Hello again....and again :)) Nw i tried to reduce RBW to 1KHz but not so much difference..... Where to check first?
I have some home made switching circuit to switch between transverter and normal K2 work. Should be this the reason for non working? I will try to put it out and to measure the signal directly from pins on K2 main PCB... All kinds of sugestions are wellcome. The BATT PREFF setting in TX mode doesn't changed anything...
