Abstract
We begin an investigation into the spectrum of (non-uniform) Kirkman frames of type h u m 1, paying particular attention to the cases where h ∈{2,4,6,8,10,12}. We show that for each of these values of h the obvious necessary conditions on u, m are sufficient in all but at most 24 cases of (h,u,m).
