A week or so ago, someone asked about keyers.
There was a short review in the February QST about a K3 keyer from
Idiompress. It had a range from 5-60WPM and had many programmable options
including weighting, character spacing, compensation if your transceiver
cuts off the first character, 6 255-character memories which can be
subdivided into smaller ones, and a contesting mode with serial number
generation.
