[evlatests] 4-band status

[Rob Long]

Antennas 1, 5, 25 (and probably others) have not had the B & D T304 
attenuator levels set as of 11:40 this morning.  I just set 1, 5, & 25 
up at 4-band and found attenuator levels set at -1 (meaning no values in 
the LUT yet).  The bandpass' look good and backend data looks good with 
levels properly set.

As we get more antennas up and running at 74 MHz, we will have to keep 
an eye out for incorrectly set levels.
