Many of you are already familiar with the project of 122GHz transverter from Tim VK3CV. Now, he started a crowdfunding campaign. Prices are very reasonable and except transverter board (blank or assembled), you can also buy a chaparral style feed horn with a coupler or only conical horn.
All details about the campaign you can find on https://fundrazr.com/122GHzProject?ref=ab_5Gs3W2PhPXJ5Gs3W2PhPXJ
More info about the project you can find in “The 122G03 Transverter Users Group”
