The DBBC3 was further enhanced by introducing\ua0new modes. Three different firmwares have\ua0recently been implemented for observing: Direct Sampling\ua0Conversion (DSC), arbitrary selection of bands\ua0(OCT), and Digital Down Conversion (DDC). These\ua0modes cover all the requirements of astronomical,\ua0VGOS, and legacy geodetic VLBI for the time being\ua0and the immediate future. In addition, the DBBC3\ua0offers unsurpassed compatibility to the relatively large\ua0number of other existing VLBI backends. A number\ua0of test observations were performed in the last months\ua0to achieve the best performance of the VGOS modes,\ua0and similar tests are planned for the EVN network. At\ua0the same time the DBBC3 is an important platform\ua0for additional new modes to be implemented for\ua0the BRAND receiver. Several DBBC3 systems are\ua0deployed in the field and more are under construction,\ua0with the number of 4-GHz bands ranging from two up\ua0to eight with resulting output data rates from 32 Gbps\ua0to 128 Gbps
