The Expanded Owens Valley Solar Array (EOVSA) is a solar-dedicated radio imaging array operating in the 1-18 GHz microwave range.  It performs microwave imaging spectroscopy of solar flares, active regions, and the quiet Sun to provide unique diagnostics.  These include dynamic magnetic field maps of flares, coronal magnetic field maps of active regions, high-energy particle acceleration and transport in flares and jets, and thermal plasma diagnostics in the lower solar corona.  A new, co-located radio instrument now being commissioned for solar-dedicated operation is the OVRO-Long-Wavelength-Array (OVRO-LWA), in the much lower frequency range of 20-88 MHz.  This all-sky imager has a solar-dedicated beam to provide extremely sensitive spectropolarimeter data at as low as 1 ms time resolution over 3072 frequency channels (25 kHz frequency resolution), a solar-dedicated “fast” imaging mode providing imaging capability at 0.1 s time resolution and 100 kHz frequency resolution for bursts (e.g. type II, III, and IV bursts), and a “slow” imaging mode for imaging the thermal emission from the quiet Sun and weak nonthermal emission from CMEs.  This poster describes the highlights of those instruments and invites the SHINE community to learn more about using radio data in your analyses of solar and heliospheric activity.
