Icom IC-7760 support The IC-7760 transceiver is now a supported receiver. Connect the RF deck's rear USB port and SDR-Receiver streams its I/Q output at 1.92 MHz, with RF gain, attenuator, preamp, IP Plus and antenna selection. Both the Main and Sub receivers can be used — choose which one feeds the panadapter, and each remembers its own tuning. FM de-emphasis A new DE control beside the audio filters selects the FM de-emphasis time constant — Off, 50, 75, 530 or 750 µs — with WFM and NFM each remembering their own. Use 50 µs for broadcast FM outside the Americas and 75 µs inside. Smoother bandwidth control Dragging the bandwidth slider no longer produces crackling in the audio. Wider bandwidth range Narrow FM now reaches down to 2.5 kHz and wide FM down to 50 kHz, for pulling a signal out of a crowded band. Easier gain adjustment Receivers with many discrete gain or attenuator steps now use a slider that snaps to the steps the hardware actually has, instead of a long scrolling list. AIS on both channels AIS can now receive channels A and B at the same time. Vessels alternate between the two, so watching both roughly doubles the traffic you see. RTL-SDR direct sampling RTL-SDR sticks with the hardware modification — and the Blog V3, which has it built in — can bypass the tuner and receive 0–14.4 MHz directly.

This update (1.09) is a bug-fix release for owners of RTL-SDR hardware specifically: it corrects the tunable frequency range reported for different RTL-SDR tuner chips (previously one fixed range was shown for every stick), and fixes a gain-control popover that could render wider than the window on tuners with many discrete gain steps.
