  We report discovery of KFe$_{1.05}$Ag$_{0.88}$Te$_{2}$ single crystals with
semiconducting spin glass ground state. Composition and structure analysis
suggest nearly stoichiometric I4/mmm space group but allow for the existence of
vacancies, absent in long range semiconducting antiferromagnet
KFe$_{0.85}$Ag$_{1.15}$Te$_{2}$. The subtle change in stoichometry in Fe/Ag
sublattice changes magnetic ground state but not conductivity, giving further
insight into the semiconducting gap mechanism.
