Hello all Here are the full details for this weekend's Co-ordinated listening event. It is open to everyone including CLE new-comers: Our 309th CLE starts this Friday. We'll be listening for up to 8 NDBs in as many Locator FIELDS as we can. Each Field is the first 2 letters of a 6 character locator ('Grid Square'). A World map of all the locator Fields is attached. Days: Friday 25 October – Monday 28 October Times: Start and end at midday, your LOCAL time NB: Most of us are changing our clocks by one hour this weekend. However UTC time (as shown in our logs) continues unaffected. Range: 180 - 1740 kHz Target: Up to 8 normal NDBs in each Maidenhead Locator Field (not DGPS, NAVTEX, Amateur or UNIDs) Please join us wherever you are - just log up to 8 NDBs that you can positively identify in as many Locator Fields as you can. Please include your nearest active NDB (likely to be one in your own Locator Field). Send your final CLE log to the List, preferably as a plain text email (not in an attachment) with 'CLE309 FINAL' in its subject line. Please show on EVERY LINE of your log: The Date (e.g. '2024-10-25', etc., or just '25' ) and UTC (the day changes at 00:00 UTC). kHz (The beacon's nominal published frequency) If you don’t know it, please visit https://rxx.classaxe.com where you will find all the details. The Call Ident. Show those main items FIRST on each line, before other optional details such as Location, Distance, etc. Please don’t forget to add your listening location (the 6-digit Maidenhead-Locator) for either your home location or the remote receiver you were using during the CLE. Also, if you use a remote receiver which is publicly available, please give the web-address for it. Your log will be easier to read if you group your loggings by Locator Field and leave a blank separator line between the groups of up to 8 lines for each Field. If you wish, you could add the 2-letter Field ident (NOTHING ELSE) at the start of each of the separator lines. Always make your log interesting to everyone by giving further details of your listening location and also of the receiver, aerial(s), etc., that you were using. You could listen from home or, if you prefer, via a chosen remote receiver. If you send any interim logs during the event, please also send your 'FINAL', complete, log. We will send the usual 'Any More Logs?' email at about 19:00 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 30 October. We will then hope to complete making the combined results within a day or two. You can find full information about current and past CLEs from the CLE page at https://www.ndblist.info/cle.htm . You can also find your relevant seeklists made from REU/RNA/RWW by visiting https://rxx.classaxe.com/cle . In case of any questions you can contact us either via the list or Direct to the Coordinators using email address ndbcle@ndblist.info. PLANNING YOUR LISTENING It will really help you to plan your listening using the excellent Rxx Database : https://rxx.classaxe.com THE KEY PLACE to start entering details of what you want is ‘Signal Details’ – ‘Grid Squares’. Put a 2-letter FIELD id in that box and click on “Go” to see all the NDBs in that Field that have been logged from your part of the World (i.e. EU or NA or other). You can even search for signals in multiple Fields by adding extra locator Field(s) in the 'Grid Squares' box, separated by blanks. Getting cleverer (!) you could use the wild card _ (an underscore) to see details of all Fields with the same column of Longitude or row of Latitude e.g. I_ selects all of locator column “I” (0 to 20 degrees west), _O selects all of locator row “O” (50 to 60 degrees north). Good listening Joachim and Brian (CLE Coordinators) Reminder: You could use any ONE remote receiver for your loggings, stating its location and owner - with their permission if required. A remote listener may NOT also use another receiver, whether local or remote, to obtain further loggings for the same CLE. World Locator Fields Map1.jpg
