The Turbo FEC code rate may be selected from the scroll list of preset rates dispayed on the screen.

Screen Description
"0.750 Industry de-facto 3/4 rate"
"0.493 Paradise 1/2 rate"
"0.875 Paradise 7/8 rate"
"0.789 Paradise 3/4 rate"
* Note on processing delay. Use the data rate before the FEC to determine the delay in milliseconds from
the delay in bits. For example at 1Mbps using Rate 0.789 Turbo FEC, the FEC delay is (6498/1000000)
seconds, which is 6.5ms.
