Dear Sir or Madam:

This is an official **CITATION**, issued pursuant to Section 503(b)(5)
of the Communications Act of 1934, as amended ("Act"), 47 U.S.C. §
503(b)(5), for marketing in the United States a police radar jamming
device manufactured by Rocky Mountain Radar ("RMR"), specifically, the
RMR-C450 device, in violation of Section 302(b) of the Act, 47 U.S.C. §
302a(b), and Sections 2.803, 15.205 and 15.209 of the Commission's Rules
("Rules"), 47 C.F.R. §§ 2.803, 15.205 and 15.209. As explained below,
future violations of the Commission's rules in this regard may subject
your company to monetary forfeitures.

On February 22, 2007, the Spectrum Enforcement Division ("Division") of
the Enforcement Bureau received a complaint alleging that Chumbo.com is
marketing the RMR-S201 and the RMR-C450 devices. On April 2, 2007, the
Division staff visited Chumbo.com's internet web site at
[www.Chumbo.com](http://www.Chumbo.com/) and observed that Chumbo.com is
marketing the RMR-C450 device. The Division staff observed that
Chumbo.com was not marketing the RMR-S201 device at that time. The
Division staff also observed that Chumbo Corporation is doing business
as Chumbo.com.

On January 31, 2007, the Division issued a Notice of Apparent Liability
for Forfeiture ("*NAL*") proposing a \$25,000 forfeiture against RMR for
marketing the RMR-C450 device[^1] in apparent willful and repeated
violation of Section 302(b) of the Act and Sections 2.803, 15.205 and
15.209 of the Rules.[^2] In the *NAL*, we noted that the Commission's
Office of Engineering and Technology ("OET") Laboratory had obtained a
sample of the RMR-C450 device directly from RMR for testing.[^3] Testing
of the sample indicated that the unit is designed to emit a signal that
intentionally interferes with a licensed radio service (police radar),
and is indeed capable of interfering with police radar.[^4] Therefore,
the OET Laboratory concluded that the device is an intentional radiator,
as described in Section 15.3(o) of the Rules, 47 C.F.R. § 15.3(o).[^5]
In addition, the OET Laboratory's tests indicated that the RMR-C450
device produced a radiated emission at 11.23 GHz, a restricted frequency
band listed in Section 15.205 of the Rules, 47 C.F.R. § 15.205, and that
this radiated emission substantially exceeds the radiated emission
limits for intentional radiators specified in Section 15.209 of the
Rules, 47 C.F.R. § 15.209.[^6] The OET Laboratory also concluded that
the RMR-C450 device was improperly certified.[^7] In this regard, the
OET Laboratory noted that the grant of certification issued for the
RMR-C450 device indicates that the device was tested as an
"unintentional radiator."[^8] As explained above, however, the OET
Laboratory found that the device is an intentional radiator.

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." Section
2.803(a)(1) of the Rules, 47 C.F.R. § 2.803(a)(1), provides that:

> no person shall sell or lease, or offer for sale or lease (including
> advertising for sale or lease), or import, ship, or distribute for the
> purpose of selling or leasing or offering for sale or lease, any radio
> frequency device unless ... \[i\]n the case of a device subject to
> certification, such device has been authorized by the Commission in
> accordance with the rules in this chapter and is properly identified
> and labeled as required by § 2.925 and other relevant sections in this
> chapter.

Pursuant to Section 15.201 of the Rules, 47 C.F.R. § 15.201, intentional
radiators must ordinarily be authorized in accordance with the
certification procedure prior to marketing. Section 2.803(g) of the
Rules, 47 C.F.R. § 2.803(g), however, provides in pertinent part that:

\[R\]adio frequency devices that could not be authorized or legally
operated under the current rules ... shall not be operated, advertised,
displayed, offered for sale or lease, sold or leased, or otherwise
marketed absent a license issued under part 5 of this chapter or a
special temporary authorization issued by the Commission.

Further, Section 333 of the Act, 47 U.S.C. § 333, prohibits any person
from willfully or maliciously interfering with or causing interference
to any radio communications of any station licensed or authorized by the
Commission. Moreover, Section 15.205 of the Rules, 47 C.F.R. § 15.205,
prohibits radiated emissions, other than spurious emissions,[^9] in any
of the restricted frequency bands listed in that section. Thus,
intentional radiators that cannot legally be operated -- because, for
example, they interfere with or jam licensed police radio facilities or
operate in restricted frequency bands -- are not eligible for a grant of
equipment certification. Finally, Section 15.209 of the Rules sets forth
the radiated emission limits applicable to intentional radiators.

As noted above, contrary to the claims of RMR, the RMR-C450 device is an
intentional radiator. The device is not, however, eligible for a grant
of certification because the device's intended purpose is to interfere
with Commission authorized radio facilities, specifically, licensed
police radar, in violation of Section 333 of the Act, and the OET
Laboratory has determined that the device in fact is capable of
interfering with police radar.[^10] Moreover, there are two additional
grounds for finding the marketing of the RMR-C450 device to be unlawful.
The RMR-C450 device is not eligible for a grant of certification because
it produces a radiated emission in the restricted frequency band at
11.23 GHz in violation of Section 15.205 of the Rules.[^11] This
radiated emission also substantially exceeds the radiated emission
limits for intentional radiators specified in Section 15.209 of the
Rules.[^12]

The record before us indicates that Chumbo.com apparently is and has
been marketing the RMR-C450 device. Accordingly, it appears that
Chumbo.com has violated Section 302(b) of the Act and Section 2.803 of
the Rules by marketing the RMR-C450 device, which is not eligible for a
grant of equipment certification because the device is intended to
interfere with licensed police radar, in violation of Section 333 of the
Act. Chumbo.com has also apparently violated Section 302(b) of the Act
and Sections 2.803, 15.205 and 15.209 of the Rules by marketing the
RMR-C450 device, which is not eligible for a grant of equipment
certification because it produces a radiated emission in the restricted
frequency band at 11.23 GHz, and which produces emissions that
substantially exceed the radiated emission limits for intentional
radiators.

**[If, after receipt of this citation, Chumbo.com violates the
Communications Act or the Commission's rules in any manner described
herein, the Commission may impose monetary forfeitures not to exceed
\$11,000 for each such violation or each day of a continuing
violation.]{.underline}**[^13]

Chumbo.com is taking to ensure that it does not violate the Commission's
rules governing the marketing of intentional radiating jamming devices
in the future.

**The nearest Commission field office is the** **St. Paul District**
