TVRX IF frequency is fixed at 44MHz, But the RFX400 IF frequency is 3MHz
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
