  In this work we report the results of a nineteen-month Fast Radio Burst
observational campaign carried out with the North-South arm of the Medicina
Northern Cross radio telescope at 408~MHz in which we monitored four repeating
sources: FRB20180916B, FRB20181030A, FRB20200120E and FRB20201124A. We present
the current state of the instrument and the detection and characterisation of
three bursts from FRB20180916B. Given our observing time, our detections are
consistent with the event number we expect from the known burst rate ($2.7 \pm
1.9$ above our 10$\sigma$, 38~Jy~ms detection threshold) in the 5.2 day active
window of the source, further confirming the source periodicity. We detect no
bursts from the other sources. We turn this result into a 95\% confidence level
lower limit on the slope of the differential fluence distribution $\alpha$ to
be $\alpha > 2.1$ and $\alpha > 2.2$ for FRB20181030A and FRB20200120E
respectively. Given the known rate for FRB20201124A, we expect $1.0 \pm 1.1$
bursts from our campaign, consistent with our non-detection.
