SatPC32, PSTRotator and 360 Degree Rotators
by John 28 Jul '19

28 Jul '19

Hi All, For various reasons, we use PSTRotator to control our rotator/elevator stack - mostly due to the need for IP control of the ERC-M, which SatPC32 doesn't seem to natively handle. It all works fine, for the most part, with the exception of the fact that I don't seem to be able to change my endstop value - normally this would be in the "Rotor" configuration settings, but since I'm leaving SatPC32 set to 'None' and having PSTRotator in 'Tracking' mode (it follows SatPC32's headings anyway), I can't see the option (it's not in the list) in order to pick South for my endstop instead of North. I can choose between 90 and 180 degree elevation (we use 180 as we only have 360 degrees of azimuth), but does anyone know how I can make SatPC32 understand the endstop being at the North instead of the South? Many thanks in advance, John (M5ET)

New Handheld for SO-50
by Kees van Oosbree 27 Jul '19

27 Jul '19

Hello, I've been working the birds for a while now, and I have been using only 2 Boafengs. I've realized they desense VERY easily on SO-50 and even AO-91 and 92. I have a band pass filter for the FOX sats, so I can hear my downlink. However, I still haven't figured out a way to get full duplex on SO-50. Are there any dual-band handhelds that can receive SO-50? 73 de KE0STO

For details, see: https://www.amsat.org/amsat-symposium/ +=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ --------------------------------------------------------------------- CAS-7B Launched and Operational On July 25, 2019, CAMSAT's CAS-7B satellite was successfully launched on the first orbital launch of iSpace's Hyperbola-1 rocket. CAS-7B is in a very low earth orbit with an apogee of 296 km and a perigee of 278 km. The inclination is 42.7 degrees. At this altitude, decay is expected by August 11th. CAS-7B carries a 100 mW CW telemetry beacon at 435.715 MHz and an FM transponder with an uplink of 145.900 MHz (16 kHz bandwidth, no tone required) and a downlink of 435.690 MHz (100 mW). Many QSOs around the world have been reported via the FM transponder. Reports indicate the transponder requires a considerable amount of EIRP to access and that the satellite is spinning fast causing rapid fading of signals. More information about CAS-7B can be found at https://www.amsat.org/camsat-cas-7b-is-ready-for-june-launch/ [ANS thanks CAMSAT and JA0CAW for the above information.] --------------------------------------------------------------------- Upcoming ARISS SSTV Events ARISS Russia plans to activate the MAI-75 SSTV experiment on July 29 with images starting at 13:15 UTC ending at 21:25 UTC, then again starting July 30 at 13:50 UTC ending 19:30 UTC. Downlink frequency is 145.800 MHz FM using the PD-120 SSTV mode. ARISS plans to commemorate Owen Garriott's outstanding accomplishments with ham radio in space during an ISS SSTV event starting 09:40 UTC on August 1 and ending 18:15 UTC on Aug 4. Downlink freq will be 145.800 MHz FM using the PD-120 SSTV mode. However, there is a possible switch out in images for SSTV event scheduled for August 1-4. This may result in planning an additional SSTV event for the end of August that would feature the Owen Garriott commemorative images at that time. We expect an update on this after July 26th [ANS thanks ARISS for the above information.] --------------------------------------------------------------------- AMSAT-Chile developing CESAR-1 FM / digital satellites AMSAT-CE is designing and building five satellites, to be used by radio amateurs around the world, which will allow a series of scientific experiments in the field of digital communications, as well as gravimetric and orbitgraphic studies. Of these five satellites, one will be the engineering prototype, three will be flight units, and the remaining one will be used to check or replicate on the ground the operation of the units that are in space. AMSAT-CE has also promoted the installation of three earth stations, in Iquique, Temuco and Pto. Montt. Technical characteristics *CESAR-1 is of microsat technonogy (cube shape, 23 cm per edge). *The satellite reception frequencies will be in the 145 MHz band (5 channels) and 1,575 MHz (GPS). *The satellite transmission frequencies will be in the 436 MHz band (2 channels). *The modulation will be FSK (AX.25 9.6 kbps) or narrowband FM. *The magnetic stabilization will be by permanent magnets. *It will have a magnetic brake (the rotation due to the photonic spin will be stopped by seven bars of hydrogen steel, which will cut lines of force from the earth's magnetic field). *The estimated useful life is 10 years. *The mass will be approximately 12 kg *The period will be 100 minutes (that's about 14 revolutions a day). *The satellite platform consists of 5 modules made of space aluminum AL6061-T6. *The electrical energy will be stored in a Saft NiCd battery, made up of 8 batteries of 7 Ah each. *The solar cells will be Spectrolab, triple junction (GalnP2-GaAs-Ge), or the like. Contributions of the CESAR-1 Project to the Country AMSAT-CE satellites will be added to the projects already undertaken by the Chilean Air Force (FASAT) and the University of Chile (SUCHAI), but they have as their main characteristic that they are the first ones that are being designed and built entirely in the country, which constitutes a huge challenge, and a scientific and technological contribution. Among the benefits that the country and the amateur radio can obtain from AMSAT-CE satellites are: - Education (interest young people in space radiocommunications) - Support in emergency situations - Scientific experimentation (in the frame for experiments) - Boosting a national aerospace industry - Experimentation with the Internet - National Amateur Radio Unit, and - International recognition for the country. Experiments The CESAR-1 satellite will have five main (E) experiments: E1 A digital transponder between two earth stations, to be used in real time, during the period in which both are being illuminated by the satellite (radio-packets in AX.25 at 9,600 kbps). E2 A digital transponder between two earth stations, to be used in deferred time, as an electronic message box (Store & forward with radio-packets in AX.25 at 9.6 kbps). E3 An analog repeater that will allow two earth stations that are being illuminated by the satellite to be linked, to broadcast audio (voice) in real time, in FM mode. E4 Communication between two terrestrial repeaters, with link to the satellite, which will allow long distance, but temporary, calls to low-power portable stations (voice, FM, 147 MHz access), and E5 An on-board GPS receiver, which will collect information for gravimetric and orbitgraphic research. The orbit of CESAR-1 will be low, polar and heliosynchronous (about 800 km high). *In any case, given the time elapsed, it is possible that both the experiments and the electronic part considered for them must be modernized. Cost of the Project and its Financing The cost of the project, in money, amounts to about USD 700,000 (necessary for the construction of five satellites, launch of one, implementation of two command and control stations, and three terrestrial repeaters). Of that amount, around USD 300,000 have already been contributed by external sponsors, and by members of the AMSAT-CE Foundation. However, we have not yet been able to obtain the financing of the remaining USD 400,000 Additionally, and conservatively, we estimate that the project requires some 36,000 man-hours of managers and specialists. Much of those 36,000 hours have already been or are being voluntarily contributed by the AMSAT-CE partners. Essentially, the monetary resources that are still missing are needed to finance the solar cells of CESAR-1, hire professional services to finish the construction of what is pending, and cover the costs of the tests and the first launch. Project status Although it is a radio amateur project, it does not cease to correspond to a professional and complex project. But the more than 20 years we have been working - without reaching the goal - have exhausted some of our partners, and this has generated a shortage of volunteers. It has not been easy to finish the first satellite - which should have flown in the late 1990s - because in Chile there is still not enough awareness about the possibilities offered by space activity to the country. Despite this, the construction of CESAR-1 is quite advanced (more than 70%): -5 mechanical satellite structures are built. -8 UHF transmitters are finished, and aligned in their working frequencies. -The sources of power are finished. -The receivers have an advance of 90%. -The GPS experiment has an advance of 70%. -In the OBC with its EDAC and RAM disk, the software needs to be refined. -The international coordination of frequencies in the ITU was concluded, but today it would have to be reactivated, for the time elapsed. -There are, yes, the photovoltaic cells, the assembly in Chile and the final tests (which will probably be done in Brazil). -It is also necessary to reactivate the obtaining of the pitcher.

Re: [amsat-bb] SatPC32, PSTRotator and 360 Degree Rotators

Hi Dave, The ERC unit runs via an IP serial server, so that we can access it from multiple parts of the site. We have a similar remote control mechanism for the rig, but that side all works fine. Still waiting for the next pass that goes through North, to see if SatPC32 now remembers the endstop as North!

When I select Yaesu GS232, it goes through the whole “you need to set up serversdx” palaver, which since I’m unable to use SDX (it doesn’t talk IP), seems a little counter intuitive. That said, it did make the option to set an endstop temporarily available, so hopefully by changing it, storing the configs and then choosing “None” again, it might remember the North endstop. My next pass in a few minutes will hopefully confirm. PST has no issue tracking the headings that SatPC32 displays even with the rotor set to none, so hopefully the temporary enable then disable will work. I’ll report back shortly.

It all works fine, for the most part, with the exception of the fact that I don't seem to be able to change my endstop value - normally this would be in the "Rotor" configuration settings, but since I'm leaving SatPC32 set to 'None' and having PSTRotator in 'Tracking' mode (it follows SatPC32's headings anyway), I can't see the option (it's not in the list) in order to pick South for my endstop instead of North. I can choose between 90 and 180 degree elevation (we use 180 as we only have 360 degrees of azimuth), but does anyone know how I can make SatPC32 understand the endstop being at the North instead of the South?

First DTMF grid!
by Robert Bruninga 27 Jul '19

27 Jul '19

Here is a video PY5LF recorded of his first successful DTMF Grid uplink: You do not hear his DTMF uplink but you hear the voice response and the APRS packet that results: https://www.facebook.com/py5lf/videos/2634132619939772/?t=0 That packet is a 3rd party APRS format for that grid report. It did not get picked up by either the PSAT2 telemetry or USER pages beacause of the 3 rd party format probably. Ill see if we can fix that.

Re Antenna Question
by Brad Smith 27 Jul '19

27 Jul '19

<"Louder" is more S-meter bars, or audibly louder?> <Is the horizon, for you, over a relatively unpopulated area? Do you live in a more populated area?> Audibly much louder at or near the horizon. I have never checked the S-meter while transmitting, but relied on what I hear in my earphones. Actually, on the D72, the S-meter only operates on receive and displays the power level on transmit, so it won't tell me what I need to know. Not super populated and I roam a lot and notice the same thing happening no matter where I go-as long as I have a pretty good view of the horizon. Brad Smith KC9UQR
