What is the broadcasting power limit for a fm transmitter in the US?

I want to use the mobile black box V6000 (any one had any luck?)

Would you know where I can get the test report for it?

Check this site it should give you a good idea what the FCC considers legal.

Salient sentence from the link Mac posted:


On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters).

I wish Industry Canada could be as clear with their regs!

IC's regs (at least the ones I've found) talk about field strength at the edge of the property (1uV/meter, I believe).

It took a team of Googlers almost two years to find the right link on the FCC site ... I'm sure IC has one too, just merely hidden.

I send the CRTC an email last year about this exact subject and this is the reply i received. I'm not sure if this really helps or if this information i already available but i figured it might help someone out.

"Very generally speaking, you would require a licence if you were operating a station, the signal of which may be heard at a distance of over 30 meters. However, here's a link to our website that deals with certain types of operations which may qualify for an exemption from licensing. If certain criteria are met - no licence from the CRTC is required. http://www.crtc.gc.ca/eng/public/2003/8045/Exemption.htm


If you decide that your proposed operation qualifies for an exemption, you would NOT have to apply to us for a licence. But you would still have to contact Industry Canada to make sure your station's signal did not interfere with other operations. Locations and contact numbers for offices across the country can be found in the blue pages of the phone directory, or at their web site: http://www.ic.gc.ca/cmb/welcomeic.nsf/ICPages/RegionalOffices



If you have determined that you do not meet the criteria for an exempt service as described above, then you must look at licensing.



The following link will direct you to a general information page that gives an overview of the process for submitting new applications as well as provides other useful links: http://www.crtc.gc.ca/eng/INFO_SHT/b313.htm . Also, many applications (and all related documents) are already available in electronic format at our web site: http://www.crtc.gc.ca/eng/file/broadcast.htm"
