30dec99 -- Pnting error ~ 5"
16dec99 -- pointing and focus tuned up. Data OK -- amps low
by factor of 2 due to panel surface.
14dec99 -- need to tune up pointing and focus for best efficiency.
02dec99 -- modified F3 module (with programmed prom for wider
and more stable frequency tuning) has been installed.
Rx is ready to go.
18nov99 -- K.Sowinski entered the rotation setting (-3886) in SYSQROT
and removed the flags for antenna 10 in SYSQIF.
Tcals set to something plausible.

26nov99 -- Subreflector rotation-correction determined by
K.Sowinski and input into the online system.
24nov99 -- Alignment problem fixed: pointing model
updated by K.Sowinski
22nov99 -- No fringes at K and Q band after alignment work
15nov99 -- Q band holography shows subreflector offset in Y =
1cm. This can be corrected for in rotation.

30nov99 -- To = 60 K
03dec99 -- This reciever now working properly.
02dec99 -- Durga suggests the LCP mixer-trippler may be
unstable intermittently, causing loss of coherence.
Bob replaced mixer-tripper. Initial tests at 42 GHz
show amplitudes are normal.
29nov99 -- Subreflector offset exists in Y direction. Amps
down by 20 - 30%. Will be corrected for in
rotation by Jan 1.
28nov99 -- more testing to isolate LCP amp problem
22nov99 -- LCP amps (ANTSOL vals) down again ==> intermittent pblm
16-20nov99 -- LCP amplitudes normal
10nov99 -- BE testing: LO chain swapped with ANT22
01nov99 -- Front end behaves well, good To ==> BE
22oct99 -- LCP amplitudes low: 1/4 normal value

removed for antenna 24 in SYSQIF and Tcals set by K. Sowinski.
