Speed Deterent with 'Fake' Radar Signal?

Without getting closer than I want, I can't tell if a thing on the dash is a radar detector or a dash cam.

You are worried about legal trouble over broadcasting a radar signal.....

Then advise him to use his tractor, tear up the road, and make speed bumps on a state highway??:confused2:
Yes, that was my immediate thought also and same reaction. :confused2:

Looks like a part 90 license may be needed?

PUBLIC NOTICE
FEDERAL COMMUNICATIONS COMMISSION
Released: December 9, 1996 DA 96-2040

The FCC continues to receive many inquiries about regulations governing police radar, radar detectors, and other radar devices used to measure the speed of an object. This Notice explains the scope of FCC regulation over these devices. It updates and supersedes the Public Notice on the same subject dated August 1, 1985.

Radar units are transceivers, i.e. they both transmit and receive a signal, and operate under rules for the Radiolocation Service contained in Part 90 of the FCC's Rules. As such, they are certified and authorized by the FCC under Parts 2 and 90 of the FCC's Rules. Part 90 specifies the frequencies and technical standards for radar units, but does not address how radar units are to be operated as devices to measure an object's speed. Also, the FCC Rules do not contain provisions concerning the calibration of radar units, the reliability of the readings, or operator capability requirements.

Radar units are used by police and other public safety agencies to measure vehicle speeds. Under Part 90 of the rules, licensees in the Public Safety Radio Pool (such as state or local government entities), that already have a FCC license for a radio communications system, may operate radar units without obtaining a separate license for them. Radar units may also be used under Part 90 by non-public safety entities such as professional baseball teams, tennis clubs, automobile and boat racing organizations, private transportation firms, railroads, etc., to measure the speed of objects or vehicles. Non-public safety users, however, are required to obtain a Part 90 license from the Commission for use of radar units. Additionally, many public safety agencies also operate unattended, low-power, transmit-only radar units under Part 15 of the FCC's Rules.

The National Highway Traffic Safety Administration (NHTSA) is the federal agency concerned with the enforcement of highway speed limits and with the operation of radar as enforcement tools. Information on NHTSA regulations concerning radar use can be obtained from the Department of Transportation, National Highway Traffic Safety Administration, 400 Seventh St., S.W., Washington, D.C. 20590.

Radar jammers are transmitters tuned to interfere with ("jam") a radar signal. The intentional use of jammers is considered "malicious interference" and is strictly prohibited by the Communications Act of 1934, as amended, as well as by FCC Rules. Anyone using a jammer risks such penalties as losing an FCC licenses, paying a fine, or facing criminal prosecution.

Radar detectors are radio receivers tuned to receive radar signals and are used by motorists to provide a warning of any radar activity in the vicinity. In this regard, the FCC regulations pertaining to receivers do not address the subject of radar detectors. The use of radar detectors by members of the public, therefore, does not constitute in itself a violation of FCC Rules. Some jurisdictions, however, have local regulations or statutes concerning the use of radar detectors. Inquiries about such statutes should be directed to local law enforcement authorities.

In summary, the FCC Rules regulate radar transmitting units but provide limited regulation over receivers, with the subject of radar detectors not being specifically addressed in the FCC Rules. For more information about the subject of this notice, contact the Wireless Telecommunications Bureau, Public Safety and Private Wireless Division, at (202) 418-0680.

FEDERAL COMMUNICATIONS COMMISSION RADAR GUNS Title 47 Code of Federal Regulations - Telecommunications Part 90 - Private Land Mobile Radio Services Subpart H - Policies Governing the Assignment of Frequencies Rule 90.20 Public Safety Pool Rule Section 90.20(f)(4) states:

"A licensee of a radio station in this service may operate radio units for the purpose of determining distance, direction, speed, or position by means of a radiolocation device on any frequency available for radiolocation purposes without additional authorization from the Commission, provided type accepted equipment or equipment authorized pursuant to 90.203(b)(4) and (b)(5) of this part is used, and all other rule provisions are satisfied. A licensee in this service may also operate, subject to all of the foregoing conditions and on a secondary basis, radio units at fixed locations and in emergency vehicles that transmit on the frequency 24.10 GHz, both unmodulated continuous wave radio signals and modulated FM digital signals for the purpose of alerting motorists to hazardous driving conditions or the presence of an emergency vehicle. Unattended and continuous operation of such transmitters will be permitted." No Federal Communications Commission requirement exists that the make and model of the radar gun be recorded on the radio station license.

Yes, because microwave bands used for police radar are governed, regulated and licensed by federal agency(s) FCC for one). Besides, laser speed measurements are the most common ones around here in Michigan because the aim point is more accurate to target a suspected speeding vehicle.

Now, here in Michigan, many roads designated at 30 mph are gravel roads, so I may have presumed your road is gravel/dirt. My mistake. Gravel roads are county and state regulated. So, less jurisdictional weight. 'speed bumps' or washboarding on gravel roads is a naturally occurring process caused by braking of cars and trucks, so who's to say who 'caused' a speed bump to appear. Works very well on my road. The neighbor's hub cap collection was growing for a while but has now settled down (speed and alloy wheels).

But its your science project. You seem to presume that your speedsters are all equipped with radar detectors. I'd bet they are not. Otherwise get a sheriff out their for a few days a month to ticket the guilty. Don't be surprised if your neighbors fall into the trap, though.

"For police radar you need to have an FCC license to operate. For LEO's this is covered by their license to use public safety radio bands. I'm not sure how a non LEO could get around that as they are not allowed to use public safety bands and the radar bands (K, X, Ka, etc) are all partitioned for LEO use.

Laser on the other hand has no licensing issues."

I believe the licensing may be dependent on power level, frequency, and emission type and may be covered under part 15 for low power devices such as 'radar' sensing on a door opener in a store or similar which will set off a radar detector. Also newer cars have a collision detection which evidently use K band transmit/receive frequencies. My own detector will alarm continuously if I get behind a car equipped with this from several hundred feet back.
Is your radar detector just a new-car detector? - Autoblog

Start shopping for a retired police car to place in a strategic location. Even for folks used to it, they still tend to slow down.

Put up a sign every couple of weeks.

+1 on avoiding issues with Part 90. As anyone with a ham license knows the FCC doesn't mess around with fines on that stuff(easily gets into the 5 figures).

Best way to keep people flying down the street is probably make it physically impossible. I'd work with you local town/county to see what you can do to get speed bumps installed. If it's a residential road it should be pretty straightforward.
