-BNC's function is limited today to processing C1, C2, P1, P2, L1, L2, SNR1, and SNR2 observations. Which observables become available through a specific stream depends on the setup of the affected receiver and the applied data format. Note that RTCM Version 2.x streams can not transport signal-to-noise ratios (SNR) and RTCM Version 3 streams can only transport one code observable per frequency. Note further that signal-to-noise ratios SNR1 and SNR2 are mapped to integer numbers 1 to 9.

-If the ambiguity field is not set in RTCM Version 3 streams (i.e. when sending message type 1003 but no 1004), the BNC output will be no valid RINEX. All values will be stored modulo 299792.458. (It would be necessary to approximately calculate the range to fix the ambiguity, needing ephemeris/almanac and an easy positioning algorithm).
