Thanks for the reshuffle and reminding me on the band info, actually some people can use 443 in the US, it is a ham band as a secondary allocation. I just want to make sure I was setting legal bands by default. At this power level it will be hard to be noticed, but it is wise to stay legal.
I will set things up tomorrow for a test without interrupts defined.
@Icing, is the antenna cut for a particular frequency?
