Test of new 1296 MHz SSPA | |
| Tonda and Jirka OK1DCI tested our new 1296 MHz SSPA. They just connected all controls and tested own echos. Moon was at apogee but own echoes were strong. The output power was over 1000 W. More info and photos is here. | |

| Tonda and Vlada were QRV on 432 MHz for CE0/DF2ZF expedition, they QSOed them just before Moon set -22/-24 dB. It is our JT initial #40 and it was the first CE0 - OK QSO. | |

ARI CW EME contest | |
| Tonda and Vlada were QRV in ARI CW EME contest on 23 and 13 cm during the second orbit (Saturday evening till Sunday morning). They focused on new initials but haven't been very successful. Only two new initials, Ian G5WQ on 23 cm and Michael DL1YMK/A from his second QTH in JO33 on 13 cm. They were also QRV on 23 cm JT. 2 CW QSOs were made on 13 cm, 13 CW QSOs and 5 JT65 QSOs on 23 cm. | |

MW part of ARRL EME Contest 2010 | |
|
We continue on 6 cm till the end of the first orbit. 5 additional QSOs were made, total 10 QSOs in the contest. Vlada finished reconfiguration of our 10 GHz transvertor with new SSPA power supply (DB6NT design). We run about 35 W rf in the feed with current driver. We tested it on Sunday afternoon; 6 QSOs on 3 cm we made including SP3DRT as initial #53. Having nobody else but just noisy waterfall, we agreed with Brian, G4NSS a JT test on 3 cm. Surprisingly quite easy at 13:40 we made our first ever JT4G 3cm QSO at avg -25/-24 dB regardless wide spread at that time abt. 150Hz by Moonsked SW of GM4JJJ. Tnx to Joe, K1JT for really great SW. Later on measured Sun noise at 17.8 dB/SF82; Moon noise 2.8 dB and G/CS 5.3dB. After half a year of QRT it was quite happy 3cm afternoon on Sunday, and our first JT4G QSO on 3 cm with Brian G4NNS -25/-24 dB. The picture shows PC screen shot during our JT4G QSO with Brian.

MW part of ARRL EME Contest 2010 | |
| We were QRV in MW part of ARRL EME Contest 2010. As we will not be QRV in October part because of time collision with EU tropo contest we focus on 6 cm. We made 5 QSOs; SQ6OPG as intial #44. Moon noise was 1.3 dB; Sun 15.1 dB @ SF77; CS/G 4.4 dB. | |

| Tonda was QRV on 23 cm before ARRL MW contest. He was successful with Ross ZL1WN on 23 cm as new JT DXXC and also our JT ODX 17862 km. Tonda finish the QSO before sked started at 2.4° elevation only. | |

| Tonda was QRV on 432 MHz to test with Rolf OH0/DK2ZF. He didn't hear him but he made two JT65 QSO - EA3XU and G4YTL as new JT initial. | |

QRV on 23 cm and 9 cm. 8 CW QSO on 23 cm including JA1WQF, OK2DL, IK5QLO, GM4PMK (new DXCC) and N4PZ as initials so we reach #304. On 23 cm on JT65C we made 7 QSO including 4Z5LV, OK2DL, GM4PMK and PI9CAM as JT initials. On 9cm we add 5 QSOs, Paul WA6PY is our 9 cm initial #34. | |

| Tonda was QRV on 9 cm. He worked Hans OZ6OL, Eino OH2DG and as new initial and the first ES–OK 9 cm QSO Viljo ES5PC. After CW QSO with Viljo he worked him an JT4G as well. It is our first JT QSO on 3.4 GHz. | |

6 cm Activity Weekend - Sunday | |
| We have more time to experiment with SSB and JT4G during the second day of Activity Weekend. We add Henryk SP6GWN as CW #43, and Gerard PA0BAT as JT #4; all together 8 QSO - 4x CW, 1x SSB and 3x JT4G on Sunday. Many thanks to Peter, G3LTF for organizing this 6cm AW ! More than 20 different stations were active. | |

6 cm Activity Weekend - Saturday | |
| First day of July AW great activity on 6cm. We worked 18 stations regardless some obvious stations were not active due to other commitments. We were hrd at SP6GWN but he CWNR due to low pwr only about 10W. We succeeded with 4 new initials, Eino OH2DG as #39, Eric ON5TA as #40 and the 1st ON/OK 6 cm QSO, Guenter DL4MEA as #41 and Paul WA6PY as #42, DM field and CA US state. | |

| We were active on 6 cm as last check before 6 cm Activity Weekend. We QSO Gerard PA0BAT as initial #38 and Brian G4NNS. Both station has very nice signal. Then we tried JT4G QSO with Brian. Brian's signal was "speaker copy" but we were not able to decode each period. Moon was almost at Zenith so change of Doppler shift was quite fast. Also signal was spreaded about 75 Hz. It takes some time to finish QSO; JT4G initial #3 on 6 cm. | |

We were again QRV for Hermann expedition. He was in Finland, KP08TQ today. On 70 cm we decoded his signal for almost the whole two hours he was on, but have not succeeded. The signal was from -21 to -29 dB. The last two decodes were VV DEFEKT QSY 23 cm Then we QSY to 23 cm but we were not able to see him at all. Later on we read on HB9Q chat messages from Dan: 432 MHz - 11 06:17:58 HB9Q Dan OH/DL2NUD KP08 has problems with preamp! now QSY to 1296. 1296 MHz - 11 07:44:48 HB9Q Dan OH/DL2NUD has problem when using PA, PC goes down! trys to find and solve problem now! This makes it clear. | |

| We were QRV on 70 and 23 cm for Hermann DL2NUD expedition to LA, JQ90NA. Today we were successful and made JT QSO on both bands. In addition we CW QSO Bruce PY2BS on 1296 MHz as CW #298. | |

| We were QRV on 70 and 23 cm for Hermann DL2NUD expedition to trip of Europe, but heavy snow fall forced Hermann to QRT. Anyway, were successful. On 1296 MHz we made JT QSO with Filip SV1DNU and Derek ZS5Y, two new JT initials, DXCCs and Field. After that we made on CW Peter G3LTF and Hans OZ6OL. Thanks for nice QSOs! | |

New WEB pages | |
|
When we launched our web pages last year, we knew that it was just the first step. Today we introduce new dynamic (PHP and SQL) version that allows easier maintenance. We worked on it several months and albeit we know that it is not finish yet and likely never be we decided to switch to this version now. Few new functions and items have been already added and this will continue. I name amendment of photo galleries, mainly QSL skens and implementation of Field Maps as examples. The author of this web page version is again Petr OK1AXH. I would like to thank him for all the effort and patience with me. Maintenance of WEB pages is never-ending story, so please stay tuned. | |

| We tried to operate Dutch team at Mauritius 3B8EME on 432 MHz but we cannot see them on waterfall. We made three QSOs on 432 MHz on JT65B, new LO field. | |
