LORAN 100 kHz 2150 UTC 4 Aug 2016

[ChrisSmolinski]

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.

[ChrisSmolinski]

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

H.R.1678 - National Positioning, Navigation, and Timing Resilience and Security Act of 2015/
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.
