[[Image:Sea-Pol radar base.jpeg|center|thumb|300px|Sea-Pol radar base foundation]]
Modifications to the ASR11 transmitter were made to allow the RF output power to be delivered in two separate waveguides to supply the H and V polarization antenna ports. Temporary shelving suspended from the ceiling of the CSU-CHILL shop was used to support the dummy loads, etc. that were used during the initial split output configuration tests.

In preparation for thunderstorm season operations, the CSU-CHILL radar was returned to dual frequency (S and X-Bands) on 28 May 2013.
Two 20 foot containers that will house the Sea Pol radar equipment have been delivered to the CSU-CHILL radar site.

This is an NSF-funded project using the [[Facilities#FRONT|FRONT]] facility. Principal Investigator: Dr. Sandra Yuter.
The initial installation of the X-band only feed horn took place on 17 December 2012 following the removal of the dual-wavelength feed. Test data was collected during a widespread snow event on 18 - 19 December.
