[GreenKeys] early automatic Morse to Baudot equipment?

[Harold Hallikainen]

I am so used to copying CW by ear, I can't imagine reading it off a tape
and transcribing it. I've seen an inked tape recorder at KPH in Pt. Reyes
Station CA. Also, at the Telecom History Group here in Denver, there's an
inked tape recorder for fire alarms.

Machine translation of Morse is interesting. The Reverse Beacon Network
seems to do a great job. I will often get 25 or 50 hits on a single CQ
call (like this:
http://www.reversebeacon.net/dxsd1/dxsd1.php?f=0&t=dx&c=w6iwi ). There's
also a Morse decoder in the KiwiSDR (like the KPH one at
http://kphsdr.com:8074/ ), but it gets a lot of errors. Operating it, it
looks like anything above a certain receive level is mark, and everything
below is space. Noise often goes above the threshold (which is adjustable,
but if you set it too high, you get errors during a fade) causing errors.
By ear, we can tell the difference between tone and noise. It does not
seem to be able to do this. So... need to send CW using FSK!
