Monitor audio in the 6700 vs 5000

In the Flex 5000 with 2nd rx it looked like a -80dbc pad from the rf driver to the PA being relay switched to the RX1 input if monitor was selected in TX mode. This seems to indicate that I actually monitored "demod'" audio as would be transmitted within the RX/TX filter boundaries. Is there a similar path with the 6xxx series or is the monitor just a simple pick off from a codec output of post eq/comp and not an actual "demod" from a receiver? Not worried about latency.

The simple answer is that we have both in the 6000 series hardware -- we have both the return path within the codec that lets you listen to your input audio + processing with minimal latency (this is enabled with the MON button) AND a hardware path that allows us to connect the transmitter to a receiver via a pad (not currently used in SmartSDR for Windows). Note that we use the latter in production test to verify the radio performance.
