Drew Diamond (VK3XU) is well known for his home brew projects. I was prompted by his article "Mark 4 CW transmitter for 3.5MHz and 7MHz" in August 2006 AR, to send Drew a couple of PIK chips.
Drew applied his creative mind to the task, evaluated the PIK keyer, and designed and constructed a PIK based keyer. The following tells the story in pictures...
Drew is an accomplished CW operator with an excellent "fist". His opinion of the PIK... "the keyer performs faultlessly on-air", but that speaks more of the human interface aspects of WB4VVF's Accu-Keyer design than of the PIK, which could be viewed as a microcontroller based emulation of that human interface.
