Working on a dual S/X feed supporting simultaneous RHCP/LHCP RX . There are 2x S band BPFs, 2x LNAs connected to Lime's Ch1/Ch2. A simple GRC flowgraph streams over UDP to 2 SatDump instances.
The coupler/120 deg phase shifter has been based on Maarten Baert's inspiring work.

Very first attempt to simultaneously receive L-band (1698 MHz) and S-band (2247.5 MHz) NOAA-19 downlinks using the experimental L/S/X feed.

Working on a L/S/X triband feed for WX/EO satellites. Have been using a partially 3D printed L/X feed so far, but it was time for an upgrade. Pictures show the ugly prototype in the focus of my 1.4 m dish on the balcony. It looks promising but more testing is needed of course.
