§15.219 Operation in the band 510-1705 kHz. (a) The total input power to the final radio frequency stage (exclusive of filament or heater power) shall not exceed 100 milliwatts.
(b) The total length of the transmission line, antenna and ground lead (if used) shall not exceed 3 meters.[glow=red,2,300][/glow]
(c) All emissions below 510 kHz or above 1705 kHz shall be attenuated at least 20 dB below the level of the unmodulated carrier. Determination of compliance with the 20 dB attenuation specification may be based on measurements at the intentional radiator's antenna output terminal unless the intentional radiator uses a permanently attached antenna, in which case compliance shall be deomonstrated by measuring the radiated emissions.

A little more info and the reason I am wondering if the FCC is cleaning up some rather grey area's in the rules.
Subpart B—UNINTENTIONAL RADIATORS
§15.101 Equipment authorization of unintentional radiators. §15.102 CPU boards and power supplies used in personal computers. §15.103 Exempted devices. §15.105 Information to the user. §15.107 Conducted limits. §15.109 Radiated emission limits. §15.111 Antenna power conduction limits for receivers. §15.113 Power line carrier systems. §15.115 TV interface devices, including cable system terminal devices. §15.117 TV broadcast receivers. §15.118 Cable ready consumer electronics equipment. §15.119 [Reserved] §15.120 Program blocking technology requirements for television receivers. §15.121 Scanning receivers and frequency converters used with scanning receivers. §15.122 [Reserved] §15.123 Labeling of digital cable ready products.

The wording for the antenna system has been as noted in your post as long as I can remember.
Are you thinking the "transmission line" is new? I have a copy of the rules from 10/1/09 and it is the same as your post.
