Fine and pretty small box  Time owned: 0 to 3 months
I have used it for one day (owned it some weeks) and only had one small software problem. Somewhere I read I could add my call to the end of the license number. That did not work, so I had to use the license number as is.

I have done the SOLT calibrations (Short, Open, Load and Transmission) several times. So I am now acquainted with it.

As a first test I have made a dual band J-pole antenna made from common electrical wire, balsa wood and tape, that did not work. ( https://web.archive.org/web/20150920073620/http://www.users.on.net/~endsodds/jpole.htm ) When seeing VNWA S11 curves I could see both resonances lay 13% to low. After shortening the elements, the resonances fell pretty close to the band centers and I am now using the antenna indoor.

(Next tests are components, crystal and RF-filter testing via the VNWA Testboard)
