We had several requests for normal V/U repeater mode for various operating demonstrations and grid expeditions, but we also managed to fit in a few other modes in between the requested V/U dates. We do have one special request. During the SSB/FM cross-mode repeater July 24-26, please restrict your uplink power to reasonable levels. Last time there were some issues with very strong stations causing distortion on the downlink.
73 and enjoy, Drew KO4MA AMSAT-NA VP of Operations
