! w1_vddc_50cm.set ! ! 512 Mbps VLBA only recording using 2 polz, 4 freq channels, ! 2 MHz bandwidth with 50cm receiver. Uses DDC personality ! of 2 RDBEs to get all 8 subbands. The 4 subband (pairs) ! are adjacent in frequency. No rx filter. Some stations ! have RFI that saturates the rx. ! ! For this setup, have ! 576.0 - 592.0 MHz ! 592.0 - 608.0 MHz ! 608.0 - 624.0 MHz ! 624.0 - 640.0 MHz ! ! Note that freq.dat says max range for 50cm rx with no rxi ! filter is 588 - 633 MHz. Would have been best to center ! the subbands in the center of this range (610.5 MHz), but ! that leads to the highest frequency subband 626.5 - 642.5 ! MHz, which crosses the 640 MHz crossover boundary in the ! DDC. (No first L.O.) ! !
