I notice in the SmartSDR version 2.4.9 there is a new CAT Port Protocol of NIMMSPOT. How is this used with N1MM spotting. It appears it has default UDP port of 12601 and a Lifetime (S) parameter which I assume relates to time with a default of 3600 and I assume this is seconds. There is no mention of this protocol type in the SmartSDR documentation for CAT as there is no 2.49 Cat document that I'm able to locate. What's this new protocol all about and how do I use it with N1MM?
