New LF band, 136KHZ

While not strictly TC related, the following does
have some bearing because of the frequencies involved.
There are also a few hams on this list:-)
The following is from the ARRL (American Radio Relay
League, www.arrl-dot-org) posting of a new ham radio band
in the low freq spectrum of 136 KHz. Previously the
lowest band was 1800-2000 KHz.

136 kHz Band Would Mark First LF Allocation for Hams
The ARRL asked the FCC for two LF allocations in
October 1998--135.7 to 137.8 kHz and 160 to 190 kHz.
The petition had languished at the FCC until this
month, apparently in part because of concerns
expressed over the 160 to 190 kHz request. Unlicensed
experimenters--some of them hams--currently operate on
LF in the US under the FCC's Part 15 rules.
"This action proposes changes that would enhance the
ability of amateur radio operators to conduct
technical experiments, including propagation and
experiments, in the 'low frequency' (LF) range of the
radio spectrum," the FCC said in its Public Notice.
The 135.7 to 137.8 kHz band that the FCC appears
willing to grant adheres to the European Conference of
and Telecommunications Administrations (CEPT) band
plan. Several countries in Europe and elsewhere
have 136-kHz amateur allocations. The first amateur
transatlantic contact on the band was recorded in
2001. The ARRL has proposed allowing General and
higher-class amateurs to operate a transmitter at up
W PEP output, but in no case greater than 2 W EIRP
(effective isotropic radiated power).
Hams would be secondary to the Fixed and Maritime
Mobile services in the 136-kHz allocation. The League
its engineering surveys suggest that hams could
operate without causing problems to power line carrier
systems already active in that vicinity or to
government assignments. Unallocated Part 15 PLC
systems are used by
electric utilities to send control signals, data and
