First day WSPRing.

This this is my first day on WSPR, RX only (for the moment)
So I've been having a listen around the bands.

I've got a question, how can I check the accuracy of my RX/TX frequency ?

Thinking out loud , next week there is a very big meteor shower (Perseid), with some long bursts, It could be an idea have a 'play' on the high bands. The peak is on the morning of the 12th August, But it will be active a few days before and after.

Best 73
