FIRST TEST ON WORKBENCH IN THE SHACK
3cm in the "old mesh dish"
On 03-04-2015 we tested my Siemens RW1127 TWT at the " TWT testlab of Gerard PAØBAT" and measured 65W on 10GHz
Next step is rebuilding the 10GHz setup and put it in my new 3.7M Andrew dish. Own echoes must be strong now !!
3CM Rig with TWT and Power Supply in the dish, above the feed you see a small laser used to get the feed in the centre of the dish !
