SIM31 psk is very worth trying, because it’s much better than the standard PSK31. Today I worked VK6YM with 30W on 20 meter (received report -1dB) so it was also possible with 5W or less. I never worked VK before with standard PSK31. My antenna is only a 3 band HyEndFed wire antenna. So please more activity with SIM31 is desirable. Come on, give it a chance. Try your luck. Why using e.g. Digipan from the stone Age. When you join SIM31 on facebook you will be notified when there is new version software available.
With the PA beker Dutch contest I was number 51. I joined only a few hours on 40 meters. I saw my fellow blogger PE4BAS was number 9. Congrats!
