  Strangeness photoproduction in the elementary reactions $\gamma N\rightarrow
KY$ offers the possibility to study nucleon resonances in the mass region above
1.7 GeV, where the number of states and their properties are still under
debate. These reactions could allow the first 'complete' experiment in
pseudoscalar meson photoproduction due to the easier access to recoil
polarization observables in experiments. In addition to measurements on proton
targets, a full isospin decomposition of the $I=1/2$ electromagnetic amplitudes
requires also data obtained from quasifree neutron targets. This contribution
shows first preliminary results on feasibility studies for such measurements at
the A2 experiment at MAMI.
