[QUOTE="aceb, post: 1064267, member: 268811"] The dongle is tuned to the transponder frequency minus the IF frequency so you only need to add 9,750,000 via the shift window if you want to see the frequency the LNB is receiving. The actual frequency of the dongle doesn't change from whatever it is set to with a zero shift so a typical RTL with sufficient cooling will allow reception of sat signals upto 11.5GHz, I guess if you inserted 22kHz into the feed you could shift the LNB to the higher band. The E4000 tuner allows higher reception [URL="https://www.ebay.co.uk/itm/162674463072"]NooElec NESDR XTR+ RTL-SDR USB Receiver Set w/ TCXO, RTL2832U & E4000 2.3GHz UK 616469145819 | eBay[/URL] [/QUOTE]
