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
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
