We have a bunch ~10 degrees or so. Full duplex. It helps if you can mount the non-co located ends so they can only see their other end and not the second co located radio. Similar distance links work better as the issue is the slave ends seeing both radios. Try turning the power down.
At 400', I'd try turning rx gain off on the slave end and lowering its power. > On May 13, 2015, at 9:20 PM, Jeremy <jeremysmi...@gmail.com> wrote: > > There are users on this list running them 8 degrees apart without any issues. > >> On Wed, May 13, 2015 at 7:18 PM, George Skorup (Cyber Broadcasting) >> <geo...@cbcast.com> wrote: >> I believe Chuck said GPS does nothing in FDD mode.
