From December 28, 2019 until January 01, 2020 the ISS send again pictures in Slow Scan Television. The images are always transmitted in Mode PD 120 on 145.800 MHz in Frequency Modulation. The following images were received with a 14 Element Yagi and decoded with MMSSTV software. More information about Amateur Radio on the ISS can be found on the ARISS website and the ARISS Blogspot.
First two pictures were received on December 30, 2019, no. 3 and 4 on December 31 (Expedition 61 – ARISS Series 15 Leonov). It looks like the last two were probably disturbed by unknown RF radiation.
It was a little cold that did not let me sleep. When I took a look at LiveCQ in the middle of the night I saw VP8EME (GD18bh) just calling CQ on 2m EME. The station was switched on quickly and the antenna turned to the moon. After 5 minutes the QSO was in the book. Thanks Mario for DXCC # 91 on 2m!
Just three days later on December 13, Kari OH2BC showed up on 2m from Madeira Island (IM12mm) using the callsign CR3EME. He uses 2x 9 Element Yagi and was received here with -28 dB in the peak. Kari was fighten against the noise produced by thousands of Christmas Lights but luckily he fished out my signal. DXCC # 92 on 144 for me could be celebrated.
The beautiful Zanzibar Island in Tanzania (AF-032 / KI93rv) was the destinationof Alex K2BB, Pavel UU0JR, Serg RT5D, Sasha UT7UV and Oleg US7UX. Under the call sign 5H3UN they were active on the Hf-bands, also using 5H3EME for 6m and 2m Moonbounce. For 2m EME they had two 10 element cross-yagi antennas with elevation, a Javornik II 144-28 transverter with dual channel RX – LNA, Odyssey II SDR transceiver and finally a 1kW solid state amplifier. After along night waiting for a signal at 01:10 UT 5H3EME came out of the noise and after two calls the QSO was in the log – DXCC # 90 on 2m. The goal is approaching …
Next step on the way to the 2m DXCC was the QSO with A21EME in Botswana (KG25wk) this morning October 21, 2019 on 2m via EME. The Team – Lins PA3CMC, John ZS6JON, Chris PA2CHR, Paul ZS6NK, Andrew ZS6AVH, Bernie ZS4TX, Sam HB9COG and Dan HB9CRQ activated 6m up to 10 GHz. The signal peaked up to -21 dB on my single 14 Element Yagi.
Completely unexpected and very late for the season, this afternoon the 2m band opened again via Sporadic E direction of the Iberian Peninsula. Within about 45 minutes, 6 EA and a CT station came into the log. Unfortunately again no stations in SSB or CW were heard or worked.
EA1NL, EA1UU, EA1YV, EB1DJ, EA2BFM, and EA4CRP were heard only.
Another one in the bag. Well known SSPA-designer Jim, W6PQL, was again active on 2m EME from Pico Island in the Azores (HM58rn). He used a pair of 2m20xp and one of his own designed SSPA’s. His signal was easily copied up to -23 dB here.
Back in August 2016 Lee, WW2DX and a Crew started to activate St. Paul Island (NA-094) on Hf and 2m EME as CY9C. At the second day of the DXpedition unfortunately gale force winds destroyed the antenna array and the 2m activity came to an abrup end.
Now, from July 31 to 08, 2019, CY9C is back on Hf and EME on 6m and 2m. Today I was lucky to work Lee on 2m EME for a new DXCC #87.
Also the month of July brought some nice Es openings to Asia as well to North America. Unfortunately, due to geographical reasons, the midwest of the USA could not be reached again from here. On July 24 at around 8:00 am my signal was heard from a VK3 station. Unfortunately, there was no 2-way-QSO this time.
In total, another three new DXCC entities could be added on 50 MHz in July: 4L/DL7ZM (Georgia), BA4MY (China) and JW7QIA (Svalbard). Thanks to David, DL7ZM and Peter, LA7QIA for their great DX-Peditions!
From July 29 until August 04, 2019 the ISS send again pictures in Slow Scan Television. The images are always transmitted in Mode PD 120 on 145.800 MHz in Frequency Modulation. The following images were received with a 14 Element Yagi and decoded with MMSSTV software. More information about Amateur Radio on the ISS can be found on the ARISS website and the ARISS Blogspot.
Pictures received between July 29 – July 31, 2019 (Expedition 60 – Series Inter-MAI-75).
Pictures received on August 01, 2019 (Remembering Owen Garriott W5LFL)
This remembers me to a QSO I had with W5LFL Owen on December 04, 1983, on 144 MHz SSB, when he was onboard the Spaceshuttle “Columbia”.
The day was quiet on 6m as the band opened up to Africa in the afternoon, July 23, 2019. I was busy watching for a TU2 station from Ivory Coast and a look to the MUF showed some red spots in southern France, means the MUF was above 140 MHz!
Time to switch to 144 MHz. Not too late and after some CQ-calls CT1FJW popped in, followed by other stations from Portugal. And there was another caller in between – could I trust my eyes? I thought my heart stopped beating. D41CV from Cape Verde was calling me! 15 second periodes for FT8-mode could be sooo long, would the propagations be stable enough to finish? Yes they were and then it was done: D41CV was worked on 144 MHz via Sporadic E plus Tropo Extension over an unbelievable distance of 4.966 km (3,086 mi), also setting a new Region I Distance Record! The signal of D41CV war copied for about less than 5 minutes.
If we have a closer look at the Hepburn Tropo Index, we can find the highest value of 10+ for the area west of Africa just between the Canary and Cape Verde Islands. This maritime tropospheric ducting widens the range of the massive Sporadic E Opening between Germany and EA8. What a lucky constellation today!
Thanks Monteverde Contest Team Club for calling and for this incredible QSO and Record!
Thanks to EI7GL who made a very nice analysis about this remarkable contact, see here.
Heard but not worked were CT1BYM -9, EA1HRR -6 and EA8TJ -7.
