Well last night was certainly a surprise. never expected the QRP beacon to be heard that well.

VA7JX heard me as soon as I turned it on, a distance of about 500km in full daylight!

To be totally honest, it looks like my little post amp after the U3s is putting out a bit more power than I first thought. Rather than the estimated 25 mW EIRP, it looks like it might be closer to 100mW. Still surprising.

If I have time today, I will fool with the post amp a bit more. I hope to get up to the 250 mW EIRP range.

WSPR stations I heard last night:

KB5NJD
W0IOO
K0HW
N6LF
VE7BDQ
VE7VV
