Yuri, UT1FG/MM was on VO-52 Sunday morning from FM91. QSL route is Direct to his home QTH via QRZ.com. But keep in mind he is at sea many months at a time and won't get home for a while. This years sea adventures have just started and he is working his way down to the Caribbean.

As a ARRL Award card checker I have processed a number of his QSL cards. I do not have his QSL address. He will be the ONLY opportunity to work unpopulated wet grids. On VHF and Satellite. As a grid chaser, work 'em and worry about the QSL confirmation later. I am absolutely tickled that Yuri is back in range and operating.

April 19, 2009 To All RADIO AMATEURS BID: $ANS-109.5 Good DX via AO-7 This week AO-7 continued to surprise and delight amateur radio satellite operators with opportunities for good DX. On April 12 Tim, N3TL reported, "At 21:33 UTC today G1WPR answered my "CQ DX" on AO-7 Mode B. I was sending CW with the straight key I picked up for Straight Key Night on AO-51, and Terry called me in SSB so we completed a cross-mode QSO of more than a minute with a few exchanges. I am thrilled!" Tim also logged more trans-Atlantic AO-7 QSOs on April 16, "PH7PCF in the Netherlands answered my CW "CQ DX" with a hello in SSB. Then, a couple of minutes later, F2IL returned my CW in some CW from France. What a hoot!" The equipment at N3TL consists of a Yaesu FT-857D for TX and a Yaesu FT-817ND for RX (both used radios). He uses a Diamond MX-72H duplexer to connect them to a dual-band Elk log periodic, which is hand-held, manually tracking the satellites. Computer doppler control was done with Simon's HRD Satellite Tracker. Of the CW operation Tim described his setup, "I have the "CQ DX" call set up in a memory buffer on my FT-857D. But when somebody responds, the straight key takes over." Turning 35 years old on November 15, 2009 AO-7 still carries lots of amateur satellite traffic. Joe, K3SZH says Igor UA9CS Igor has now logged over 6000 QSOs via the bird. Also, this month Mike, KC9ELU has reached his 1000th QSO via AO-7. [ANS thanks Tim, N3TL and Joe, K3SZH for the above information] /EX W0YPT Silent Key AMSAT received the sad news that Telmer G. Olson, W0YPT became a silent key at age 91 this week. Telmer had worked the satellites from the earliest OSCARs to the modern satellites. Jerry, W0SAT remembered, "He elmered me and helped me get on the satellites in 1996. I knew him as a great friend that I called on for advice all the time. I used to visit him at his QTH and went to hamfests with him too. I and all the people who ever had contact with will always remember the many QSO,s and contacts we had with him."

Is the Elk Antenna better than a Arrow ant?? Thats my loaded question but not the subject of this email. How do you use a puter to tune your radios?? Newbie wants to know!! I didn't get a chance to try any of the birds tonite. Dialysis did a number on me today. I want to thank youu guys for the help you have given me when I ask about something. Its a learning experience with each diguest I get. Thanks!!! I've never heard anything on AO7 yet.

Newbie: Specific question re: Kenwood TM-D700A
by Robert Smith 19 Apr '09

19 Apr '09

Aloha I have tackled a new (older) radio for use in communicating with ISS, PCSAT and FM satellites. I am using the Kenwood TM-D700A in the non-TNC mode in conjunction with AGWPE, UISS and UIVIEW software (UIVIEW facilitating my Satgate). I have run a mini-din cable from the Kenwood to a Rascal mixing device then to an external soundcard. There are several reasons I have done this; foremost is the fact that UISS is so user friendly. Also, the signal coming off the minidin is supposed to be much cleaner than running the radio's speakers out (a telemetry requirement for many of the cubesats). This setup works for not only packets but other software types such as WXTOIMG. My apparent problem is that the signal does not appear to have high enough gain. For instance, when I view the sine wave in AGWPE it is minimal and cannot be adjusted by radio or computer volume. The percent volume indicator in WXTOIMG also lingers on the bottom "edge" at around 41 percent. Perhaps these indicators are irrelative, I am not sure. If someone has used the minidin out for such purposes and could educate me a bit I would be eternally grateful....(well amost HIHI). And yes, I realize that the radio itself is probably capable is doing many of these things on its own!! If interested in tutoring please contact me at dukenuke(a)pixi.com. Mahalo and 73 to everyone.

Hey everyone, Patrick, WD9EWK, and I had a pretty cool CW contact on AO-7 this evening. As far as I know (I'm confident Patrick will correct me if this is inaccurate), both of us were on full battery power and using handheld Elk antennas. My station included one FT-817ND for transmit (at 5 watts out) and another for receive, and each was running on its internal battery pack. I pulled the plug on my Acer netbook and let it do the Doppler tuning on its internal battery pack. I connected both radios to the Elk with a Diamond duplexer, and used the straight key I picked up for Straight Key Night this year. Patrick was a solid 579 when he called me, and he worked AJ9K after our contact. And unlike me, I believe he is still manually tuning for Doppler. I confess that I've gotten spoiled very quickly by the computer's assistance in that regard. I believe these are Patrick's first contacts on Grand Old AO-7. Congratulations to him. Here's to many more contacts with our "flea power" portable stations. 73 to all, Tim - N3TL

But the fade is not very wide so the vast majority of time it works just fine.

Re: Homebrew Elk-style 14/435 mhz log periodic for sats?
by Oscar Diez 18 Apr '09

18 Apr '09

Hi Bill, for a homemade "Elk" style log-perodic antenna covering both the 2m and 70cm bands see this homemade antenna (with bilingual instructions in German and English) link: http://www.radio-foto.net/radio/lpdadual.pdf The text above is mostly self explaining and very simple and cheap to construct with some basic tools on hand. This antenna is slightly larger than the Elk (15 inch longer boom length) which results even in a higher gain then the original Elk design. Maybe this gives some desired extra punch for eventual indoor operation. Good luck, Oscar DJ0MY

Hi Danny You did a good job on the link budget. Jan King is the author and he will comment if you send him a copy. Here are my comments. 1. Patch antennas are hard to put on a cubesat because of their size. 2. If you fly dipoles they have very deep lobes of the end of the ends and will cause deep fades when the antenna alimented off the ends. 3. The ground antenna when at 5 degrees elevation look into the warm earth i.e. 290 deg K For a reality check go copy AO 51. Copy the telemetry beacon. It uses FSK modulation and if you chose GMSK it is several db improvement over FSK. The antenna are turnstile with 2 db gain circular polarized. AO-51 keeps the antennas nadir pointing so there is very little fading due to polarization misalignments and this is a challenge on 10 cm cube. If you make it to the cube sat conference at San Louis Obispo look me up I am 6 ft tall with red hair and 64 years old.

current ISS pass
by David J 18 Apr '09

18 Apr '09

I'm a bit confused here. I'm currently receiving APRS signals from the ISS on 145.800 instead of 145.825 MHz. In addition, I've just updated my keps on Satscape and I see the ISS footprint way east of my location here in Florida. I appear to be having an overhead pass or close to it. I don't have time to really run this down. Does anyone have an explanation. Is this happening to anyone else? Dave, AA4KN
