Morse Code / Re: Can Morse Code Still Save You?

Jack Binns was awakened by a tremendous crashing sound, screaming metal and a shudder that ran through the ship. As the wireless operator, Binns knew immediately what to do. Fortunately his long-wire antenna was still up and he had backup battery power. Jack started sending CQD on his spark-gap transmitter, ultimately saving four thousand lives from his ship, the Republic, and those of the Florida, the vessel that hit them in the fog. It was on January 23rd, 1909, and the first significant use of Morse code to save a great number of lives at sea.

Nice article, however this introduction is too short, in a way. As I know well from several years in the profession, a radio operator cannot just go ahead and send distress signals without the ship's Master ordering him to do so. That was probably a rule in 1909, too, as confirmed by a contemporary news article:

And "saving four thousand lives"?
https://en.wikipedia.org/wiki/RMS_Republic_(1903)   — 1,500 lives saved.
https://de.wikipedia.org/wiki/Florida_(Schiff,_1905).  — 900 passengers transferred to the Baltic. (The Florida did not sink.)

Also, it seems the whole story was more complicated and perhaps a little different from the summary above:

(PS - make sure your aerial isnt plugged into any kind of distribution system (active or passive) in case you pick up some nasty voltage or static that fries your radio)

I would also worry about myself frying my neighbours' television sets or radios that may be connected to that distribution system, which was the case in the apartment building where I live, with a huge antenna on the roof.

(That's history now though, in my case, because radio, TV, and broadband Internet come into the apartment from an underground cable which, obviously, cannot serve as an emergency antenna.)

For Preppers, the Apocalypse Is Just Another Disaster

The prepping movement has a bad image spurred by right-wing extremists. But preppers are a largely misunderstood bunch.

* WinPCC-Sark100.exe.7z  Downloaded this file but my Winrar is reporting the file is corrupt. :( Anybody having the same issue. ???

I am on a Mac and cannot really do much to help. The file downloaded OK, but cannot be opened on a Mac. Try removing the suffix ".7z" before opening, so your PC understands it's a .exe file may help.

Quote from: CroPrepper on March 02, 2018, 08:48:52 AMI also read somewhere the 817 has a built in antenna tuner ...

Are you certain? If that is so, why did my ham radio vendor insist I needed this one?

I show here two of the best radio receivers made during WW2.
E52b and Lo6K39a.
Lo6K39a is probably the world's best TRF receiver.
E52b is the best receiver made during the war.

BTW - is there a place to look up SW transmission information? That is a list of transmitters on the air.

There certainly is! I bought my very first edition of this outstanding book some 55 years ago:
