…but is the data returned by ‘sbits’ exactly the same as the data returned by ‘sn’ except that ‘sbits’ is packed 8 stations to a byte? My interpretation of the doc is that they are but I was looking to validate that. Having 2 fields encoded differently in 2 different messages makes me think there is something different about them, unless ‘sbits’ was added cut down on the number of message polls one would have to do. If they are the same it would be good if the doc said so.
