PIC Keyer

K1EL has two pretty good PIC keyer designs available (K8, K9) but unfortunately he decided to pull the source code because he was being ripped off by unscrupulous idiots.

However, the K8 code can be had if one has sufficient google-fu. The K9 code not so much.

The only difference between the K8 and K9 is in the firmware (OK,the K9 has a few extra bypass capacitors). The K10 is a completely different animal which uses an A/D converter to read three buttons and a pot.
