Friday, May 19, 2017:  Mark attended the annual Radio Daze gathering in Plymouth, MN, sponsored by the Northland Antique Radio Club
One hundred or more antique radios were on auction that weekend.

Mark liked an RCA ribbon microphone from the 1950s.  He was also impressed by the early 1950s television set with a round screen.

The auction went on with aggressive bidding.  Many people went home with radios that are darn near 100 years old.

The next morning, Mark was off to a meeting of the Quarter Century Wireless Assocation
It is for those who were first licensed as amateur radio operators twenty five or more years ago.
A presentation was given by Jim Othout, WB0KZB, on how to install amateur radio transmitting equipment in a car or truck.
There is a lot to learn if you are interested enough to become involved.

Back at the antique radio gathering, a very nice display of twelve crystal radios won first prize in its category. 
For those who do not know, crystal radios dtate back more than 100 years. 
They do not have a power source except for the radio signal they are listening to. 
Consequently, they are not very sensitive and can only power an earpiece, but not a loud speaker. 

There is an interesting portable radio from the 1950s.  Note that the AM radio dial went from 550 to 1600.
The band now goes from 540 to 1700 Kilocycles, now Kilohertz. 
The name change is in honor of Heinrich Hertz, a German physicist in the late 1800s.

Best of the show was this 1935 Scott Guaranta receiver.  Wow, it cost $2500 back then.  That is $45,000 in todays money. 

And there was Nipper, the RCA dog, listening to his master's voice.

An early television set from 1948.  Most smart phones today have a larger screen.   

A talk was given by Steve Raymer of the Pavek Museum of Broadcasting.  A nicely done history lesson. 
Here he is showing a three tone chime used by the NBC Radio Network for years.  

Quote of the day:    Radio has always fascinated me.   Mark    < Back to previous story Ahead to next story >
