PJMonty, That is pretty much what I do.  The wire length between the sx-key and the target board is about 6 inches and I actually have the key enclosed in a box. The box has a Serial connector attached to the enclosure and takes all the abuse of the regular serial cable. A bit excessive? I say YES! The SX-KEY is great, but I noted when I first recieved it that the connection between the target board and the key recieves excessive physical stress. This is typically due to the key wanting to go one way and the target board the other, connectors like the one provided are not designed specifically for this and will show wear as a result. If your work space is tidy and have strapped everything down plus you don't connect and disconnect often you should have no problems. But I am notoriously messy and tend to be on occasion clumsy, known for example to trip on wires and bump my head.  I typically do leave the two connected about 50% of the time but the other 50% I am connecting and disconnecting. I have for example over the past week connected and disconnected around 20-30 or so times. This is alot I know.

I think that the use of the hardware that you suggested PJ along with a dedicated, anchored board/sx-key pair would ensure years of reliable use.

James, sometimes I program with the resonator in place due to laziness. Yesterday I was programming without the resonator connected.  I know not following protocol can cause issues and even damage (mostly to the resonator), but living life dangerously can often be exhilarating!
