Any recommendations for a low cost Iambic cw key?
Do you really mean an iambic keyer, or do you mean a high speed
electronic keyer. In my view, using iambic keyers is now becoming a
skill that one only learns for the challenge of learning it. If you
want a skill that could be useful in an emergency, using a straight key
is better, as it is much easier to improvise a directly keyed
transmitter. If you want fast and cheap sending, using a PC keyboard or
PDA folding keyboard and a microcontroller provides a much cheaper
solution, as it is basically using commodity parts, whereas iambic
keyers are low volume products for a premium market.
When they were first developed, the only cost effective implementation
method was discrete or SSI electronics, but now microcontrollers capable
of working directly from a keyboard are only a few dollards and
keyboards are also very cheap.
