KPH is silent on maritime frequencies, but through the hard work of volunteers continues operation 24/7 with a 3-30MHz KiwiSDR receiver (http://188.8.131.52:8073/) and various activities throughout the year. Full information on all things KPH can be found the excellent Maritime Radio Historical Society Website (http://www.radiomarine.org/).
Finally an excellent “Bay Area Backroads” episode about KPH is available on Youtube:

The Frequency of the HF broadcast is directly assigned within the DRM+ SDR app with two settings
1. Frequency in Hertz
2. RF Gain (0-512)
Demonstration video showing Clean DRM decode of AAC Audio and Journaline data along with live metadata. (our signal was very strong, so only a short wire used for Antenna, DX’rs will need an appropriate Antenna)
Now anyone with a smartphone and a $20 SDR can receive DRM 30 HF broadcasts…
The three letters – QSL – constitute one of the codes originally developed in the days of the telegraph. All codes consisted of three letters beginning with “Q”. Later some of these “Q” codes were adopted by radio-telegraphists and radio listeners. QSL means “contact confirmed” or “reception confirmed”.
The expression “QSL card” or just “QSL” gradually came to be used among radio-amateurs and then more broadly as radio began to develop as a mass medium. Radio stations were keen to know how well and how far away their programmes could be heard and began to send their listeners “QSL cards” in return for reception reports. The card would include letters making up the “call sign” of the station – the system still used in the United States – or the broadcasting company’s logo or some other illustration. The card would also include a text stating the frequency and the transmitter output power, and a confirmation of when the listener heard the station.
Domestic broadcasters do not tend to use QSL cards these days, but their popularity remains among radio stations broadcasting internationally. They are still keen to know how well they can be heard in the parts of the world to which they broadcast. In the era of shortwave broadcasts Radio Prague sent out QSL cards for reception reports received. After curtailing our shortwave transmissions as of February 1, 2011 we will continue issuing QSL cards for reception via the Internet.
Here you can look through our current and past series of QSL cards:

Users of these two propagation prediction programs will find that they don’t work beyond Dec 2019 because the SSN look-up files didn’t go any further.
I noticed this 2-3 years ago and added to the end of the files required. I entered guesses for solar activity values, but with auto mode turned on they will fetch current values. At least this will get you started again. Or my guesses might be right!! 🙂
Many thanks to SWLing Post contributor, Harald (DL1AX), who shares the following message from the Southgate ARC:
