Arecibo Success
by Stu2 18 Apr '10

18 Apr '10

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. My report is at: http://www.stu2.net/wiki/index.php/MT_Arecibo 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! 73's Stu2 W7IY

Arecibo grumble
by Bob- W7LRD 18 Apr '10

18 Apr '10

Hello I have never uttered a controversial word on this bb. This Arecibo event presented us with a fantastic opportunity. I truly applaud those who set this event up and ran it. However-the object is to make contacts, and as many as possible in the allotted time. The CW procedures were laborious, 73's, multiple calls, excessive id'ing. They needed a top notch cw op. They used SSB, CW, then JT-65. I was waiting for them to try FM. Again, I am grateful for the chance to try to participate in this event. I learned a great deal in preparing and participating in the process. Their signal peaked at 569 using a 910 with 50feet of LMR400 to a 40 el CP yagi set for LHCP. I am sure the JT-65 mode gave flea powered stations an opportunity. As I hit this send button they have 40 minutes left. They might work a few more. grumble!!

AO 51 V/S
by Perry Yantis 18 Apr '10

The last pass of AO51 I did not hear anything on V/U so I switched to V/S and did hear an N8?? on one transmission, before they disappeared. I then called cq several times with good signal returns, but no one came back to me. Perry WB8OTH
