The advantages and disadvantages of “two-storey” constructions and design with vertical positioning of power amplifier boards with respect to the TCP are shown. The paper proposes the RSSPA, in which its components with a high heat dissipation and the components directly connected with them are placed on the base of the RSSPA case mounted on the TCP via a thermally conductive pad, and all other components are placed on the side walls of the case. Its design is simpler and lighter.

To prove the concept an experimental test-bed consisting of four identical generators of 100–500 MHz band has been developed.

The approach used is related to the study of the change in the entropy of the measured fields, which occurs as a result of the activation of the processes of faults of lithospheric plates immediately before an earthquake. It was possible to reveal the phenomenon of processes with a high degree of determinism that occur before a seismic event. A change in the nature of the movement of stations of space geodesy and geodynamics of the CrAO for all coordinates was registered a few days before the start of the block of Turkish earthquakes, which indicates a change in the balance of forces in the region.","PeriodicalId":117144,"journal":{"name":"Infocommunications and Radio Technologies","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130120628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
