Works flawless  Time owned: 0 to 3 months
As my portable TRX does not have an electronic keyer on board, I needed to make one myself (commercial items cost too much for what it is). Now, I am not comfortable with programming microcontrollers, but Steve K1EL obviously is!

I simply ordered a K9 (has all the features I needed), emailed Steve the data (callsing, preferences a.s.o.) to program the chip, and "voilą": some days later I received my K9. I ordered the PCB too (2US$ extra), but for practical reasons, I hardwired mine on a strip of perfboard. This way, I could make the PCB fit exactly in the plastic box I bought.

You can download the manual from K1EL's site, it's complete and easy to understand, and it shows the schematic diagram to wire some extra components to the K9-chip. Few extra components are needed: 4 small capacitors, 1 resistor, 1 transistor and 1 push button.
I completed mine in no-time and... it worked FB from the first try! I am very happy with this keyer!

To sum it up:
* very cheap and fast delivery
* works great and no programming needed but still possible
* yet dozens of features on board (also beacon mode)

Satisfaction guaranteed *hi*
