No but a buddy that has the 320 also and is connected to the collars to

Is your buddy able to track the collars further than you are?  If so that directly points to your Astro as the problem.  They have a wire that runs from the antenna connection into the guts of the Astro that has known to break.  If updates don't fix the problem it is time to contact Garmin. 1-800-1020
