The firmware/software upgrade to the Mark5A and Mark5B+ units has been carried out for mkv, mk5hb and mk5yg. The new version seems to have some compatibility issues with previously recorded modules - DirList gives all scan pointers as zero. For this reason, mk5streamhb has not been upgraded, in order to be able to easily read pre-March 19 modules (AUST19,AUST20,ohig)? The new version of fuseMk5 can work with the new UserDir size but has not been tested.
Info for observers: The upgrade changes the maximum number of scans that can be recorded onto a module from 2^10 to 2^16. Not everywhere has completed this though, so to maintain backwards compatibility you need to issue this command from the FS before starting a recording on an empty module
mk5=protect=off
mk5=reset=erase:s
This sets the scan list back to the short format with 2^10 scans maximum. This is necessary for all modules for the next few months, and critical for those sent off to Washington.
Also, can you include this message in the start/stop messages:
“The mark5B+ was upgraded 19/3/14 and is using mark5 v3.0.1 software, Amazon v16.37 firmware, and FPGAConfigVersion 1.08.”
Whole observatory moved to Vremya maser at approx 01.00 UT on Dec 2, 2013
Nov 10: Jack Paff reports:
Hi Jim,
I have completed servicing your antenna today which included greasing the AZ bullgear, El screw jack, all grease points outside and inside the pedestal. Also Applied UV protection to El screw jack cover. I would suggest you have someone test the antenna before the next experiment to make sure nothing has been disturbed during the servicing.
Regards
Jack Paff
LO became unlocked at different Az positions during r1610. Randall inspected the twister cable and found one had a kink. It also made a grinding noise if flexed. The problem was just below a hoop in the twister. That length of cable was suspected to be Heliax. It was the 100MHz cable to the LO. That length has been temporarily replaced with a piece of LMR400 that was also in the loom. The loss of LO lock problem seems to have gone away and the R1610YG experiment has continued. We should watch to see if LMR400 produces any more phase noise compared to the Heliax.
Randall confirms replacement cable is of same type as the original : LMR400. Photo of damaged cable attached.
