Though the signal was not stationary, we kept track of this signal, and it continued to be present throughout the remainder of the dss-43 pass and the beginning of the dss-55 pass. During the measurements observed, this signal did not enter into the 2 KHz RSR recording bandwidth that is normally used by MGS during ingress or egress. The attached screen shots were taken during the last ingress (27782i) at dss-43 and the first egress (27783e) at dss-55. dss43-020554 shows a two-way signal with a frequency offset of +45000, placing the 2-way signal to the left of the FFT and the secondary signal to the right. The secondary signal was present prior to ena bling two-way non-coherent mode and entering ingress. dss43-020750 shows a secondary signal to the far left of the one-way signal during ingress. In dss55-025621, the secondary signal appears to the right of the one-way signal during egress. This signal behaved independently of whether the transmission was one-way or two-way, or whether MGS was supposed to be transmitting or not. Further investigation today revealed that this signal could still be found, even when the spacecraft was behind the planet. Further analysis will be forthcoming. *RS naming convention ** Radio Science open-loop Receiver (RSR) recording times. All times are in ERT. Best Regards, Daniel Kahan
