Channel 1 is a fed govt tv channel.(Correct me if I am mistaken about that) If or when the s..t hits the fan big time,that is the only tv channel that we can get on our tv sets. cuhulin Channel 1 has never actually existed. It was originally a designated television channel, but was done away with and given to other services before television ever actually started broadcasting (48-50 MHz is VHF low band public service frequencies (police/fire/ambulance) and cordless phones, baby monitors and other Part 15 devices. 50-54 MHz is the Amateur 6 meter band. |

I think the problem with channel 1 had something to do with skywave interference-channel 1 easily bounced off the ionosphere and caused interference in the form of one channel 1 station interfering with another one a thousand miles away. That can happen above 54 Mhz, but the conditions are more rare, such as E Skip. There were actually 2 or 3 licensed channel 1's, and a number of early (1945-47) TV sets were made with channel 1-I once owned an Airline (sold by Montgomery Ward) TV made in 1947 or so that had channel 1. That particular set was actually made by Hallicrafters. I believe there is a Channel 0 in Australia-can anybody confirm this? |

I own an old General Electric table model tv set I bought for $5.00 at a
Salvation Army thrift store about five years ago.The tv set was manufactured in 1957.I just now went to one of my junk rooms in my house and I took a look at it.The tv channel selector knob does have channel 1 on it. cuhulin |

Among other reasons. Channel 1 was designated as a "community channel"; stations operating on this channel were limited in power. *All* the TV channels were shared with other two-way services - the sharing didn't work very well, and it started at the bottom end of the spectrum - i.e., in channel 1. I don't think any channel 1 stations ever actually operated, but at least one (in Riverside, California) did receive a permit. by Hallicrafters. I believe there is a Channel 0 in Australia-can anybody confirm this? There is. http://www.w9wi.com/articles/system.htm#systemd.htm , it's at 45-52MHz. My information is that channel 0 is being phased out, if it hasn't already been deleted. Australia also has a channel 1, but it's 56-63MHz, roughly equivalent to channel 2 in the U.S. In general, channel numbers outside the Americas correspond to different frequencies than what we use here. -- Doug Smith W9WI Pleasant View (Nashville), TN EM66 http://www.w9wi.com |
