I'd not spotted this one before, a Taiwanese project - YouTube graphic appears to show an Indian Launcher. PACE Satellite http://www.dlr.de/iaa.symp/Portaldata/49/Resources/dokumente/archiv5/0510P_… which says "... the frequency 145 MHz is selected for up and downlink communication." But 433 MHz CW/AX.25 is referred to at http://www.iaalab.ncku.edu.tw/pace/ PACEsat YouTube Video http://www.youtube.com/watch?v=u5gI7HqFbwc 73 Trevor M5AKA Daily Amateur Radio Email/RSS News: http://www.southgatearc.org/ Email Your News To: editor at southgatearc.org Or Upload Using Form At: http://www.southgatearc.org/news/your_news_1.htm ----

AO-7 was Rockin' tonight!
by Tim - N3TL 27 Jun '10

27 Jun '10

Hey everyone, I've never heard AO-7 so busy. I'm sure she has been - "in the old days," back in the 1970s when she was still new to orbit. But tonight on the pass that reached the W4G Field Day site about 0026 UTC, I heard more stations on AO-7 than I've heard in the two years I've been working the satellites - and I stayed in the CW portion of the passband! If CW was that busy, I suspect the SSB going on above 145.950 was even busier. Some may disagree (because I'm confident I'm not the only one who heard the "FMing"), but I was happy to hear the Grand Old Girl get such a workout. I promised the clubs from Athens, Ga., and Commerce, Ga. - who do a combined Field Day effort using the 1x1 call W4G - that I'd try to get them the 100-point satellite bonus. In 2009, I worked most of the Saturday and Sunday-morning FD passes as the W4G satellite station, and we did ok. For a number of reasons this year, I didn't commit to more than the time necessary to get them the bonus. I took a different tack with the station setup this year, too, because I wanted to show the folks how little gear is necessary to effectively work the satellites - even the highest-orbiting, oldest one in the amateur fleet. I used an FT-817ND as the transmit radio, and a Yaesu VR-500 handheld all-mode receiver as the receive radio. I connected both to my Elk antenna with a Diamond diplexer. In addition to hand-holding the Elk and manually tracking AO-7, I tuned for Doppler manually and used a straight key for CW. There was a lot going on during the pass, for sure. My goal was to show those folks that effective satellite communications doesn't require significant expense or so much equipment that portable operation is problematic at best. If you can connect an all-mode VHF/UHF receiver and an all-mode QRP rig that also covers VHF/UHF to an Elk or an Arrow handheld antenna, you only need to add headphones (to avoid feedback during full-duplex operation) and a key or microphone to work any of the FM or linear satellites. I dare say that if all the stations I heard on AO-7 tonight had been running no more than 5 watts into their antennas, the FMing probably wouldn't have been nearly so bad. Thanks from W4G to W5MSQ, N9AMW and W8DXA for the calls. I had a splitter cable from the headphone jack on the VR-500 to two sets of headphones, so several people got to listen to portions of the pass on the second set of headphones. It was fun seeing the looks on their faces as they heard CW arriving from orbit! Best of luck to everyone this Field Day! 73 and God Bless, Tim - N3TL Athens, Ga. - EM84ha

FT-817 charge?
by Robert Bruninga 26 Jun '10

I give up. How do you get the 817 to charge? Lost my manual. Charge menu is set for 10 hours. Is there something to push to tell it to get started? Bob

Finally my first HO-68 contacts
by Patrick Farcon 26 Jun '10

26 Jun '10

I had to share for the excitement was wonderful. I am usually unable to work many satellite passes of any kind during the week but by chance on the train ride home from work I noticed an 81 degree pass of HO-68 at its peak elevation this evening. I had tried before to make contacts on this satellite unsuccessfully and so far I have only tried FM. But with this pass so close to overhead I looked up what mode HO-68 would be in and in fact it was to be in FM mode at that time. So for the first time I decided to try a pass of a satellite at night and was overwhelmed to hear such clear signals. Receiving others was easier than getting the proper az/el combinations for uplink. Listening to my downlink helped immensely. I was absolutely floored that my first contact on HO-68 was YV1RDX from Venezuella. About 20 mins later and a few confirmed contacts I was so thrilled to have finally done it that I rushed to download the recording before the batteries that were low could possibly run out. I have only been working the satellites since about April or so and especially since antenna restrictions limit my activities. I am so hooked on this facet of the hobby and I can¹t believe it took about 17 years to get started! It really doesn¹t in fact take much...just two HT, an Arrow II antenna, a compass, a watch, and a digital recorder. Thanks to all that I made contact with and hope to see you all on the satellites soon! 73, Pat N2VYT FN20un

Thank you Patrick.
