Ok, I'm a new in-list-ment: and:

I find the system cryptic... I'm running linux Mint 18.3 and firefox as a browser.. I can get the list pages for each of the nodes, BUT...

HOW do I access the transmit/receive mode for them???  EchoLink has the connect function and a trans/rec togle , I see none on the list pages... Is there some software I need to download or just What special key do I push?  WHAT AM I MISSING???
