Thanks Languer, I have tried everything wired before I went to RF, but, I did not make any changes to the qualifier. I was bored last Friday so reading over my code i realized that obviously the qualifier is not Manchester Encoded so I was thinking if I am sending a preamble of %10101010 preceding the qualifier 254,%11111110,what happens to the data slicer so curiosity got the better of me. I then thought that I could keep the data slicer balance by sending 170, %10101010. Thats when I found that I had a problem. when I changed it to 170 or whatever it became intermittent. By keeping it 254 I could operate this way over a couple of hundred feet with only a rare hiccup, stutter or whatever its called, but that is only when I was going close around my metal shop and vehicle. I've been trying to figure out some of the examples I have found on the CRC though. Instead of cut, copy and pasting them to my code I am trying to understand how each line works before I tailor it to my need.
Again, many thanks
