For the future

Let me congratulate the admin on running and maintaining the board , however I think most would agree adding the chat again would certainly increase traffic markedly , with the 6m season due the spotting use would be great , any chance ?

I've done tests using WSPR with another station 180km who I regularly decode 10dB lower than he's receiving me. We are both running the same power. Another test tonigh...
