8 SSTV pictures received from ISS Space Station.

Hello All, Russian commander Pavel is testing the SSTV equipment aboard the ISS Space Station. The latest ISS SSTV pics where sended on the 145.800Mhz downlink frequency. There are some equipment problems so it is only switched on when Pavel is near the transceiver, mostly in his presleep time on the passes (for his friends) in Moscow. You can see the 8 ISS SSTV pictures on my website: http://www.pd0rkc.com In case someone have more ISS SSTV pics please send to: skyman(a)hetnet.nl 73's Cor PD0RKC ISS info: http://www.pd0rkc.com

Cheap LEO antennas
by Grant Zehr 18 Aug '06

18 Aug '06

I would also stongly recommend the "Cheap Yagi" design, especially for 435 mc. band. I used a 3/4 square wood boom and a full length 435 mc. "AMSAT" cheap yagi design. I built one for my AO-40 uplink and another for LEO's both worked great. Sand the wood so it is nice and smooth. If you can find a drill press you will have nicely squared elements. To paint it I use a white "exterior wood primer" from the hardware store which is for priming the wood surfaces on the outside of your house. If you get the good kind, it takes 2-3 days to dry completely. Then I painted it with aluminum colored enamel ("rustoleum" or similar). I picked up some Coaxial cables at a flea market with BNC connectors, cut one in half and used that 2 antenna drive cables. From the ground it looks just like a "store bought" antenna and more important it really lasts. My LEO antenna has been up for about three years and still looks like new. The other thing is to be really careful about letting water get into the coax. Just use some caulking and be sure to loop your coax near the driven element to form a "drip loop". Gravity will keep things dry. Don't crush the wood while tightening the mounting bracket. It is easy to clip the driven element to tune the SWR. If you have time use a file to trim it when you get close to the best SWR. This is a GREAT antenna, just use exterior primer and enamel paint to protect it. I prefer wood to PVC (and I have used PVC for other projects). I used it today to work EB1FG on FO-29 on an east coast pass which peaked at less than 1 degree elevation here! Grant Zehr AA9LC

FO-29 turns 10
by ANTHONY JAPHA 17 Aug '06

17 Aug '06

FO-29 is a wonderful, reliable bird. Here on the east coast, it's possible to work DX (Eu.) with low power and the equivalent of an Arrow ant. (My own experience is that the Arrow doesn't do well because of overload on 70cm, but when put on 2 booms--2 mtrs on 1, and 70cm on the other-- using 2 small tripods, it's usually fine.) On a recent trip to several QTHs up and down the west coast, FO-29 was almost always heard from predicted AOS to LOS, though without much activity. Sometimes a preamp was used, which made life easier, but that's by no means essential for routine QSOs. A big disappointment on that trip was AO-7, which, even when it's in mode B (I didn't have mode A capability operating portable at oceanside QTHs), was nearly impossible to get into. I was using 5 watts on both FO-29 and AO-7 from excellent QTHs. I was not able to make a single QSO on AO-7, though a few stations were heard. I have seen reports of good success with 5 watts and small antennas on AO-7, but I can't verify that experience. I'd appreciate your thoughts on whether I should buy a 20 watt amp. and try that on AO-7. Long live FO-29! 73, Tony, N2UN

Re: NEW GRIDS !!! XE2AT

Hi! > Dear boys and girls Bernardo XE2HWB will make a trip to DL27-37 from 17th to > 20th of this month, is in Baja California for the 10GHZ and UP contest, I > sent a small 6 ele yagi and he will be in AO51 from those new grids. > I think he will try to be in DL28 after the 20th so keep in touch, I will > advise to BB about the status from Bernardo. I talked with Bernardo on AO-51 this morning, and he said he will be in DL37 (a desert in southern Baja California) tomorrow. He previously mentioned via e-mail his plans to be on from there and other grids in the area (DL27, DL28, and DL38) between Friday 18th and Monday 21st, saying he would spend the most time in DL27 and DL37 with maybe one pass each for DL28 and DL38. All of the satellite work will be via AO-51. The rest of the weekend will be spent working the ARRL 10 GHz and Up contest from down there. Bernardo's English is pretty good, but please use the phonetic alphabet when calling him - or call him in Spanish. :-) He has antennas and a new duplexer for his satellite work, in addition to what XE2AT sent him, so hopefully he can show up from those spots. 73!
