FM25B • 30
SUMMARY
The present edition of Part 15 of the FCC rules does not provide detailed
guidance on ALL aspects of using a low-power transmitter such as the
FM25B. The main point is that you may not cause any interference whatso-
ever to licensed broadcast services and that you must be willing to put up with
any interference that you may experience.
In addition to operations not requiring authorization, you also have the option
of writing a clear and polite letter to the FCC Engineer-in-Charge of your local
district, describing your intended operation. Mention the operating frequency
and planned hours of operation. This could be a good step to take if your pro-
ject is in behalf of a school, Scout or community group.
If you become further fascinated with the service rendered by low-power
broadcasting, other FCC regulations explain how to apply for a license or
other authorization which may permit you to upgrade your FM25B or other
equipment to accomplish any objective which the FCC sees to be in the public
interest and not interfering with other authorized uses of the radio spectrum.
Lawful use suggestions
1. Build and adjust this kit strictly according to the published instructions.
2. Use the whip antenna supplied with the Ramsey case set, CFM.
3. Do not modify your kit in any way.
4. Check your intended operating frequency very carefully, as clearly ex-
plained in this instruction manual, to ensure you will not cause interfer-
ence to reception of licensed broadcasting.
5. If you receive ANY complaint about your transmissions interfering with
broadcast reception, stop or change your operation IMMEDIATELY.
6. If you are contacted by the FCC regarding use of this device, cooperate
fully and promptly.
7. Do your own homework and research to understand and comply with pre-
sent and future FCC rulings concerning devices of this kind.
8. Do not use made-up "station call signs" to identify your transmissions.
Only the FCC has the authority to issue such call signs. Use some other
way to identify your transmitting activity, such as "This is Stereo 90.5,
Seabreeze School Student Music Radio," and so forth.
9. Identify the location and purpose of your transmissions from time to time.
This is common courtesy toward other persons who may hear your signal.
The FCC is toughest about clandestine transmission which cost time and
money to track down.
