I've only seen RX reports, so far.
I was successful working KP4AO and it was quite a thrill for me. The first day, signals were weak. I didn't copy them on USB, but was able to hear them about 40-50% on CW. I called and called for the entire time. (CW) We were taking down the station of W4AD (SK), who enjoyed EME. My hope was to make one last contact from his back yard. Unfortunately, it didn't work out the first day.
On day 2, I set up a station my back yard. KP4AO was louder and I was able to copy USB, but the QSB always hit at the wrong time. Inevitably, I heard 599 and 'over'! When KP4AO switched to CW, I was able to copy them about 80% of the time with the QSB. Finally, at 16:25 Eastern, I worked them on CW with my 23 element K1FO yagi, TS-2K, preamp and 175W. I tried several different TX frequencies and was very persistent. The S-Meter never moved and it was like working a typical weak VHF signal.

Thanks to the gang at KP4AO for all their work. I really appreciate your efforts. My first QSO was on 2M with W5UN many years ago and this one was just as special. Again - thanks!
