Author Topic: Strange signal on 14082  (Read 3093 times)

Can anybody ID the strange signal on 14082 kHz LSB?  It sounds like a harmonic of some sort.  The signal consists of 3 to 5 groups of extremely fast Morse dits with even spacing between groups.  Kind of like a burst data mode.  Any thoughts?

Steve,

Did you happen to catch the signal as a .wav file that you could post?  John Becker M5AML reported a strange signal several days ago and he posted this MP3 file on the DigitalRadio eGroup (www.qsl.net/m5aml/18.101MHz.mp3).  Does your signal sound like this one?  If so it may be an ionosonde probing the ionosphere.

Nope, that's not it.  I'll catch it and record it.  The signal seems to always be around 14082 LSB when I hear it and sometimes I can hear a faint station perhaps answering??  It sort of reminds me of splatter from a Pactor signal, but the pattern is different than Pactor, and sometimes when I hear it, there are no Pactor stations on....

I'll post a recording.

Nevermind!  It was just a Feld-Hell signal...believe it or not, that's the first one I have ever heard.

Hell modes (hellschreiber) used to hang around 14.061 USB or so, but since MixW included it, I have seen most activity around 14.079-14.082 USB.  If you want to see what it's about, I would suggest Griff's (NB6Z) website which has a lot of great info and some .wav files of most of the HF digi modes.

After calling CQ a couple of days on 14063 USB running HELL FELD I moved up to 14078 USB carrier offset 1000 hz and found others running HELL FELD mode.  This is a real fun digital mode.    It is a digital mode with eye-brain combination of forms sort of paints the signal across the CRT in a double line.   Do a search on fuzzy modes and you will be able to locate a copy of the program or run MIXW2.
