This is most likely a leftover while we developing the code, that the gain for band-averaged broadband calibration (for pulse compressed outputs) for EK80 now actually hard codes the gain to be 27, instead of pulling it from the data file. There is also a TODO for generating the gain at the center frequency in the actual transmit signal band.

Let's get this fixed very soon.
