EA5DOM (1525km) was coming in at -16dB S/N just now without the preamp! If I am going to copy anyone at greater range then tonight will be a good chance. I keep hoping to copy some USA 472kHz stations, but no luck so far. I may go and add the preamp overnight.
UPDATE 2352z: I have just switched to 472kHz WSPR RX only with the preamp. As tonight is my best chance this season so far, I am giving the RX the best chance too!
UPDATE Dec 20th 0014: Sod's Law says tonight WSPRnet will fall over. I need to check the overnight local logs carefully. t breakfast time tomorrow.
