I have the RSPdx and have used it in numerous ways. At the moment it is part of my combined station and get a fair amount of use for monitoring band activity. I use a discone as well... as a dedicated V/UHF antenna on one input and through an SDR switch on HF. Very versatile with SDRuno.\r\n\r\nJack - KD4IZ\r\nSent from my iPhone\r\n\r\nOn Jan 26, 2021, at 18:14, Alan Rich <[email protected]> wrote:\r\n\r\n\r\nHi, I have an RSP2 that I connect up to an Arrow Yagi for 2m -70 cm amateur reception and a homebrew LHCP L band helix for LEO/MEO SAR downlink reception ( Via a couple of switches and LNAs). I like it and SDRUno a lot. PST Rotator and Com0CoM can be used for doppler compensation ( K3RRR has a nice YouTube video on this). I'm sure there are other good approaches too.\r\nAlan\r\nVE2NHR\r\n\r\n\r\nOn Tue, Jan 26, 2021 at 2:30 PM Gerald Payton <[email protected]<mailto:[email protected]>> wrote:\r\nIf I may ask if any members are using SDRPlay as monitoring for downlink signals?
