Re: WARNING NOTICE 
EB-FIELDNER-16-00023244
To whom it may concern:  
It has come to the attention of the Federal Communications Commission that 
Gatekeeper Amps is marketing unauthorized radio frequency devices in violation of 
Section 302(b) of the Act
1
 and Section 2.815(b) of the Commission’s Rules.
2
  
Federal law requires that radio frequency devices must be certified in accordance 
with the Commission’s technical standards before they can be marketed in the United   
States.  Section 302(b) of the Act provides that “[n]o person shall manufacture, import, 
sell, offer for sale, or ship devices or home electronic equipment and systems, or use 
devices, which fail to comply with regulations promulgated pursuant to this section.”
3
  
Section 2.815(b) of the Commission’s Rules provides that external radio frequency power 
amplifiers capable of operation on frequencies below 144 MHz may not be offered for 
sale unless they have first been authorized in accordance with the Commission’s 
certification procedures.
4
  Section 2.815(b)(1) of the Rules prohibits persons from 
offering for sale any external radio frequency power amplifier
5
 that is capable of 
amplification in the frequency bands between 26-28 MHz.
6
  
In particular, the Commission received a complaint that Gatekeeper Amps, an on-
line retailer of Citizen Band (CB) radios, linear amplifiers, and radio accessories, was 
building and repairing high-powered linear devices for sell.  Based upon the information 
provided in the complaint, it appears that Gatekeeper Amps violated Section 302(b) of 
the Act and Section 2.815(b) of the Rules by marketing and offering for sale 
1
 47 U.S.C. § 302(b).

 47 C.F.R. § 2.815(b).
3
 47 U.S.C. § 302(b).
4
 47 C.F.R. § 2.815(b).
5
 An external radio frequency power amplifier is defined as “any device which, (1) when used in 
conjunction with a radio transmitter as a signal source is capable of amplification of that signal, and (2) is 
not an integral part of a radio transmitter as manufactured.”  See 47 C.F.R. § 2.815(a).
