  Starting in 1991 we have performed a regular monitoring of EGRET sources with
the Effelsberg 100-m telescope and the IRAM 30-m at Pico Veleta. In comparison
with data on a sample of flat-spectrum quasars which have not been seen by
EGRET we search for correlations of any kind in the behaviour of FSRQ's in the
radio and gamma-ray regime. While there is no radio-to-gamma-ray luminosity
correlation for these sources, it seems that gamma-ray high states coincide
with increased activity in the radio regime with a strong tendency that
gamma-ray outbursts precede radio outbursts. The gamma-ray spectra seem to
harden with increasing flux level.
