LRLL 54361 is an infrared source located in the star forming region IC 348SW. Remarkably, its infrared luminosity increases by a factor of 10 duringroughly one week every 25.34 days. To understand the origin of these remarkableperiodic variations, we obtained sensitive 3.3 cm JVLA radio continuumobservations of LRLL 54361 and its surroundings in six different epochs: threeof them during the IR-on state and three during the IR-off state. The radiosource associated with LRLL 54361 remained steady and did not show acorrelation with the IR variations. We suggest that the IR is tracing theresults of fast (with a timescale of days) pulsed accretion from an unseenbinary companion, while the radio traces an ionized outflow with an extent of$\sim$100 AU that smooths out the variability over a period of order a year.The average flux density measured in these 2014 observations, 27$\pm$5 $\mu$Jy,is about a factor of two less than that measured about 1.5 years before,$53\pm$11 $\mu$Jy, suggesting that variability in the radio is present, butover larger timescales than in the IR. We discuss other sources in the field,in particular two infrared/X-ray stars that show rapidly varyinggyrosynchrotron emission.
