		Medicina station report to EVN TOG meeting


These items cover the period April 2004 - November 2004:

1) Mark5:

	-Hard disks were purchased in order to assemble new modules before the May and November sessions. 
	18 2TB(8x250GB) were added to the VLBI network.
	By now a complete set of 5 960GB and 21 2TB 8-packs has been made available, for a total storage capacity of 
	41840GB for astronomy and 8988 for geodynamic data. 24 more enclosures are also ready at the station to 
	be filled with disks. The total cost sustained by the institute was 44296 euros.
	
	-Mark5 software version installed: 2.6.3x
	
	-Mark5 firmware version: 0xb8,0x19

2) Field System:

	-Field System version installed: 9.7.1. Minor release 9.7.2 will be installed after the third VLBI 
	session is over.

3) E-VLBI:

	-IRA and the regional government signed an agreement under which the government will pay for the 
	installation and connection of a fiber optic link at 1Gb/sec between Medicina and Bologna. 
	The work is forseen to start at the beggining of 2005 and to be completed within the summer.

4) Receivers:

	-New cryogenics Low Noise Amplifiers development is in progress. At the moment we have 22GHz hybrid 
	GaAs LNAs and InP MMIC chips. The last ones have to be bonded and embedded into connectorized enclosures. 
	The design of 28-40GHz, 35-48GHz and W band (around 90GHz) LNAs is in progress by using the monolitic 
	solution with InP technology. The delivery of the chips is expected for spring 2006. A 4.3-5.8GHz 
	hybrid LNA is under construction as well.

5) Hardware
	-An hardware upgrade of the polarimetric system has been completed and a software package to produce 
	rasterized scan observations is under test.

6) Maintenance:
	
	-H-maser was serviced for periodic maintenance. It was also synchronized before the beggining of 
	the Novemeber session.

7) Sardinia Radio Telescope staus:

	-The foundation construction - the cement is being cast.

	-The steel parts construction of the SRT new antenna is going on: wheels and rail are ready, along with 
	gears. Alidade parts are also almost completed. 

	-The active surface system is under construction along with the panels forming the primary mirror.

	-A 7-horn multifeed receiver at 18-26GHz is in progress, together with a spectrometric back-end system.

	-The commissioning of the antenna servo system, the panels for subreflector, the mirrors for the beamwaveguide 
	will be soon underway

	-All the others servo systems constructions (primary focus receivers, subreflector, rotator drum, beamwaveguide 
	rotating turret) are in progress.
