Honestly I am ignorant to what freqs. the async signals will utilize, but it must bring the noise floor up on HF at some point, to say otherwise would dispute everything I have experienced with RF. The providers and equipment companies will become sloppy in their work soon enough. Just like the pager industry and what it has done to vhf/uhf bands in metropolitan areas.]]> http://www.dslreports.com/forum/remark,9567385 Wed, 03 Mar 2004 11:30:05 EDT http://www.dslreports.com/forum/remark,9557364 anon : What about all the harmonics of the fundamental frequency? Notching out the ham bands does not necessarily notch out the harmonics.]]> http://www.dslreports.com/forum/remark,9557364 Tue, 02 Mar 2004 13:18:15 EDT http://www.dslreports.com/forum/remark,9557221 w2co : Well the ham bands are not the only places in the hf spectrum that are being used. You have the NTIA with hundreds of government/defense frequencies in heavy usage daily, you have FEMA with plenty of hf usage, the airlines transoceanic flight system on hf, what about the regular shortwave bands? Ham radio only takes up aprox. 6% of the 1-30Mhz spectrum. I am happy to hear that they are notching out the ham bands, but they will still have plenty of complaints after wide area deployment. The noise floor will steadily increase with each deployment, and with skipzone more and more into play, it will spell doom.]]> http://www.dslreports.com/forum/remark,9557221 Tue, 02 Mar 2004 13:05:07 EDT http://www.dslreports.com/forum/remark,9557097 yabos : So, if it doesn't emit any interference in the HAM and emergency bands then who cares.]]> http://www.dslreports.com/forum/remark,9557097 Tue, 02 Mar 2004 12:53:16 EDT http://www.dslreports.com/forum/remark,9556986 w2co : "He said the utility has found no problem with radio wave interference, a concern raised by many amateur radio operators."

Yeah well I suppose you would believe your used car salesman when he told you that your car did not put out exhaust gasses. Dream on - I won't get into the explanation on this subject anymore except to say that an rf signal introduced to an open wire WILL Radiate. Physics 101.]]> http://www.dslreports.com/forum/remark,9556986 Tue, 02 Mar 2004 12:42:39 EDT http://www.dslreports.com/forum/remark,9556882 Mactron : Alex Pardo of Cinergy said the Internet traffic travels on a separate band wave from the electric current, so there's no interference.
He said the utility has found no problem with radio wave interference, a concern raised by many amateur radio operators.

Lets hope it's true.;)
