Hi, Dave -
|
| According to FCC Part 15 regulations at
|
|
http://www.access.gpo.gov/nara/cfr/w...7cfr15_04.html ...
|
| you are not allowed to modify your equipment. Specifically...
|
| "Sec. 15.203 Antenna requirement.
|
| An intentional radiator shall be designed to ensure that no antenna
| other than that furnished by the responsible party shall be used with
| the device. The use of a permanently attached antenna or of an antenna
| that uses a unique coupling to the intentional radiator shall be
| considered sufficient to comply with the provisions of this section."
|
| Also...
|
| "Sec. 15.239 Operation in the band 88-108 MHz.
|
| (a) Emissions from the intentional radiator shall be confined within
| a band 200 kHz wide centered on the operating frequency. The 200 kHz
| band shall lie wholly within the frequency range of 88-108 MHz.
| (b) The field strength of any emissions within the permitted 200 kHz
| band shall not exceed 250 microvolts/meter at 3 meters."
|
| So, if you add an amplifier, you will exceed the maximum field strength
(by
| a bunch).
|
| Sorry to bring bad news.
|
| Good luck.
