How do you "create an auction" to sell something?

Posted By John Ott


I do not see a link or a method on this website on how to create or start an auction to sell something.  I read somewhere that it costs $10 for three auctions but I see no means in the Support Astromart section to pay that $10 and to get the ball rolling.

Can someone advise me please?

Hello Shawn,

About your homemade SDR-based radio telescope; You probably have an old C band Dish for an antenna? I'd be a curious, what's the frequency band of your SDR?
