FCC 74-87

The FCC is such a great pack rat when it comes to saving paperwork. Some of you may already have seen this, but while trolling around the FCC website today I came across a document simply titled 74-87.It is a reply from the FCC to a Mr. Victor Fischer, dated February 13, 1974. Mr. Fischer petitioned the commission for a waiver to relax the part 15 rules regarding the technical limitations imposed for transmitting on the AM band. While I can't re-print the entire letter, I did find some interesting statements from the FCC in reply to the waiver that bears quoting."3. Part 15 of our rules permits operation in the AM Broadcast Band of a miniature transmitter, called a Low Power Communication Device, without an individual license provided that the input power to the device does not exceed 100 milliwatts and that the total length of the transmission line plus the antenna does not exceed 10 feet."Notice that no mention is made of radials or a ground."4. In essence, the petitioner proposes that the Commission suspend the technical limitations in Part 15 to permit him to carry on a non-licensed operation providing a coverage and service that would resemble a regular broadcast operation. Because relaxation of the technical specifications and operating conditions set out in Part 15 would greatly increase interference potential to the regular broadcast service, the Commission has not granted such requests as the petitioner's in the past. The intent of Part 15 is to provide the radio enthusiast with an opportunity to experiment with radio, entertain friends or neighbors within a very limited communication range. The Commission never intended that Part 15 be used to establish a low power broadcast facility to service an entire community."As you can guess Mr. Fischer's petition was denied and the letter is signed Vincent J. Mullins, Secretary.As we've suspected, the FCC only tolerates the use Part 15 devices for community broadcasting without giving a full endorsement to the service. I know that some are now petitioning the FCC to increase the Part 15 power level to 1 watt so it will be interesting to see if the FCC will soften its stand on the Part 15 rules or not.Given the interference issues surrounding HD radio on AM and the FCC's push to allow IBOC for nighttime use, I somehow doubt it. db
