Urgently seeking row data of JAISAT-1 satellite.
by Tanan Rangseeprom 10 Jul '19

10 Jul '19

Dear AMSAT member, Firstly, thanks for sending a congratulatory message to the Radio Amateur Society of Thailand under the Patronage of His Majesty the King (RAST) for the successful launch of the JAISAT-1 Satellite. The JAISAT-1 Project team has been informed by RAST President Dr Jakkree Hantongkom who had direct contacted to German Orbital Systems (GOS) which had informed him of problems relating to the beacon of the JAISAT-1 satellite and currently the JAISAT-1 satellite is in the process of the commissioning of various systems and getting them ready for use. GOS needs to use the beacon on the frequency of 435.700 MHz first before commissioning various systems for three satellites, namely JAISAT-1, LightSat and EXOCONNEXT, which are all using the Dstar One platform. In order for ease of control and to complete the commissioning of various functions it is necessary for GOS to use the Engineering Frequency of 435.700 MHz while the three satellites have orbits spaced apart allowing for GOS to adjust the operating frequencies separately. For JAISAT-1 the frequency is 435.325 MHz for as has been assigned by the IARU for the control of satellite operations. For the JAISAT-1 satellite, RAST has received funds from the NBTC's Broadcasting and Telecommunications Research and Development Fund for the Public Interest (BTFP) with support being made in periodic payments. According to the satellite progress report, RAST will be obliged to pay GOS a fee as a guarantee for successfully sending the satellite into space and to achieve this RAST needs to file a report to the BTFP in order to receive the funding for this payment. Consequently, RAST is making request for urgent assistance from AMSAT members around the world to listen for the JAISAT-1 Beacon signal on 435.700 MHz in GMSK Mobitex 4K8 mode, according to the advice from Mr Vlad Choreny as follows (Frames 1 in row 11): 11 (0x0B) - LightSat UHF1 12 (0x0C) - LightSat UHF2 41 (0x29) - JAISAT UHF1 42 (0x2A) - JAISAT UHF2 51 (0x33) - EXO connect UHF1 52 (0x34) - EXO connect UHF2 The Radio Amateur Society of Thailand (RAST) and the JAISAT-1 Project Team are urgently seeking row data that can be received from all packets worldwide. Please send Row data and KSS files to RAST by email at jaisatonetele(a)gmail.com so that RAST will be able to report the reception of signals from around the world to submit in a report to the BTFP to demonstrate that the GOS commissioning of all functions is complete up to and including the testing of the Linear Transponder in Mode-J that we will ask AMSAT members to test in the future. RAST therefore requests AMSAT members worldwide to gather information and send the details to RAST so that the society will be able to submit a report to the BTFP fund so that it will grant the final payment for GOS. With the JAISAT-1 launch, RAST has enabled AMSAT members worldwide to use the JAISAT-1 from now on. Please be informed accordingly. Sincerely and with respect Tanan Rangseeprom Project Manager of JAISAt-1

Neil Armstrong - Radio ham?
by Peter Green 10 Jul '19

10 Jul '19

Last evening I went to the premiere of the documentary film Armstrong, which charts a life of astronaut Neil Armstrong. Throughout the film it shows his home in Wapakoneta Ohio on numerous occasions throughout the film. Attached to this house is a mast with a beam antenna and in the garden are several vertical antennas. I cannot see any mention of Neil Armstrong being a radio ham so does anybody know if the current owner of the house is a radio ham or perhaps this is just a random house that happens to have a mast and antennas?

Re: [amsat-bb] PSAT2 PSK31 transponder operation
by Brad Schumacher 09 Jul '19

09 Jul '19

I have been able to activate the PSK31 transponder with as little as 20 watts when the satellite was at TCA and about 80 watts when closer to the horizon. I am using a Zero-Five 10-40GP vertical antenna which is about 27 feet in length. I learned that the PSK-31 will continue to run even when the SSTV is active. If the PSK-31 receive audio is kept between about 500 Hz to 1000 Hz and above about 2500 Hz it will not get interfered with from the SSTV transmission. In other words, set the 10 Meter uplink between 29.4785 and 29.4790 or between about 29.4805 and 29.4810 to stay out of the SSTV audio range.

Radio Carrying Case
by Kees van Oosbree 09 Jul '19

09 Jul '19

Hello, I've been looking for a new radio carrying case for my handheld radios. Right now I use an old camera bag to hold the radios, so then I can hold the antenna in one hand, and the speaker mic in the other hand. This has gotton complicated, however, because to adjust for doppler shift on my radios, I have to rummage around in my bag to to find the radios and have to push the buttons to change the frequency, which takes too much time. Does anybody have any ideas for a cheap way to hold the radios so they are easy to locate and don't take so much time to change the frequencies? 73 de KE0STO

PSAT2 PSK31 transponder operation
by Tomáš Urbanec 09 Jul '19

09 Jul '19

Hi all, after our return from european field day this weekend, we sorted out through all available receptions of PSAT2 telemetry and SSTV. As very valuable source we use the SatNOGS observations. There I have found several passes over US, were PSAT2 was transmitting because it sensed the PSK signals on uplink, and I have found two stations there and decoded their calls as W5SAT and K4KDR. Congrats gentlemen! If you can post the power/antenna used in experiments, it would be very valuable for us. Therefore we can state, that also the PSK31 uplink is in great shape and waiting for your further experiments. Tomas OK2PNQ and Ales OK2ALP
