TWP/CSAPR/I10 - PHIDP Incorrect
DataStreams:twpcsaprsurI10.00, twpcsaprvertI10.00, twpcsaprsecI10.00, twpcsaprrhiI10.00
Description:
The CSAPR software was found to have a bug in controlling its Automatic Frequency Conrol 
(AFC) causing errors in PHIDP (specific differential phase).  This is often exhibited by 
the appearance of concentric rings in PHIDP where there are radar returns.
Suggestions: 
Do not use PHIDP, there is no recovery of this data due to the software bug.
