Austin Texas QRP Group VIA or Vector Impedance Analyzer

The internet is brilliant if you want to have a go at building along with others even a couple thousand miles away. So having already had fun with the SDR2GO and the STM32SDR and softrocks I decided to have a go at the Vector Impedance Analyzer (VIA) which uses one of the STM32 development boards, a TFT touch display and some controllers.



I have just finished populating the VIA PCB and adding the headers for the 3 board 'stack' of the TFT, VIA PCB and STM32 dev board. Got to add some headers for the rotary controllers and then will box it all up.

I will probably use a dicast box but might make one from FR4.

Hope to get this done by the next Camb-Hams pye and pint in the White Horse, Barton next Wednesday 6th April.
