Spark Gap Transmitter

The Old Spark Gap Transmitter

Are you interested in antique radios? Really antique radios? If yes, then perhaps you can help ARCUA identify our Spark Gap Transmitter.

Please help us identify this rig. We believe it dates from the early part of the century. The University of Arkansas was first licensed as 5YM in 1916 and may go back as far as 1900.

It appears that it was assembled from components (what wasn’t back then?). If you can give us hints or clues to the age and/or origins of this piece of history, please email w5ym@uark.edu.
