We present the first results from the Fundamental Reference AGN MonitoringExperiment (FRAMEx), an observational campaign dedicated to understanding thephysical processes that affect the apparent positions and morphologies of AGNs.In this work, we obtained simultaneous Swift X-ray Telescope (XRT) and VeryLong Baseline Array (VLBA) radio observations for a snapshot campaign of 25local AGNs that form a volume-complete sample with hard X-ray (14-195 keV)luminosities above $10^{42}$erg s$^{-1}$, out to a distance of 40 Mpc. Despiteachieving an observation depth of $\sim20$ $\mu$Jy, we find that 16 of 25 AGNsin our sample are not detected with the VLBA on milli-arcsecond (sub-parsec)scales, and the corresponding core radio luminosity upper limits aresystematically below predictions from the Fundamental Plane of black holeactivity. Using archival Jansky Very Large Array (VLA) radio measurements, oursample jumps back onto the Fundamental Plane, suggesting that extended radioemission is responsible for the apparent correlation between radio emission,X-ray emission, and black hole mass. We suggest that this discrepancy is likelydue to extra-nuclear radio emission produced via interactions between the AGNand host environment. We compare VLBA observations of AGNs to VLA observationsof nearby Galactic black holes (GBHs) and we find a mass-independentcorrelation between radio and X-ray luminosities of black holes of$L_\mathrm{6cm}$/$L_\mathrm{2-10 keV}$ $\sim$ 10$^{-6}$, in line withpredictions for coronal emission, but allowing for the possibility of trulyradio silent AGNs.
