[evlatests] Noisy C-band antennas?

Some months ago, Pedro noted that certain antennas were especially noisy
(low SNR) for some antennas and spectral windows, when using 3-bit
samplers. From my own data, I confirmed this.
The recent data referred to in my last circular allows a check on this
situation -- the data were taken with 3-bit sampler.
The 'noisy' effect is completely gone! All antennas, in all spectral
windows, have exactly the expected sensitivity and gains.
Pedro plans to take some data, to confirm.
