[srslte-users] pdsch_ue and cell_search can't find any networks.

[Nazir Ikhtiari]

PS: I was getting the following warnings when running pdsch_ue:

UHD warning:
    The hardware does not support the requested RX sample rate:
    Target sampling rate: 1.920000 MSps
    Actual sampling rate: 1.923077 MSps.

UHD warning:
    The hardware does not support the requested TX sample rate:
    Target sampling rate: 1.920000 MSps
    Actual sampling rate: 1.923077 MSps

I assume the 2nd warning shouldn't be an issue since, pdshc_ue will only be
receiving.
