Learning Outline

The keyer supplied with the TS-870S is a full-featured K-1 Logikey keyer that will delight anybody that respects a good keyer. A great deal of information on using this keyer is provided in this manual, not because it is difficult to use, but because it has an incredible number of features. Some of the features of your keyer include:

¥Iambic operation with dot and dash memories

¥Programmable via commands sent from your key

¥Emulation modes for other keyer types Ñ you wonÕt have to re-train yourself if youÕre used to a keyer with different timing

¥Soft-sectored messages that can ÒcallÓ each other and can contain embedded functions

¥Automatic contest serial number generation

¥Digital and linear speed control (6 ~ 60 wpm)

¥Adjustable weight for code elements (25% ~ 75%)

¥Tune function for continuous key down

¥Selectable automatic character spacing

¥Message loop capability for continuous replay

It is probably best to learn the keyerÕs basic functions first, then use it on-the-air. Over time, you will build up your knowledge of its operation bit by bit. DonÕt try to memorize everything at one time!

Points to know before beginning:

¥Although the sidetone can be heard while using any mode, CW mode must be selected to set functions on the keyer.

¥When pressing two or more keys on the keypad to select a keyer function, press the correct keys as instructed, then release them. You know youÕve held them down too long if you hear a continuous tone before releasing the keys. In this case, a rapid multi-dit error alarm sounds when you release the keys to confirm the error.
