If your 320 is showing the bark indicator i would believe it is updated.
You didnt ask me but my alpha usually picks up 1.5 pretty easy and i have seen it just over two miles a few times. Terrain plays the biggest part in range. My 320 and dc30's would do the same range from time to time it just seems the alpha does it more consistently.
So sorry I left you out!!!

but thanks for the reply anyways...
Do the alphas pick up the extra satellites too??
I'd be good with 2 miles... The only reason I let them get over a mile on the hunt was because once they struck I laid back and dozed off...

Not sure how far they were when I wasn't picking them up but I had to be within a mile to get communication...
