  • ARRL Still Seeking Vintage DXpedition Logs for Archive

    ARRL continues to solicit paper logs of prominent DXpeditions that took place predominantly in the 1950s, 1960s, and 1970s, for inclusion in The DX Log Archive Endowed by JA1BK. The DX Log Archive program was created, thanks to an endowment established by Kan Mizoguchi, JA1BK, to obtain, preserve and utilize paper logs from rare and significant DXpeditions. The archive can include pre-1950 pape...

  • Amateur Radio Poised to Retain Full 76-81 GHz Band, Sharing with Vehicular Radars

    In a draft Report and Order (ET Docket No. 15-26) to be considered at its July 13 open meeting, the FCC is proposing to lift a nearly 2-decade-old suspension of Amateur Radio access to 76-77 GHz, giving the Amateur and Amateur-Satellite services access to the full 76-81 GHz band on a secondary basis. The FCC also reduced Amateur Radio’s status from primary to secondary in the 77-77.5 GHz segmen...

  • Hunting For Daytime NDBs In CLE 220
    AP-378 Mayne Island, BC


    It's hard to believe but this coming weekend will see another CLE challenge!





    No need however, to stay up until the wee hours for this one, as CLE220 is a mid-day affair ... just log what you are able to hear during the day from your location. The entire band is fair-game as well, from 190 - 1740kHz.

    Everyone is encouraged to send their logs (see below) so the RNA / REU NDB databases can be kept as up-to-date as possible.

    I know that I won't have any trouble hearing AP-378 shown above since it's only about 3/4 mile from my antenna! I'm always curious just how far it can be heard during the day and would encourage listeners on the west coast to have a good listen for it and please let me know if you can hear it.

    For those unfamiliar with this monthly activity, a 'CLE' is a 'Co-ordinated Listening Event', as NDB DXers around the world focus their listening time  usually on one small slice of the NDB spectrum.

    When tuning for NDBs, put your receiver in the CW mode and listen for the NDB's CW identifier, repeated every few seconds. With your receiver in the CW mode, listen for U.S. NDB identifiers approximately 1 kHz higher or lower than the published transmitted frequency since these beacons are tone-modulated with a 1020 Hz tone approximately.
    For example, 'AA' near Fargo, ND, transmits on 365 kHz and its upper sideband CW identifier is tuned at 366.025 kHz while its lower sideband CW ident can be tuned at 363.946 kHz. Its USB tone is actually 1025 Hz while its LSB tone is 1054 Hz.

    Often, one sideband will be much stronger than the other so if you don't hear the first one, try listening on the other sideband.

    Canadian NDBs normally have an USB tone only, usually very close to 400 Hz. They also have a long dash (keydown) following the CW identifier.

    All NDBs heard in North America will be listed in the RNA database (updated daily) while those heard in Europe may be found in the REU database. Beacons heard outside of these regions will be found in the RWW database.

    From CLE organizer Brian Keyte, G3SIA, comes the usual 'heads-up':

    Hi all

    SUMMER MIDDAY EVENT

    How many normal NDBs can you log around midday?

    In this event we can probably cheat the QRN and hardly hear any (but if
    you do have a midday storm coming overhead, disconnect and switch off
    immediately of course)

    Listening around midday is a good way to check our listening stations and
    to find out if changes really have made improvements in reception.
    Or maybe you could try the CLE listening from a 'field' location instead of
    (please, NOT as well as) from home?

    Days: Fri. 23 June - Mon. 26 June
    Times: Within 2 hours of ‘real’ Midday (see below)
    QRG: 190 - 1740 kHz
    NDBs Normal NDBs only, plus any UNIDs
    (not DGPS, NAVTEX or Amateur)

    ### IMPORTANT ## If your house clocks have moved one hour
    forward for 'summer time' (or 'daylight saving'), your listening
    times each day will be BETWEEN 11 IN THE MORNING
    and 3 IN THE AFTERNOON (15:00) on your LOCAL clocks.

    If your clocks were NOT changed, maybe in Arizona (?), or
    in the Southern Hemisphere where it is now mid-winter,
    your times each day will be from 10 a.m. to 2 p.m. LOCAL.

    (The above matches our agreed definition for daytime listening)
    Of course, all our logs will show UTC times, as always.

    Our usual simple log-making 'rules' apply:
    Post your CLE log to the List in a plain text email if possible please,
    with CLE220 at the start of its title, showing on each log line:

    # The Day No.(e.g. ‘23’) or the full date (e.g. ‘2017-06-23’)
    and UTC (the day changes at 00:00 UTC).
    # kHz - the nominal published frequency, if known.
    # The Call Ident.

    Please show those main log items FIRST, with any other details such as
    location and distance LATER in the same line.

    Don't forget to give your own location and brief details of your equipment.
    It also makes good reading if you add your thoughts on the CLE and any
    amusing events that happened during it.

    I will send the usual 'Any More Logs?' email at about 17:00 UTC on Tuesday
    so you can check that your log has been found OK. Do make sure that your
    log has arrived on the list by 08:00 UTC on Wednesday 28th June at the
    very latest.
    I’m so grateful to Joachim who will again be making the combined results for
    us.

    As usual, you can get further helpful information about this and past CLEs
    via Alan's CLE Information Section, http://www.ndblist.info/cle.htm
    CLE107 was our last CLE rather like this one - way back in July 2008!

    Good listening

    (Reminder: If you wish you can use a remote receiver for your loggings,
    stating its location and owner - with their permission if required.
    NB: THAT RECEIVER must be located within 2 hours of ‘real’ midday.
    A remote listener may NOT also use another receiver, whether local or
    remote, to obtain further loggings for the same CLE).

    These listening events serve several purposes. They:
    • determine, worldwide, which beacons are actually in service and on-the-air so the online database can be kept up-to-date
    • determine, worldwide, which beacons are out-of-service or have gone silent since the last CLE covering this range
    • will indicate the state of propagation conditions at the various participant locations
    • will give you an indication of how well your LF/MF receiving system is working
    • give participants a fun yet challenging activity to keep their listening skills honed

    Final details can be found at the NDB List website, and worldwide results, for every participant, will be posted there a few days after the event. If you are a member of the ndblist Group, results will also be e-mailed and posted there.

    The very active Yahoo ndblist Group is a great place to learn more about the 'Art of NDB DXing' or to meet other listeners in your region. It's also a good place to submit your CLE log! There is a lot of good information available there and new members are always very welcome. As well, you can follow the results of other CLE participants from night to night as propagation is always an active topic of discussion.

    If you are contemplating getting started on 630m, listening for NDBs  is an excellent way to test out your receive capabilities as there are several NDBs located near this part of the spectrum.

    You need not be an ndblist member to participate in the CLEs and all reports, no matter how small, are of much value to the organizers. 

    'First-time' logs are always VERY welcome!

    Reports may be sent to the ndblist or e-mailed to either myself or CLE co-ordinator, Brian Keyte (G3SIA), whose address appears above.

    Please ... give the CLE a try ... then let us know what NDB's can be heard from your location! Your report can then be added to the worldwide database to help keep it up-to-date.

    Good hunting!
