I finally got around to boxing up the 10w CW module i bought off ebay. I mated it up with a SI5351A and Arduino, a home brew keyer and put it on the air tonight to give it a test. I was Txing only as I am yet to make a matching receiver to go with this, but that will be the next task.
Rear panel and the internals.
