As previously stated, SDR dongles trade sensitivity for bandwidth. They are as deaf as a post and unsuitable for repeater use. If you do the math for the noise floor at wider bandwidths, you will see that a lot of sensitivity is lost, whereas a narrow band conventional receiver is much more suitable.

Martin - Good point about SD Receivers for use on repeaters. Given that equipment for a repeater is "big investment... but usually one 1x", it may well make more sense to use discrete (sensitive) receivers on a repeater system.
