- We replaced 1.6m dish with 2.4m Cassegrain optics of MARBLE1 station at NMIJ(Tsukuba) in March. Now we have two 2.4m dish at NICT(Koganei in Tokyo) and NMIJ( Tsukuba)

- Broadband observation sessions conducted in 2016 were performed with 2048Msps-1bit-4ch mode. Frequency array was:
Lower_edge ( Center Freq)=
3188MHz(3700), 4788MHz(5300), 9588MHz(10100), 12788MHz(13300)
5388MHz(5900), 6588MHz(7100), 8188MHz(8700), 10088MHz(10600)
3288MHz(3800), 5388MHz(5900), 8188MHz(8700), 10088MHz(10600) - If any station can do broadband fringe test observation (1GHz bandwidth for single channel), we are pleased to be a counterpart of the experiment. We will make correlation and provide the results. Frequency array can be arranged flexibly.
- Comments on Broadband Observation.
- Broadband Data acquisition has advantage in tolerance to RFI. It is preferable to be broadband at the stage on analog/digital conversion.
- I prepared a stuff on RFI for TOW meeting at Haystack. It tells our status of receiving signal and RFI conditions.
