I just wanted to receive time-synchronized channels.

Hello YENDstudio,

Do you actually need a two-channel receiver? Maybe you can get away by using two separate SDRs (possibly synchronized with PPS and 10MHz clock) and a splitter (or two antennas). 

An another alternative would be adding a custom mixer (and a filter, if needed) between the SDR and the antenna.

제목: [Discuss-gnuradio] Two channel receiver

Does anyone know any affordable (not thousands) SDR which can receive two frequencies separately. I want to receive LTE UL and DL channels which can be more than 100 MHz appart. The LO offset in USRP B210 and Limesdr is not enough to cover the two frequencies with a shared frequency synthesizer.
