14080 is a hangout for those of us that do Hellschreiber. You may have seen one
of the Hellschreiber versions.
One of the modes (FeldHell) looks like a wispy vertical bar with horizontals
sporadically through it. Obviously this isn't the one
you saw
More likely is the FM105 or FM245. These do look like narrowed rtty bars. This
mode is exceptional for long distance Hell.
(There are other variants but I've not tried them)
If you don't already have it, try MIXW as it has these modes (free download
trial copy -- do a quick search of the web. Free version
fully functional after trial period but changing modes becomes very tedious --
registration is cheap)
Best regards

PS if you want to give it a try some time, let me know and I will setup a
schedule. (Oregon qth)

Scott, et al,
It is not MFSK16. I have a decoder for that which I sometimes use. You can
hear the shifting tones in MFSK16 and see the tones moving around on the
MMTTY display. I don't know what BPSK16 sounds like but one the MMTTY
display it looks to have only several tones but the baud rate is much
higher then rtty.
Interesting
Jerry,
