I was able to obtain an IC-7851 on loan for a day last week, and managed to perform the main receiver tests. Here is the link to my test report. http://www.ab4oj.com/icom/ic7850/7851rx_notes.pdf I hope to have an IC-7851 on loan for a longer period in the next month or two. This will enable me to conduct a complete test suite. 73, Adam VA7OJ/AB4OJ
