Then you've read wrong. Whatever the problem was, it was clearly temporary as the most recent down link was fine. The UHF passes are pretty damn reliable, but they're not perfect.

http://an.rsl.wustl.edu/mer/merbrowser/bro...=res&m=MERA

Four CSV's at the bottom of this page are of UHF passes and have a data quality field, you can see many data dropouts within them.

Indeed, but the data quality field suggests that '1' could represent DSN issues:

QUOTE
"Flag which indicates data quality: (0 indicates valid, 1 indicates bad). Data may be flagged as 'bad' due either to telemetry indicating a bad receiver condition or to telemetry integrity checks indicating errors in telemetry record from ODY to the DSN containing the measurement data."

If it were a DSN issue, then we would likely have heard about problems with MRO, MEX and MODY downlink - not just Opportunity.

It would be most strange for a DSN issue to interject occasionally, within the downlink time of the packets from MER UHF passes.
