HFM Community Radio

 

Public Inspection Summary/Station Information

Provided as a courtesy to FCC inspectors and other interested parties.

 

Official on Air Date TBA

 

Section I Statement of Purpose and Disclaimer

a. The following is a compilation of all pertinent information that may be required by an agent of the FCC while inspecting or presenting a query to HFM Radio Studios. It may also be of interest to those who may be in the process of developing a Part 15 broadcast station. Please note that under any circumstances are the following parts of information to be taken as receiving legal advice from HFM Radio, it's agents, associates, or anyone associated directly or indirectly with HFM Radio.

     1. No liability is assumed for any information that is broadcast over the air using  the 1610 AM frequency. HFM Radio believes in the right to free speech under the Constitution. It is the listener’s responsibility to choose when to turn the dial if  the content does not agree with his or her views.

b. HFM Radio operates on the AM frequency under FCC Part 15 rules and regulations (Sec. 15.219 Operation in the band 510-1705 kHz.) and intends to fully comply with the same. While the right to free speech is important, HFM Radio is NOT a "Pirate Radio Station" and does not hide the location and/or the band on which it operates. Program schedules are publicly posted on the website and announced over the air waves. HFM Radio is self-funded and relies solely on donations and/or underwriters to fund it's activities. Underwriting fees will be collected  according to fluctuating rates assigned by HFM Radio.

c. 1610 AM HFM Radio is a private community oriented radio station. It's mission is to give the listening area an air wave voice of it's own. Local businesses, civic groups, churches etc. are encouraged to underwrite programs for broadcast.

Section II Content

a. The majority of broadcasts incorporate gospel music, old time radio re-broadcasts, music mixes created by HFM Radio software, and prerecorded church services but we will not limit or right to broadcast any content that we see fit. The DJs/guests/music aired on HFM Radio will not and do not make any statements that are racial, sexual, or anti-American in any way. People who seek to promote such services or products on the air will not be allowed to air on HFM Radio. We will reserve the right to deny any content that we feel is not appropriate for our format.

b. The primary programs aired on HFM Radio will be broadcast of prerecorded church services and music from local gospel music artists.  However, old time radio shows are played at various times throughout the week or weekend. Live broadcasts will be aired from time to time.

c. Public service announcements and commercials are also aired everyday.

d. We will  air national news at the top of the hour weekdays.

e. Local weather will be aired at random times during the regular programming.

f. Old Time Radio shows are occasionally played during the daytime and various night time shows, as well as music. No music is aired over unless it is copyright free, or verbal or written permission has been obtained from the artist. No old time radio show is broadcast unless it is researched and believed to be in the public domain. If you own or know of ownership of an old time radio show that is aired that is not public domain HFM radio will stop airing it at the time I am notified.

g. HFM Radio accepts no responsibility for content submitted for air. It will the  responsibility of the party making said submission to check all  items for any content  that is copyrighted or owned by other parties and seek permission for their use. Any fees due for use of content must be paid by the person/persons submitting the content and is not the responsibility of HFM Radio

Section III Ownership Profile

a. HFM Radio is owned by me and operated as a part of Harvest Field Ministries. There are no investors and no investments are solicited in any way. The owner and primary DJ (me) operates this station as a hobby for his enjoyment and the enjoyment of the local community.

Section IV Equipment and Signal Processing

a.  HFM Radio uses various amounts of hardware and software based equipment to create a professional broadcast on the air waves. The radio transmitter that is used is an unaltered AM1000 Rangemaster by Hamilton PCB Design (FCC Certified). The entire transmitter system is set up according to manufacturer instructions as it was certified by the FCC. No modifications have been made to the unit. No linears, or other power boosters are used.

1. The antenna is exactly 102 inches in length (as per FCC part 15 rules). The transmitter is mounted on top of a 25 foot  antenna mast. The total height is approximately 35 feet at the tip of the antenna whip to the ground.

b. Most all programs aired on HFM Radio are pre-recorded. This is done in order to create a better sounding production, and allow for hands free operation of the station, as this is a hobby and will not be manned at all times.  HFM Radio is a fully automated radio station . Live programs may be  aired from time to time, with most but not all live programs  recorded for later playback and archival purposes.

Section V Hours of Operation

a. HFM Radio  will normally broadcast 24 hours per day but this will not be guaranteed, as stated above this station is a hobby not a full time job.

b. HFM Radio on frequent occasions broadcasts replays of that day's radio program overnight. Therefore, the official operating hours of HFM Radio can be classified as both Day and Night with no definite stated scheduled hours of operation. Due to range restrictions at night, the day time broadcast offers the best reception for local listeners.

Section VI Station Frequency and Location

a. HFM Radio Studios are located on private property in Duplin County North Carolina. HFM Radio identifies with Rose Hill to give listeners the location of this station broadcast.

b. HFM Radio broadcasts on AM 1610. The current equipment configuration is considered in compliance with the part 15 rules, in good faith, to the best of my engineering capabilities.

Section VII Pre-Operation Testing and Surveying

a. Prior to operating the AM frequency portion of this radio broadcast, a number of internal/external surveys and tests were performed by me. This was to insure a clear signal, which would not impose on the rights of both licensed commercial stations and listeners of the same. Section b. describes this process in detail.

b. First, a general listing of North Carolina AM radio stations closest to the chosen operating frequency (1610) were compiled to the best of the my ability. Those stations which are as follows: (Please note that there may be others completely unknown to us) Please note that not all details of each station have been shown.

 Please note no station is listed at 1610 AM 

In addition to the location of known stations, it was also necessary to determine which frequencies could actually be received in the geographical area of the HFM Radio Studios. Therefore, the best test equipment available was a sensitive car radio which was taken out within a 3 mile perimeter of the HFM Radio Studios. If a frequency was clear at three miles out, then in good faith, it could be assumed that it would not interfere with the broadcasts of other stations. This test was performed during both day and night time broadcast hours. Also, spot checks were performed from the outer perimeter inward to the studio. 

In addition to radio station interference, television reception was also taken into consideration. Although most persons within the studio area are cable/satellite subscribers.

Before going on the air full time, a recorded test and announcement message will be played over the air at various intervals. The message will give  contact information and instructed anyone who was received any type of interference, to contact me immediately. No reports were filed as of this date. 

c. After conducting the basic initial research as listed above, no complaints have been noted, as well as no interference has been found by HFM Radio. 

Section VIII Periodic Testing

a. Periodic testing of the broadcast is conducted at regular intervals. This testing includes items such as listed in Section VII b. above.

b. Station Documentation/Logs

1. This station will keep a log of On-Air hours of operation for the AM broadcast for a period of six months or until the hard drive is full.

Section IX Rules and Regulations Pertaining to this Part 15 Radio Operation

( From the Rangemaster AM1000 website)

The AM1000 unit has been certified by the FCC and is legal to use as long as it is installed properly. However there are questions that come up on a regular basis. There is a statement on the FCC website that says that Part 15 transmitters only get 500 foot of range. We get asked regularly how transmitters such as the AM1000 can legally get 1-2 miles range in view of this statement. After talking with FCC officials about the statement basically the answer is that most AM and FM Part 15 transmitters are certified under Part 15.209 which is a radiation limitation. A Part 15 transmitter certified under this rule would get about 500 feet or so of range. AM transmitters certified under Part 15.209 are allowed 24000/F(Khz) micro volts per meter (at 30 meters) field strength. An example of this sort of transmitter would be a Childs toy or wireless microphone. However the AM1000 AM transmitter was certified under Part 15.219 which is not a radiation limitation but is a power and antenna length limitation. The power limit is .1 watt and the antenna length limit is 3 meters. There is no range or height limit for a Part 15.219 transmitter. With this allowed combination much greater ranges are possible, though it requires tune up and setting the power by a competent technician. Generally you can’t buy a Part 15.219 certified transmitter bubble packed at the department store. Because the AM1000 has a removable antenna and adjustable power, instruction to be installed by competent personal was a condition of certification. Rule 15.215 (a) clarifies this: “(a) The regulations in Sections 15.217-15.255 provide alternatives to the general radiated emission limits for intentional radiators operating in specified frequency bands. Unless otherwise stated, there are no restrictions as to the types of operation permitted under these sections.”

 Another legal issue is station identification. Here is the rule on that issue : (Title47 Sec. 73.3550)  Users of non licensed, low-power devices operating under part 15 of this chapter may use whatever identification  is currently desired, so long as propriety is observed and no confusion results with a station for which the FCC issues a license.

Another legal issue that comes up is the “What is the ground lead” issue. The part 15.219 (b) antenna 3 meter limit states “The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3 meters.” Examples of grounds could be a water pipe, massive metal structure that goes into the dirt ground, electrical ground, or other massive metal that connects to dirt. An important thing to remember with the AM1000 unit is that the unit needs to be properly grounded for the lightning protection circuitry to function properly. We recommend a large gauge massive copper wire from the transmitter box in a direct path as possible to a ground rod in the dirt or other suitable ground for lightning protection.
