frequency
00H- 33H，for 425 – 450.5MHz
When the frequency-hopping quantity
sets as 1, the module works only at the
fixed frequency (425M + CHAN *
0.5M). Otherwise the module works at
a
(425MHz+CHAN*0.5MHz+FHSS_nu
ms*0.5MHz).
-----------------------------------------------
This bit is used to the module internal
pull-up resistor. It also increases the
level's adaptability in case of open
drain. But in some cases, it may need
external pull-up resistor.

0 is recommended.

After turn off FEC, the actual data
transmission
anti-interference
Also, the transmission distance is
relatively short.
Both communication parties must keep
on the same pages about turn-on or
turn-off FEC.
-----------------------------------------------
The external power must make sure the
ability of current output more than
300mA and ensure the power supply
ripple within 100mV.
Low
power
recommended due to its low power
supply efficiency.
