目前,台站使用传真机接收的天气图图面不够清晰,尤其是在复杂天气条件下,接收的天气图质量更难以满足工作需要,为改进接收质量,我们在传真机接收频率作了一些工作。具体作法是:首先从各发射台频率表上查到所使用频率,根据需要,与江西景德镇七一三厂联系。计划定购定频机频率插件。经试验,我们选购了上海台的5,100MH_2、7,420MH_2,18,940MH_2和日本台的7,305MH_2,四个频率插件,经使用新的插件后,收图效果有了很大的改善,收图质量有了明显提高。只有日本
At present, the weather map image received by the station using the fax machine is not clear enough, especially under complex weather conditions, the quality of the weather map received is more difficult to meet the needs of the work. In order to improve the receiving quality, we did some work on the receiving frequency of the fax machine . The specific approach is: First of all from the launch pad frequency table found on the frequency used, according to the need, and Jiangxi Jingdezhen seven one three factory contact. Plan to order frequency machine frequency plug-ins. After testing, we have purchased 5,100MH_2, 7,420MH_2, 18,940MH_2 of Shanghai station and 7,305MH_2 of Japan station, four frequency plug-in units. After using the new plug-in unit, the drawing effect has been greatly improved. Has been significantly improved. Only Japan
