I've just started DSS35 for v252bb recording 16MHz x 2IF x 2pol while PA/AT/MP recording 4IF x 2 pol. I will have to switch to DSS-34 in 5 hour time but this antenna can only do single pol. So I am thinking to record 16MHz x 4IFx 1 pol, say, RCP with DSS-34, applying the DAS Skyfreq. 8425GHz and 8457 MHz. This will cover the same total bandwidth as the former part. You might have to modify the vex file to correlate the extra-band though, hope you can work it out to get fringes.
