Abstract: Technical VLBI experiments have been carried out at wavelengths shorter than 3mm, yielding the highest angular resolutions ever attained in any waveband. Long baseline detections of AGN at 129GHz, 147GHz, and 230GHz have fringe spacings (λD) of 56, 49, and 34μas respectively. We also present the first 129GHz VLBI map of the SiO masers associated with the evolved star VY CMa.
