Do you need to buy a Serit tuner? Possibly, but look at the check list at the top of this page to find out https://wiki.batc.tv/Serit_tuner.
What's a version 2 MiniTiouner board and do you need one? Take a look here before you buy one https://wiki.batc.tv/MiniTiouner_hardware_Version_2
Note that you CANNOT use a Sharp or Eardatek NIM on this board - it will only take the new Serit tuner.
Full build instructions are available on the wiki page https://wiki.batc.tv/MiniTiouner_hardware_Version_2
Please check that you really need these items as we have an article appearing in Rad Com in 2 weeks time and it would be good to have some stock to enable newcomers to "get on the air" without having to wait for new stock - PCBs are not a problem with less than 1 week delivery from China but Serits are on 8 weeks plus.
