Hearing the familiar sound of LORAN on 100 kHz. Running MultiMode shows that it is the Great Lakes chain, with stations Dana and Seneca.

I have looked for Loran signals on 100KHz from the Asia/Pacific region and heard nothing, there used to be a Loran station in Gippsland, in Australia but it closed down some years back. Also there was one in Yap, Eastern Caroline Islands in the Pacific but I think it too has been shut down some time ago.
Only thing I have noted down the bottom of the band is the JJY Time Signal on 60KHz from Hagane, Japan at 50Kw some 7,743kms from here, logged during my summer. So good to hear there are some Loran stations still about.
Also I see mention of BPL on 100KHz from Shaanxi, China too but never heard it, maybe off air also? What is the transmitter power of those two you logged? Jack VK2XQ.

I am not sure of the exact power level, my understanding is they were in the several hundred kW range.
They are still on the air now, 1350z on 8 Aug 2016.

Dana was (is?) 400 kW & Seneca was (is?) 800 kW

TITLE I--POSITION, NAVIGATION, AND TIMING
SEC. 101. SHORT TITLE.
This title may be cited as the ``National Positioning, Navigation,
and Timing Resilience and Security Act of 2016''.
SEC. 102. BACKUP GLOBAL POSITIONING SYSTEM.
(a) In General.--Subtitle VIII of title 46, United States Code, is
amended by adding at the end the following:
``CHAPTER 807--POSITION, NAVIGATION, AND TIMING
``Sec.

``Sec. 80701. Land-based complementary and backup system
``(a) In General.--Subject to the availability of appropriations,
the Commandant of the Coast Guard, in consultation with the Secretary
of Transportation, shall provide for the establishment, sustainment,
and operation of a reliable land-based positioning, navigation, and
timing system to provide a complement to and backup for the Global
Positioning System (in this section referred to as `GPS') to ensure the
availability of uncorrupted and nondegraded positioning, navigation,
and timing signals for military and civilian users in the event that
GPS signals are corrupted, degraded, unreliable, or otherwise
unavailable.
``(b) Requirements.--The system established under subsection (a)
shall--
``(1) be wireless;
``(2) be terrestrial;
``(3) provide wide-area coverage;
``(4) deliver a precise, high-power 100 kilohertz signal;
``(5) be synchronized with coordinated universal time;
``(6) be resilient and extremely difficult to disrupt or
degrade;
``(7) be able to penetrate underground and inside
buildings;
``(8) be capable of ready deployment to remote locations;
``(9) take full advantage of the infrastructure of the
existing, unused Government long-range navigation system
(commonly known as `LORAN');
``(10) incorporate the expertise of the private sector with
respect to development, building, and operation;
``(11) work in concert with and complement any other
similar positioning, navigation, and timing systems, including
enhanced long-range navigation systems;
``(12) be available for use by Federal and non-Federal
government agencies for public purposes at no cost; and
``(13) incorporate such other requirements determined
necessary by the Commandant.
``(c) Implementation Date.--Not later than 180 days after the date

such date of enactment.''.
(b) Clerical Amendment.--The analysis for subtitle VIII of title
46, United States Code, is amended by adding after the item relating to
chapter 805 the following:

H.R.1678 - National Positioning, Navigation, and Timing Resilience and Security Act of 2015/ (https://www.congress.gov/bill/114th-congress/house-bill/1678/)
Sponsor: Rep. Garamendi, John [D-CA-3] (Introduced 03/26/2015)
Committees: House - Armed Services
Latest Action: 08/13/2015 Referred to the Subcommittee on Strategic Forces.
IN THE HOUSE OF REPRESENTATIVES
June 20, 2016
Mr. Hunter (for himself and Mr. Garamendi) introduced the following
bill; which was referred to the Committee on Transportation and
Infrastructure
A BILL
To require the Secretary of Defense to establish a backup for the
global positioning system, and for other purposes.
Be it enacted by the Senate and House of Representatives of the
United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the ``National Positioning, Navigation,
and Timing Resilience and Security Act of 2015''.
SEC. 2. FINDINGS.
Congress finds the following:
(1) Global Positioning System (GPS) satellite signals are
used by all critical infrastructure sectors in the United
States and are crucial to the reliable and secure operation of
defense systems operated by the United States Armed Forces.
(2) Use and dependence on GPS signals in the United States
continues to grow.
(3) GPS signals are relatively weak and consequently unable
to reach many indoor environments or underground installations,
which limits their use for first responders, law enforcement,
the Armed Forces, and other users.
(4) Due to the relative weakness of GPS signals, such
signals can be easily corrupted, degraded, or denied access to.
(5) There is an increasing use of inexpensive and widely
available GPS jammers by organized crime syndicates and rogue
states.
(6) A prolonged disruption of GPS signals caused by jamming
or other cyber security threats would cause serious national
security, intelligence, and economic disruption for the United
States.
(7) Since 2004, the Federal Government has recognized that
the absence of a reliable backup system for GPS is a glaring
economic and security threat to the United States, and has
reaffirmed its interest in developing an enhanced long-range
navigation system (LORAN), or eLORAN, as a reliable land-based
backup for GPS signals.
(8) The establishment of a land-based positioning,
navigation, and timing backup system to complement GPS as soon
as practicable is essential to secure the economic and national
security interests of the United States.
SEC. 3. BACKUP GLOBAL POSITIONING SYSTEM.
(a) Establishment.--Section 2281 of title 10, United States Code,
is amended by--
(1) redesignating subsection (d) as subsection (e); and
(2) by inserting after subsection (c) the following new
subsection:
``(d) Land-Based Complementary and Backup System.--
``(1) In general.--The Secretary of Defense, in
consultation with the Commandant of the Coast Guard and the
Secretary of Transportation, shall provide for the
establishment, sustainment, and operation of a reliable land-
based positioning, navigation, and timing system to provide a
complement to and backup for GPS to ensure the availability of
uncorrupted or non-degraded positioning, navigation, and timing
signals for military and civilian users if GPS signals are
corrupted, degraded, unreliable, or otherwise unavailable.
``(2) Requirements.--The system established under paragraph
(1) shall--
``(A) be wireless, terrestrial, and wide-area;
``(B) provide a precise, high-power 100 kilohertz
signal;
``(C) be resilient and extremely difficult to
disrupt or degrade;
``(D) be able to penetrate underground and inside
buildings;
``(E) take full advantage of existing, unused
government long-range navigation system (commonly known
as `LORAN') infrastructure;
``(F) incorporate the expertise and contributions
of the private sector to quickly establish a system
architecture, build, and operate a land-based GPS back-
up system; and
``(G) work in concert with and complement any other
similar positioning, navigation, and timing systems,
including enhanced long-range navigation systems
(commonly known as `eLORAN').''.
(b) Implementation Date.--The Secretary of Defense, in consultation
with the Commandant of the Coast Guard and the Secretary of
Transportation, shall ensure that the system required under subsection
(d) of section 2281 of title 10, United States Code, as inserted by
subsection (a) of this section, is fully operational not later than
three years after the date of the enactment of this Act.

The antenna at Jupiter, Fl. is all gone. Not sure when but it has been gone for some time now.
I questioned the decommissioning as I am sure lots of others did. Not smart. I just don't trust GPS even though I use it. Too many vulnerabilities. I think I still have a LORAN receiver. Need to go check the stash.
