This Kit Has Been Retired

This full featured PIC-based iambic Morse code keyer features 3 memories and very easy use. It has many of the features of the high end keyers while maintaining ease of use. The PIC chips have been programmed by Craig Johnson, AAØZZ, of PIC-EL fame. Commands are entered directly rather than scrolling through menus.

Using a PC board that is only 1.5" x 1.75", this is an EZ-to-build small footprint project with large impact on your operating capabilities, whether in the shack or in the field. It is Altoids® tin compatible, and installation instructions are included in the assembly manual. 4SQRP Group provides sample Altoids® labels in separate PDF files. Please refer to the photo page to see how your Altoids® tin installation might look. And check out the nifty labels for your favorite mint tins.

The kit includes all the parts required to build the kit - push buttons, connectors, speaker, programmed PIC, transistors, caps, diodes - everything but the enclosure and the mints.

First time builders please note: This kit is an ideal first kit to build. It is inexpensive, has a small number of parts and the pc board is uncomplicated. Complete instructions and EZ building assure success..
