[. . . ] MICRO MEMORY CW KEYER
THE KEYER THAT NEVER FORGETS
Ramsey Electronics Model No.
CW-700
Now you can send perfect quality code at any speed!This computerized "smart key, " for novices and pros alike, even lets you store your own personal messages for a fraction of the cost of other keyers!· ·
A state of the art microcontroller lets you send perfect quality code anytime, at any speed!Four memory banks allow you to record your own personal messages for up to two minutes long. [. . . ] Install R20, 1K ohm resistor [brown-black-red]. This resistor must be mounted "standing up. " (Boy, if those resistors didn't have such strong legs, you might open your kit up some day and find them all laying down on the job. ) 44. Install R32, 1K ohm resistor [brown-black-red]. Make sure that this one stays standing up also. Install C13, another 10uF electrolytic capacitor. Be sure to pay attention to the polarity. You have now completed the power supply for the microcontroller chip. You have also completed the circuit that determines the speed of the code. Please check for bad solder joints and insure that all of the parts have been inserted correctly. When you return, you will be building a circuit for the memory chip first. Then, you will be building the circuit that makes the tone that you hear, and it's volume control.

46. Install R29, a 10K resistor [brown-black-orange]. Mount this resistor standing up too, please. Install R30, a 470 ohm resistor [yellow-violet-brown] standing up. Install R31, a 470 ohm resistor [yellow-violet-brown] standing up. Install R16, a 47K ohm resistor [yellow-violet-orange] not sitting, but standing. Install R17, a 2. 2K ohm resistor [red-red-red] standing. Install C7, a . 1uF disc capacitor [marked . 1 or 104]. It will be small, orange, and marked "502. " Press the potentiometer flush with the board and solder all three connections. This part will let you adjust the pitch of the tone. Install D10, a 1N4148 glass bead diode, paying particular attention to the way that the band is pointing. You have now completed the circuit that makes the tone that you hear. [. . . ] NOT be assembled with acid core solder or flux. BE returned in fully-assembled form, not partially assembled. BE accompanied by the proper repair fee. No repair will be undertaken until we have received the MINIMUM repair fee (1/2 hour labor) of $18. 00, or authorization to charge it to your credit card account. [. . . ]
