Thanks for the reply,

I figured that the first time through, there would be no value, but after any use of the device, from there to eternity, there would be a value to work with. Subsequent tries are still not working as expected.

In light of your advice, I will look at it again and see where I can get something out to determine what I'm missing.

Darrel, If you looked at the whole thing, you may have noticed that there was a block in there that you suggested for the RX. I haven' completely understood it yet so I haven't implemented it yet. I like what I understand and I will get to it, so please don't feel your efforts were in vain.

Thanks again
Bo
