RTTY KPH Baudot/Sitor-B is back on the air

[ka3jjz]

I don't know if this is still going on (I just saw this), but this comes from Richard Dillman (from the Maritime Radio Historical Society) on the UDXF reflector...

KPH RTTY service is on the air with Baudot (45 baud 170Hz shift) to be followed by SITOR-B (FEC) on

6324.5
12585.5

8427.0 may be heard later today during antenna tests for this frequency.

In the future if you see posts like this earlier than I do, please post it immediately

Thanks

Checked a kiwi sdr in Ohio and sure enough they were there.

For those that may not know; SITOR-B. AMTOR mode B, FEC, SITOR FEC and even NAVTEX basically are all the same protocol. So any decoder that uses these names will work with the above transmission

For those of you with radios that can decode Baudot RTTY natively - you won't be able to handle SITOR-B the same way. Fortunately there are numerous software options for this mode listed here

SITOR-B - Signal Identification Wiki

SITOR-B is one of two modes of SITOR (Simplex Teletype Over Radio).

It's Saturday, but I can't hear KFH on any of their listed frequencies. KFS on 12695 kHZ CW is coming in, but very weakly. K6KPH isn't showing up on 14050 today, but then that frequency is currently in use by contest participants. Before the pandemic I was hearing KFS on most of their CW frequencies, and especially strong on 12808.5. The last time I picked up any of their RTTY and Sitor B broadcasts was perhaps 3 or 4 years ago; can't hear them now. Neither my receiver nor my antenna have changed since then.
