Hello all,

Now the filter is working correctly. Thanks to Bean for persisting, and Chris for your earlier support !

I think we had 2 problems:

1. An bug in the program: serByte = RX_BYTE was added after reading the 3 header bytes. That pushed all the other values out of sync.

2. Maybe the SX-Key being plugged in whilst testing was interfering with the frequency, as I was using an external 50mhz resonator at the same time. This may have conflicted with the resonator on the SX-Key??? Not sure, but don't want to test it plugged in again now incase I damage it!

These were the only changes of substance that I made before trying the N57600 again. I guess they were enough.


Many thanks again for the help. I feel far more confident with how the SX works now and look forward to putting this and future devices into production.

Parallax and its community make the SX well worth the effort!

Max.
