Continental Code vs. Morse Code



According to w2csl, Bob, what we now know and use as Morse Code was originally called "Continental Code". It was an upgrade from the first Morse Code that was developed in an effort to standardize code with other countries.

The picture shown above was found by David, my most recent AT&T U-verse installation tech. Dave responded to a call for help from me after I moved my computer back into our "office" from a recent remodeling fiasco.

We had AT&T out about two months ago to put in another Internet drop. The tech that responded then added a line to a temporary location in the house. He did not wire it into the system, but told Jim, our tile installer, how to wire it in when we're ready. So when we moved the computer from the office into our den, we just had to splice in the new wires. That tech told us that we could just leave it that way when we moved back to the newly tiled "office". When we did move (eventually) back into the office, we could not get the internet back up.

David showed up and found that the, now unused, temporary wiring still hooked to the system acted like an antenna and allow enough noise into the system that the signals would not sync in. Our 3-in-one package left us without TV, internet, and phones. All David had to do was disconnect the unused pairs and the system popped back up.

David noticed some of the HAM paraphernalia in the office and we talked a little about it. David mentioned that he had found a handwritten table of Morse Code vs. Continental Code inside a 1901 printing of Longfellow's Poems, brittle from age, which he bought at a garage sale.

David scanned the old document and e-mailed it to me. That is it pictured above.

A teeny bit of code history.

Tech Net Notes October 30, 2009


We didn't get very far into the tech net before the repeater went Ka-bloooey. During a transmission the repeater timed out...and that seemed to have done something to disable it's operation.

Thanks to those who tuned in...or at least, tried to.

Sorry, we'll give it another shot:
November 11, 2009 - 146.910 - 7:00 PM
November 27th, 2009 - 147.045, 443.850 & linked system - 9:00 PM

Enjoy the weather!
