KC2 Keyer/Freq. Counter/S-Meter/Wattmeter

The KC2 is a unique multi-function transceiver accessory. Despite its small size and low current drain it offers an Iambic keyer with message memory, 4-digit LCD frequency counter, bar-graph S-meter, and a digital wattmeter. The KC2 does not require a keyer paddle for configuration; four pushbutton switches are used to configure and control all KC2 functions. This allows the KC2 to be used with SSB as well as CW transceivers.

Most counters and other digital accessories use a 4Mhz or higher crystal clock frequency. If left unshielded, these units--particularly those with LEDs--may generate loud spurious signals that can be heard at many places in the tuning range of the receiver. In contrast, the KC2's microprocessor runs at a much lower clock speed--only 100kHz. In combination with a liquid crystal display and CMOS logic, this makes the KC2 one of the few digital accessories available that offers near-zero receiver noise. Even on a quiet band, the KC2 can be left on at all times.

While the KC2 was designed with the NorCal/Wilderness Sierra and NorCal Cascade transceivers in mind, it will work with many other rigs as well. If you use the KC2 with a rig not presently mentioned in Appendix E, please send us the details of your installation so we can include it in a future revision of this manual.
