Plane mechanics has been modified in order to keep the same hybrid box for everybody.
M. Pauluzzi has requested a couple of hybrids to qualify the assembly at Perugia. t has been decided to give him old hybrids from AMS-01 because teh new hybrids v1.8 have not been tested. The main worries came from the capacitances. This week this capacitances should be definitively tested and approved. The delivery should be done in 8-12 weeks. Optionally half of them should be here at the end of May and the rest before August.
Omnetics and Airborne have not sent their offers about conectors
HCC for the "traditional" hybrid should be sent to production at the end of this week (24th March). Giovanni will supervise the design next thursday at Viareggio.

First offer for a nice and needed oscilloscope demanded to HP (~22500 CHF). IT has been suggested also to contact Tektronic.
