What kind of label and which protocol do you use? What does the result
look like?
I'm using the protocol of Engler-Blum et al. Anal.Biochem. 210, p.235 (1993)
with DIG-labeled DNA- or RNA-probes. This protocol works good for me.
I didn't compare it directly to radioactive Northerns but I was able to
detect rare mRNAs.
