【無線】LCRは音が悪いのか？比較実験 LCRの音質改善方法 デジタル小電力コミュニティ無線 IC-DRC1 DJ-PV1D

LCR is a digital low-power community radio that is generally considered to have poor sound quality. I experimented to see if I could improve the demodulated sound. Characters Marushii / Broadcaster Callsign is Azumino CT271. Started with special small radio, then expanded to license-free radio LCR and DCR. Currently, I mainly operate LCR as a fixed radio and a mobile radio in the mountains. Callsigns can be written in either hiragana or katakana.

License-free radio? According to Article 4 of the Radio Law, permission from the Minister of Internal Affairs and Communications is required to open a radio station. In other words, a license is required to play with radio. However, Article 4 stipulates exceptions, and among them are so-called license-free radio. There are digital simple radio (351MHz/5W), digital low-power community radio (144MHz/0.5W), specific low-power radio (430MHz/10mW), and citizen radio (27MHz/0.5W). With the exception of digital simple radio (DCR), anyone can purchase and use it on the spot. DCR can be used without a radio operator license by registering with the General Communications Bureau and receiving a registration letter. #digital simple radio #radio #license-free radio
