APRS satellite dual hop
by Robert Bruninga 09 Nov '18

09 Nov '18

My bad. I misread it as a dual hop. The dual *s put in by some TNC's confused me. Here is how a 2 hop packet transmitted as ARISS,ARISS would look on the downlink in a normal TNC: PSAT,ARISS,RS0ISS* going one way or (least likely) RS0ISS,PSAT,ARISS* going the other (more possible) And remember, no one will find these on the ARISS or PSAT downlink pages because most likely only the first hop will be captured and the second hop will be rejected as a dupe. That is why everyone should always watch the downlink live if they want to capture one of those rare 2-hop APRS packets. HERE IS HOW TO DO IT: Challenges: Since PSAT has only a 0.2W transmitter, the ISS is simply never going to hear it. But the chance of PSAT hearing the ISS is 20 times better. SO the best chance of success is via ISS first then PSAT. But if they both hear the uplink packet, then PSAT will be transmitting at the same time ISS is and so a dual hop is blocked. So here is the best scenario for dual hop success: 1) Transmit stations via ARISS,ARISS on one continent hitting only ISS and NOT hitting PSAT at same time 2) PSAT in footprint of ISS but also over mostly ocean so it might hear ISS without lots of user QRM 4) Receiving station on a distant continent looking out over water towards PSAT. Then chances could be good. Notice, the transmitting stations can be any users as long as they are using the ARISS,ARISS path. So the only person that has to do any planning is simply coastal receiving stations. With both ISS and PSAT now operational, this would be a good time for all users to be using the transmit dual hop path of ARISS,ARISS to maximize someone else on some other continent receiving them! -----Original Message----- > Fm N0AN-10 To CQ Via PSAT*,ARISS* <UI pid=F0 Len=43 >[14:50:57] > =4206.15N/09402.30W`73 v.

Re: [amsat-bb] Making a phasing line for 70cm polarity switch
by Gregory Beat 09 Nov '18

09 Nov '18

You can see the 70cm phasing cabling in this photo. http://www.gulfalphaantennas.com/satellite%20yagi%20sub%20index.html Matching and Phasing Stubs for Two Antennas, by SV1BSX Common for satellite antennas for polarity switching. https://www.qsl.net/sv1bsx/antenna-pol/polarization.html#phase%20delay === Pete, WB4CGA (Gulf Alpha Antennas) retired in June 2015. However, in April 2016 Arrow Antennas LLC of Cheyenne, Wyoming acquired the rights to the designs of all Gulf Alpha VHF, UHF, and Satellite antennas as well as the rights to manufacture and sell those products. Parts inquiries should be submitted to Arrow Antennas LLC. http://www.arrowantennas.com/main/mail.html — Note from Pete, a few years ago: Important Notice about phasing cables and connectors on the Gulf Alpha circular polarity antennas. For a long time Gulf Alpha used LMR 400-75 as the cable of choice for the phasing of our satellite CPs. Because this cable is so stiff and the bends required to connect the cables on the 70cm antennas was very tight, the crimps were too stressed and sometimes the cable pulled out of the connector. We used the non crimp solder type for a while. These had their own problems in that they would twist and the braid would become totally disconnected. Again the cable would pull out of the connector. We are now shipping these antennas with LMR 240-75. This cable is smaller than it's larger counterpart and should solve the problem. All antennas including 2 meters will have top quality Type N four hole flange female connectors on the T match blocks. No more SO 239's and PL259's. Cable ends are prepared with Times MicroWave strip tools designed for this cable. === Date: Thu, 8 Nov 2018 08:26:19 -0800 From: Bob Hammond, WL7CQX To: amsat-bb(a)amsat.org Subject: [amsat-bb] Making a phasing line for 70cm polarity switch I would like to know how to make a 1/2 wave phasing line for my Gulf Alpha 70cm polarity switch. I've lost the original one while moving. I understand that using a SWR meter is how it's done but I'm not sure of the details. Is there a better way? I'd appreciate some help.

Each year, ARISS provides tens of thousands of students with learning opportunities about space technologies, communications, and much more through the exploration of Amateur Radio and space. ARISS has been pleased of late, to be one of many possibilities of interest to educators during NASA’s A Year of Education on Station, which celebrates an almost 12-month presence of a teacher aboard the ISS. The ARISS program connects students to astronauts on the ISS through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, other Amateur Radio global organizations and the worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering, and mathematics (STEM) and in Amateur Radio. Educators report regularly that student participation in the ARISS program stimulates interest in STEM subjects and STEM careers. One educator wrote, “Many of the middle school students who took part in and attended the ARISS contact have selected science courses in high school as a result of that contact.” Educators are setting up ham radio clubs in schools and learning centers because of students’ interest. ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and other STEM subjects. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for a once-in-a-lifetime opportunity for students. The proposal window opens October 1, 2018 and the proposal deadline is November 30, 2018. For proposal guidelines and forms and more details, visit: http://www.ariss.org/hosting-an-ariss-contact-in-the-us.html Proposal webinars for guidance and getting questions answered will be offered October 11 and October 23, 2018, both at 8 pm Eastern Time.

AO-91 or 92 problem receiving
by Burns Fisher 08 Nov '18

08 Nov '18

I could not find the earlier note about 91 or 92 receive problem, but I just remembered that I had trouble with 91 a few weeks ago and discovered that a network camera that I had observing my antenna was generating a strong signal right on the AO-91 downlink frequency. Ferrites on the CAT5 helped some, but not enough. So until I can examine it more, I power the camera off when I'm working 91. I found it using an HT and just noticed the squelch breaking as I tuned over the frequency. From then on it just used the HT as a probe. Narrowed it down to the network, and then had to do some unplugging to find the actual culprit. 73, Burns WB1FJ
