Notch Filter and antenna ports for RSP2
Posted: Wed Jan 11, 2017 4:09 pm
The spec says the AM broadcast MW Notch Filter >30dB is designed for 680-1550 kHz. According to the block diagram the Notch Filter is only valid for antenna port A and B. However port A and B are specified for 1500 kHz - 2 GHz. The Hi Z port which does not have the Notch Filter is specified for 1 kHz - 30MHz. I do not understand this. Please explain. At a U-tube presentation of the RSP2 there is said that the performance is decreased below
1500 kHz for port A and B so it will not meet spec. What specific performance is decreased below 1500 kHz for these ports?
What do I gain and what do I miss when I use the Hi Z port?
I am interested to buy a RSP2 and my main interest is AM broadcasts in the MW and SW bands.
