Incorrect.
Jim "Ari Silversteinn" wrote in message ... BTW, it is 24000/F uV/m at 30 meters from 490 to 1705 kHz., which is more like 100 feet, not 1000 feet (15.209). Jim So if I need to go out 3500 feet or so, this won't work. Correct? -- Drop the alphabet for email |

You are correct Jim, mistyped the extra zero.
"RST Engineering" wrote in message ... Not quite. That is the limit in 15.209, with the following caveat "...except as provided elsewhere in this subpart..." Elsewhere in the subpart (15.219 and 15.221) we have the limit for the band 525-1705 kHz. (AM broadcast band) the 100 mW and 3 meter antenna restriction OR a 15 uV/m restriction at a distance of (47.715/(frequency in kHz.)) meters (which is also lambda/(2 * pi)) from leaky coax. BTW, it is 24000/F uV/m at 30 meters from 490 to 1705 kHz., which is more like 100 feet, not 1000 feet (15.209). Jim "Fred W4JLE" wrote in message ... Richard the value changes per band and is stated in part 15. For example in the broadcast band the formula is 24000 /F for microvolts at 1000 feet. |

Which zero?
