We have successfully commanded both of ISEE-3's data multiplexers into engineering telemetry mode. The current bitrate is 512 bits/sec. We have been able to verify modulated data through ground stations in Bochum Germany, Morehead State in Kentucky, and the SETI Allen Array in California. We will not be transmitting over the next few days but concentrating on studying telemetry we receive from the spacecraft. We are setting up, with the cooperation of Arecibo, a means to remotely command the spacecraft.
