I thought something looked funny. I will notify John Klose. The strongest are about 20 dB below the carrier, so you should have no trouble spotting them in real time. This is what we said in HEA5306A.TXT about the previous event. I did not check whether the SNR was affected this time. - - - - - - - - - - - - - - The DSS 45 spur problem (see HEA5300A.TXT) makes the data through 2005/303 of questionable science value. Not only are there large spurs every 120 Hz in the frequency domain, but the SNR is 25 dB lower than would be expected. Kevin Piechowski at the Canberra complex reported a solution on 2005/304: Today we replaced a failed 15V power supply in the S/X downconverter on DSS45. This impacted the bandpass on both S-Band and X-Band downlink signals. I'm surmising that this may have caused the problem on MGS.
