[QUOTE="s-band, post: 1059614, member: 407744"] It depends what you want from it. PLL with ext ref is important for saddos like me who look for beacons and other narrow band signals. The last dB of s/n on DVB doesn't matter to me most of the time. It would be very tempting to mod an 8000RI by adding a PLL LO as it is very good value.
