- Operation of Ishioka antenna is now under interruption because of construction of operation building, and will resume after April.
- Modification of cryogenic dewar for QRFH system is being done.

Currently a prototype receiver is under revision and testing at Callisto, . A DBBC3 has arrived at Hobart and is installed. Successful tests at 16 Gbps. S/X mixed-mode observations possible with Hobart 12m.

Kashima 34m
Our 34m antenna is ready for observation for 3-14GHz 12.5 GHz frequency range.
And our DAS is capable of observation for 1GHz bandwidth at any frequency location in this frequency range.
Since our 34m antenna does not have fast slew speed as described in the VGOS specification, thus real improvement of geodetic parameter may not be gained with our station. But I believe we will be able to contribute at the development stage of the VGOS system.
So could you please consider some R&D experiment including slow slewing Kashima 34m antenna?
Another issue is data acquisition mode. The broadband observation at arbitrary frequency selection is only available with continuous 1GHz bandwidth observation, instead of multiple 32MHz bands.
I wish to request relaxing the restriction of observation mode so that includes 1 GHz bandwidth observation modes.
