I am confused about something. I fully understand the legality of part 15 AM operations when it comes to transmission. The only thing that needs to be clearified is the range of AM transmission. Here is what I read on the FCC website concerning part 15.219 and it states:
PART 15 DEVICES
Unlicensed operation on the AM and FM radio broadcast bands is permitted for some extremely low powered devices covered under Part 15 of the FCC's rules. On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters). See 47 CFR (Code of Federal Regulations) Section 15.239, and the July 24, 1991 Public Notice. On the AM broadcast band, these devices are limited to an effective service range of approximately 200 feet (61 meters). See 47 CFR Sections 15.207, 15.209, 15.219, and 15.221. These devices must accept any interference caused by any other operation, which may further limit the effective service range. For more information on Part 15 devices, please see OET Bulletin No. 63 ("Understanding the FCC Regulations for Low-Power, Non-Licensed Transmitters"). Questions not answered by this Bulletin can be directed to the FCC's Office of Engineering and Technology, Customer Service Branch, at the Columbia, Maryland office, phone (301) - 362 - 3000, e-mail LabHelp@fcc.gov.
Now if you pay close attention where it says range of 200 feet in AM transmission. Doesn't that contradict the range for several miles of operation under part 15.219 where it states 200 feet? I know the power limits are low to 100 miliwatts and the FCC will not come after you if you abey the rules, but what about this ruling I just posted?
Anyone want to comment on this?
