[Discuss-gnuradio] IF frequency of RFX400

[melanio]

Hi,

 

TVRX IF frequency is fixed at 44MHz, But the RFX400 IF frequency is 3MHz or 4MHz, so DDC is -3MHz or -4MHz.

What is the reason does not use the fixed IF frequency?

I think which is not fixed seems to be a bit complicated. I wonder why different IF frequency is necessary such as 3or 4MHz…

Is it the constraint because of the hardware?

 

can some help me with this problem?

thanks in advance
