Also during WW I. In fact, at the end of WW I, the Navy (who controlled all radio) did not want to give it back to the public, neither for amateur or commercial use. It took the weight of companies that would become Westinghouse and RCA to push the the government toward entrepreneurial broadcast radio. Reception selectivity was a problem with early radio, and the Navy worried that casual and business use would interfere with their own operations, and also that of commercial shipping, who the Navy planned to license. 2-way was all they thought of. Broadcast (to many) was considered to have only a small and unrealistic business case. Even Marconi was cool toward broadcasting. But David Sarnoff saw the opportunity.

And people thought the Patriot Act was draconian.It seems the pendulum has swung back and forth since the start.

It's amazing what Americans put up with 100 years ago. I first heard of The Four Minute Men in a book on the Great Influenza of 1918. You could hardly go to any public place, from a movie to a school board meeting, without being barraged by one of them. Read the marching orders for these propagandists in this chilling piece: historymatters.gmu.edu/d/4970/ |

Hmmm, a propagandist's guide. I like it.

Yea but unlike the Internet or cell phones, where the government can flick a switch and shut down communications, the only switch that can be flicked on armature radio is the power button on my new 2 Meter Radios.

Dave I have Skype but don't understand this post. Is it for communication with a shortwave. Your url only brought me to the Skype sign up page. Can you clarify this for me.  |

Well, you know what Skype is ... telephone over Internet. I have used it to communicate PC to PC with a friend in Marcy. Another friend in North Carolina uses it to talk to her daughter in Africa. If you keep it PC to PC, it's free after you sign up. There are charges involved when a regular telephone is involved. The info on the Medium Wave Cluster came to me from a Yahoo group I haven't checked in a long time, and I don't remember how to sign on the Skype cluster. I'm still in the group, but had turned off emails. I'll get back in and post a query on the group ("ammediumwavedxing"). After you log into the Skype Cluster, you just sit back and wait for someone to say, e.g., "I'm hearing Station X in City Y here in City Z loud and clear, with some fading." And of course, there are regular DX clusters that appear in list form on the Web. Here's an example from the Ham world. CLICK ON: www.dxwatch.com/How to read it: The first two columns are the call letters of the two hams in contact with each other. The ham in the first column "de" is working what to him or her is DX in the second column, on the frequency in the third column (in megahertz), with observations or comments in the fourth column, on the time and date noted in the last column. I just posted a note on the ammediumwavedxing group asking how to log on to the Skype cluster and will let you know. |

Maybe for the benefit of others reading this, I should also say that DX means "distance" and radio folks are always interested in how far they car hear, and hams are interested in how far they can "work," or exchange two-way radio transmissions with another station. A DX Cluster is a listing or posting of what DX is heard on the radio. E.g., you might hear hear WLS coming in from Chicago in the evening ( pretty easy here in the Northeast), so you post it on a list that everyone else can see. That's called a DX Cluster ... a cluster of people exchanging info on what they're hearing. In ham radio, info includes who you hear working who when it occurrs over large distances.
Without access to a DX Cluster, for example, I might never know that Argentinian stations have begun to come in on the 60 meter band (below 5 Megahertz shortwave) for the first time in months. Logged in to a cluster, I can keep track of worldwide radio conditions.
Medium Wave is what "normal" people call the AM Broadcast band, roughly 530 to 1710 Kilohertz. Stations easy to hear at night in the Northeast (once you turn off the dimmers and other noisemakers) are in Boston, Washington, Chicago, New York, Charlotte, Toronto, etc.

Okay so then if you plug into a cluster on Skype is it listening to others sort of like a conference call. Are you able to type each other messages also.
