40m WSPR overnight

As you will recall, my antenna on 40m is very low and not that efficient: it is just a 10/20/40m Par end-fed with an average height above ground of 4-5m at most. Last night I was on 2W. I hate to think how low the ERP would have been on 40m!

Overnight 17 unique stations spotted me with best DX AE2EA (5654km). Even with a low and inefficient 40m antenna, WSPR still works well!
