回帖:validation - choose callsign
the callsign you entered is: bg6qlin
echolink can be set up with any of several different callsign suffixes. the callsign bg6qlin (with no suffix) is used in single-user mode, and the callsigns bg6qlin-l or bg6qlin-r are used in sysop mode. (sysop mode requires connecting a radio to your computer's sound card using a special interface device.) each of these three is considered a separate callsign, and must be validated separately for echolink.
这是什么意思,麻烦dx帮忙翻译一下.
