Key issues of the MWRH project: the number of antenna elements and the configuration of using them at the new frequencies, frequency-agile feeders, versions of collection of signals from antennas, heterodynes of frequency conversion 1 and 2, fiber-optic lines to supply the heterodyne signal to antennas, separation and digitizing data at all frequencies, data preprocessing and storage, SolarSoft, system analysis, and matching of all subsystems. Cooperation, exchange of experience or sharing of labor with relevant teams of the FASR project are possible and expedient in the process of working out these issues.
     State of affairs. There is well-established cooperation of manufacturers of the necessary additional equipment. Control systems and systems for controlling over antennas, phase shifters and synthesizers are under development using the state-of-the-art designs. New acoustooptic receivers are being produced, which permit, already in the year 2002, recording two-dimensional images every 2-3 minutes simultaneously with one-dimensional scans from both beams, with a resolution of 14 ms. Receivers, amplifiers and synthesizers for 6 frequencies are under development. The technology for building multiwave feeders is being worked out. Thus, with relatively low expenses (of about 15 million rubles), in a period of two-three years it is possible to obtain a qualitatively new instrument which outperforms the existing solar radio telescopes for the set of their characteristics: the two-dimensional mode of operation with high spatial resolution at six wavelengths, the possibility of observations throughout the daytime, the possibility of carrying out patrol of fast processes on the full disk with high temporal and angular resolution.
