Hi All

Yes - CLE126 !!
During the Holiday Noah CLE, No.125, we shall be listening on all our usual frequencies at all times of day and night.  That will also give us an opportunity to spot beacons which have technical faults of various kinds and maybe to seek out ones that we already know about.  It is an add-on 'extra', to be treated as a separate CLE which you can also join in if you wish.

   Days:     Friday 25th December to Monday 4th January
   Times:    Start and End at midday, your LOCAL TIME
   Target:   Beacons showing technical faults
                Only 'Normal' NDBs please, not Amateur, DGPS or Navtex
   Range:    190 - 1740 kHz

We'll be looking for any examples of the following fault types.  
You will probably only hear examples of a few of them:

Include a MAXIMUM of THREE examples for any of the following kinds of fault.
Specially good examples would be cases where a fault is easy to detect and has probably lasted for quite a long time.

   K:   NDB with a keying fault, not sending its intended ident
   C:   NDB whose carrier is significantly off its nominal frequency
   O:   NDB whose offsets from the carrier are significantly different from its nominal ones
   M:   NDB with a very low (or zero) modulation level
   N:   NDB with negative keying (the tone is heard when there should be silence and vice versa)
   Q:   NDB sending a 'quizitive' ident in addition to the intended one  (this is a rare condition
          mainly of a few British beacons with RAF connections - listening very close to the carrier,
          a rough 'grumbling' Morse-like tone is heard)
   S:   NDB sending extra, spurious sidebands (offsets)
   T:   NDB with a rough (poor quality) tone
   D:   NDB whose carrier frequency is drifting
   G:   NDB whose gap between its idents is too short, so the start letter is uncertain
          (e.g. is it ABC, or BCA, or CAB?)
   A:   NDB with an ambiguous ident - e.g. 'EE' which might be misread as 'I'.  (not the same as K above)
   E:   NDB sending an emergency 'E' (standby TX) after the usual ident. (not strictly a fault)

   X:   NDB with any other fault condition not in the list - please explain what it is - e.g in a footnote.

Please give the usual log details - date, UTC, kHz and intended Ident, etc. -
and show the fault type letter (just a K, C, O, - - - , or X) at the RIGHT HAND END of every log line.
You could add any further details in a footnote if necessary.
IMPORTANT  Please do not attach a sound or picture file to your log - use a separate email if you want to do that. (I still have only slow dial-up and an outdated PC and I may not find logs in large emails).

Send your log (Subject: CLE126 - -  ) to the List (in Plain Text if you can) to arrive by 09:00 UTC
on Wednesday 6th January at the latest. Please keep your CLE126 'Fault' log separate from your
CLE125 Noah log.  (You could include the same logging in both your logs, if it qualifies for both,
and if any beacon shows more than one fault you could repeat the logging with a different letter).

I'll send an 'ANY MORE FAULT LOGS?' email on the Tuesday evening listing the CLE126 logs that I have found.  

Our results will provide useful seeklists, so that newer listeners will be able to hear for themselves good examples of many of the fault types.
My special thanks to Alan, Dave, Peter, Roelof and Steve for the help they gave me in preparing the list of faults.  


A very Happy Christmas to all - and Good Hunting.
   Brian
