- FT6119
- Gs and Wf have been recording all four bands using UDCs, RDBE-Gs and Mark6.
- Ws and Yj recorded band B (sky frequency of 4712.4 GHz) with the DBBC2 and Mark6.
- The PCFS (version 9.12.13 ) was used to control the systems.
- Fringes were detected for both polarization for Ws but only 1 for Yj (configuration error was the cause for not both polarization's).
- FT6128 was a retest of FT6119 with the goal of correcting configuration issues and other anomalies observed.
- Fringes were detected for both polarization for Ws and Yj.
- Anomalies still existed.
- FT6140 incorporated BandC ( 5832.4 GHz)into the observation for Ws and Yj (2 Band Test)FT6XXX Next steps under discussion.
- Fringes were detected for both bands / pols.
- Improved performance to earlier tests
- Investigations continues.
- Yj, RDBE-G was tagged along on Band B. No fringes detected, problem determined.

Westford Mixed Mode Fringe Testing
On July 19th Westford tagged along in a mixed mode test (broadband and legacy observing) with RD1606. Westford observed the entire RD session, but the Haystack correlator will process 1 hour of data. Once the correlation procedures are verified and updated they will be sent to Bonn with the goal of expanding the knowledge of mixed mode processing, before USNO, and inclusion of broadband systems with existing legacy observations.

Technology Updates
DBBC3
The development activity is mainly concentrated on the realization of the unified control software which connects all the functionalities realised by the different parts of the system.
