have gnuradio companion 3.7.13.5 (UHD_3.14.1.HEAD-0-g5491b80e)
loaded UHD_3.14.1.0-0-g0d934195 firmware on the e320
downloaded and installed the FPGA for network mode on the e320
created a simple grc flow. 2 signal source (cosine) each going to a channel on the UHD: USRP Sink (Mb0 Subdev A:0 and A:1)
when it runs both transmit lights come on, but i only see one freq transmitted on my speca. i can get either freq to transmit out of either port, but never at the same time.
is this a limitation of grc or the e320?
i had tried a similar setup with a e310 in embedded mode with the same results.
