I'm still having problems in random area's where the "T" symbol disappears and i am unable to receive transmissions. My question is i have tried setting multi-site on all three options and still have the problem from time to time. If i was to set it to "roam" do i need to change the Threshold Hi and low since its a rebanded system? Or do i need to change anything b/c its a rebanded system? And if there is nothing to change on the PSR-310 then which multi-site setting do u guys recommend?
