hmm there is a 2nd channel, I got one on 3.58mhz and the ID is 4.
The modem d/c by itself and recconected and I was on that channel but it couldnt lock to a downstream so I waited and then it came back online but back on 4.58mhz
I have had about 2 or 3 d/c during the day as well which were not me messing about.
