Signal Electric Mfg. Co.

R-68 Wireless Practice Set

Manufactured Early- to Mid- 1930's

(The following description is taken from the "Fundamentals of Wireless Telegraphy" booklet included with their practice sets)

"Designed for those who want a well made instrument to learn the code.  Set consists of a key and high frequency buzzer mounted on a mahogany finished wood base equipped with binding posts.  The code is printed on a plate and fastened to the base between the key and buzzer.  Buzzer is adjustable.

List $3.00"

Front View

The large round object on the left side of the wood base  is the buzzer.  Behind the buzzer are three binding posts, and between the buzzer and the key is a brass plate, showing a visual representation of the International Morse Code, using "dots" and "dashes" to represent the "dit" and "dah" that make up the sound of morse code. 

 Note that it is now generally accepted that learning morse code by seeing it is a bad idea - learning that way will hinder your ability to listen to and recognize - or "copy" - morse code beyond a few words per minute, which is very slow.  To copy code at a comfortably usable rate - 30 words per minute or even 40 plus words per minute, you need to learn the code by hearing the sound and rhythm of the characters, numbers and special abbreviations and characters called prosigns.

Here I removed the cover from the buzzer.  Notice too that there are three binding posts; the third (middle) post was for connection to a second practice set so that the users could practice both sending and receiving morse code with each other.

Bottom View

The bottom of this key still has the original rubber pads in the four corners, however by now they are hard and allow the key to slide around the desk making it difficult to send morse code.  You may just be able to see where I added new clear pads so that I can use the key without it getting away from me.

The piece of paper attached to the bottom is the instructions for attaching the dry cell batteries, and for connecting two keys together.

Seeburg - "Stereo of the Stars"

I call this my "Seeburg" key, but I have no idea what it is.  If you know, please email me!

Front View

I have no idea the history of this key.  I have no idea if it was a marketing piece from Seeburg, or if some industrious ham put this together.  The key is an inexpensive, but functional, Japanese ball-bearing type key, similar to those marketing by AMECO.

The round plaque says:







MFJ - 564 Iambic Paddles

This is my first set of paddles. Inexpensive, functional, and a lot of fun.

Front View

This key, or Paddle, has no significance other than it is my first set of iambic paddles, and is what I'm using most now.

Paddles require an electronic keyer, and my Elecraft K1-4 has a keyer built in.  For radios without one built in, such as my Kenwood TS-130s, I built a PK-3 Keyer Kit from Morse Express.
