Azimuth cable wrap
The IF cables in the azimuth twister, below the turning, head have been replaced/rerouted. They still need to be checked for OK laying throughout the entire wrap, from + to - limit. As a result, the emergency stop is pressed. The antenna should not be moved until this check is done.
New cables
Yesterday we installed some new cables.
Mark5B firmware upgrade
After upadting the mark5B software (following the instructions found at http://www.haystack.mit.edu/tech/vlbi/mark5/downloads/Mark5BUpdate.pdf) problems were still seen using scan_check on the 6 TB SATA drives. To correct this, I ipgraded the Mark5B firmware from 12.41 to 15.30, following Dan Smythe's instructions. Several environment variables had to be set and have been included in oper's .bashrc file.
export STREAMSTOR_BIB_PATH=/usr/local/src/streamstor/linux/bib
export SS=/usr/local/streamstor/linux
export PATH=$PATH:/usr/local/bin/streamstor/
Once these were set, the flash_upgrade was carried out by
cd /usr/local/src/streamstor/linux/lib/gcc_v3/util/
./flash_upgrade
This will need to be done for each of the mark5B recorders.
RF cross-over switch test
Confirmed, by talking over the serial port to RF unit, that S and X-band cross-over switches can be controlled and appear to work as expected. Test carried out by observing how amplitude of a tone changed when switches were toggled.
