Small bug fix and new configuration file ready to receive GPS signals in real-time with USRP devices and appropiate front-ends. Remember to tune the front-end gain (source section in config file) and, in some particular antenna and LNA setups, tune also the acquisition threshold (acquisition section). The configuration is tested on USRP v1 + DBSRX, USRP 2 + DBSRX and USRP B100 + WBX.
