I just received an e-mail from Pete MM0TWX that the True Blue DX Club has ended. Including the nice TBDXC marathon that is. You can find more info as long as it is online on the website: https://www.tbdxc.net/
Pete came to the conclusion that amateurradio without using FT8 isn't possible for most HAMs. Only a few die hards are DXing with SSB/CW only. But it is just less as anticipated. It was a noble thought I think, but you can't fight the change in this hobby. It is how we DX these days....
I've never been a member but I really liked the marathon. I use whatever mode I'm able to use to DX. But I always prefer SSB. Unfortunately these days that is not always possible.
