Does your NOPE know about turning off CONCSAN? On the other hand, if your receiver 's front end is being saturated rather than the PLL tracking the wrong frequency, then it appears to me that Voyager 1 and MGS should have swapped DSS-25 and DSS-15. Anyway you can check the detailed schedule (a crude overview is below) at Steve's web site: http://echo/asteroids/1999kw4_goldstone/html/1999kw4_planning.html#Goldstone and verify that we are talking same UT dates, but with a 30-40 sec. RTT, I can't check the state of the transmitter in detail without the logs that are still at DSS-14, and I am at JPL, trying to work on proposals. Given the burst times of the RFI, it seems consistent with transmitting at 1999 KW4, and the time span seems plausible. It actually seems like you should have seen more RFI... In overview, the schedule was: GOLDSTONE RADIATION REQUIREMENTS FOR MAY 2001 DOY DATE TXON TXOFF DSS TARGET PW BD DEC TRANSIT .... 143 MAY-23-01 1015 1355 14 AST. 1999KW4 520 X -21 1252 144 MAY-24-01 0855 1535 14 AST. 1999KW4 520 X -16 1157 145 MAY-25-01 0830 1445 14 AST. 1999KW4 520 X -08 1050 146 MAY-26-01 0520 1400 14 AST. 1999KW4 520 X +00 0938 148 MAY-28-01 0235 0655 14 AST. 1999KW4 520 X +16 N/A 148 MAY-28-01 0855 1215 14 MARS (INFRMY) 520 X -26 0912 149 MAY-29-01 0140 1030 14 AST. 1999KW4 520 X +20 0654 -- ALL DATES/TIMES ARE UT -- where TXON is the start time of the transmit window and TXOFF is the end time of transmit window, DEC is the average declination. It's unfortunate that the asteroid started out at such a southerly declination, since DSS-15 is south of DSS-14. Of course, we told the DSN not to put an antenna there (another km to the southeast and there would be a large hill blocking direct sight of DSS-14). I would guess that the geometry for this asteroid, and Ostro's desire to get high-resolution (I.e., wide-bandwidth) ranging were the factors that made this RFI particularly bad. The rest of the tracks are bistatic with Arecibo transmitting at S-band, but it looks like you are done from the 7-Day Schedule. Again, my apologies! It looks to me like there were ways to avoid this situation. best regards, Marty ------------------------------------------------------------ Martin A.
