[evlatests] Qaud 4 correlator problems update. (fwd)

[Michael Rupen]

Might be worth checking your data for this -- Ray is interested in knowing
which IF the high amp. horrors appear in, as he swapped some cards on 
Thursday.  Any data taken after then would be worth checking.

Cheers,

        Michael

Subject: Qaud 4 correlator problems update.

 	I have swapped a couple of cards in an attempt to fix/diagnose the 
intermittent problem causing high amplitudes on numerous baselines in Quad 4.

7/18/07
Replaced Int. Driver for Q4, DCS 10-16 (Sn 14 out. Sn 10 in.)
Swapped Mem. Cntrl. cards between Quad 4 and Quad 2 (Original locations, Q4=sn 
2, Q2=sn 4.)

 	Please keep me informed of any reports of periods of high amplitudes 
for numerous baselines involving antennas 5, 10, 14, 15, 20, 22, and 28 in 
particular. Please check data from Quads 2 and 4 (both LCP IFs). Pass this 
along to other parties involved. Thanks.
