How did old radio work?

How did we get the "Grand Ol Oprey" on the radio in the old days? Was that through telephone lines, pre-tape or what, I don't think there was satelite transmission back then. I'm curiuos.

AM radio waves tend to 'skip' off the inside of the atmosphere (ionosphere I believe) and bounce back to earth at the same angle that they hit it (angle of reflection equals the angle of incidence)...

This is how we used to be able to hear stations like WWVA (Wheeling, West Virginia) all over the nation, but predominantly north and south of VA...The signal actually bounces around the curvature of the Earth using the atmosphere as a mirror...The signals always got stronger after the sun set too, as the sunlight tends to scatter the waves in the ionosphere due to high energy movement of the molecules...Heating matter makes the molecules move faster...

Was a big deal when I was a kid to add a linear amp, directional antenna, and a power mic to your CB base station and talk 'skip'...Don't be dumb enough to use your call letters though...The FCC really frowned on it...

There are still people out there doing it...Still illegal as all get out on certain frequency bands...

Like stated above- E layer reflection of the radio waves. The shortwave is best on high frequencies during the day & low frequency plus longwave (same as US AM radio) is best at night.

Some have a hobby as SWL (short-wave listening). One can get both sides to news stories as shortwave travels around the world for the most part (foreign broadcasts). US AM longwave frequencies are more local to the US.

I am a Ham Radio operator. My call is N8FVJ.

Speaking of remote controls , I`ve been shoping for a window air conditioner . They all have remote controls !!! What do I need remote control on a air conditioner for ?!?!?!

Actually our new window fan has a remote and its kind of handy in the middle of the night when I wake up cold. Just snag the remote of the nightstand and shut 'er down.
Same works if I wake up too warm too.

Good question ! I can't believe that, maybe some one had a relative in the "dream up" division of that industry that needed to push their idea !

Most broadcast net works had radio transmission systems for transmission and rebroadcast of syndicated and other national shows. I grew up near Hershey PA and could get WOWO in Ft. Wayne, Ind and CKLW from Windsor Ont. Once in down town Miami Fla, I got WABC from New York City. All over the Airwaves to the am radio in my 1970 Mercury Montego. There were higher radio bands dedicated for this type of transmission and rebroadcast over regular fraquencies. My dad would always listen to the ole'Oprey when we were traveling. Can't say I remember much more than Grandpa Jones and Minnie Pearl. In 1990 I actually went to the Oprey. Even though I wasn't a CW fan, it was worth doing. I got to see in person some of the country greats, Chet, Minnie, saw Roy Clark and several others.

You get a radio out of a 49 Buick,They had a good sound.( for those days..We thought,,,)


Burrhead    Posted 06-14-2003 at 19:01:06       [Reply]  [No Email]
They did have a good sound. My 51 Roadmaster even had 2 factory speakers. About 4" each on each side of the dash board.

Never figgered out why they put the radio on the ceiling and the speakers in the dash.

Then you remember,The Buick was the only one(I know of) That had a knob at the roof to turn the radio ariel sideways so you could get into the garage?My dad often had a Buick because he liked the straight 8 engine and Dynaflow automatic trans.I remember the 51 Buick he had.You stomp the accelerator to the floor and that made a starter button work.Eventually the spring got bad and accelerators hung.If you panicked and forgot to urn the key off when it hung going down a crooked dirt road you were in big trouble.My brother forgot and wrecked the Buick by running into a creek.So when my turn came to learn to drive I had the choice of a 55 International pick up.The exciteing think on that was my friends and I thought it was fun to pull the throttle out and run along side of the pickup and one hold the steering wheel.Kids do dumb things.

10-4 on the antenner knob and the starter. Never had a car shed but the antenna would clear when it was parked in the hall of the barn

They did'nt have a *Park* position for the gear shift. To lock it down to park you cut the engine off and moved the gear selector to reverse position.

I didnt know they had park gear missing.My dad had a 39 Buick ,it looked like a new one.The back doors opened into the wind.My crazy cousin #2 puled the handle going forty MPH on a highway when he was a small kid.He skidded forever.The guy behind was a WW2 fighter plane pilot so he dodged the crazy cousin #2 ,,and the kid was only skinned up a bit but lost a lot of hair on his head.I remember holding his finger untill he dropped away,I jumped up and looked out the back window and saw him skid.
