM counterparts. Even accounting for the lower antenna efficiency, legal AM transmitters have a typical range of up to 2500 feet depending on the antenna mounting height and location.
See "The Legal Range of FM Non-Licensed Transmitter Signals," a whitepaper by Paul Dobosz, 2020. |
