We present results from monitoring three δ Scuti variables. GW UMa is found to be a stable, monoperiodic, high-amplitude δ Scuti variable with a revised period of 0.20319389 days. We also report a full radial velocity curve, a near-solar metal content, and a rotational velocity of 15±5 km/s. From a very short time line we find that BO Lyn has a constant period change of -1.5x10^–10 days/day. We also find two potential secondary frequencies of f₂=15.81 and f₃=13.60 cycles/day. Finally, we report some unusual results for AN Lyn. We show that the period and amplitude are changing in phase and that this change is related to a binary companion.
