I run an IRLP/Echolink simplex node using a Micro-Node Nano-Node. I am the only user, and I only connect to Echolink manually, and disconnect when I am done. I have all of the port forwarding setup. Everything works well--with one exception. There is one particular Echolink connected repeater which has a net every evening. The Echolink station at the repeater is seeing disconnects and reconnect every few seconds. The Nano-Node is reporting no such thing. This also does not appear to happen with any other Echolink or IRLP connection. Is there a problem on my end that I just cannot see, or is it at the repeater end?
