 Subject: EVNtech: First K-band e-EVN, first e-VLBI fringes to Mh
 
 
 Hi,
 
 Today we had an e-VLBI fringe test in K-band, prior to the F07K1
 ftp test. The participating telescopes were Cm, Jb2, Mc, Mh, and On60.
 The data rate was 256 Mbps. This was our first e-VLBI test at 1.cm,
 and the first one with Metsahovi.
 
 The test was a complete success, with fringes to all telescopes
 (see attached plot; note that Cm bandwidth is limited to 128 Mbps
 because of the microwave link). Onsala had a new dualpol K-band
 receiver which performed very well. The Jb and Cm sensitivities may
 have been a bit worse than expected, likely due to the windy weather
 or pointing.
 
 Regards,
 Zsolt
