Saturday on 70 cm | |
| Not being in contest we set up our aim to QSO IS0 expedition and some new stations. We finnished with 3 new initials; IS0/OK5EME, OH2PO and RW3WR on JT65B. | |

Sunday orbit of MW part of ARRL EME contest 2011 | |
|
We finish 6 QSOs on 3 cm out of contest on Sunday. Manfred DL7YC was our initial, he transmits with horizontal polarisation and this was his very first EME QSO on 3 cm. We were heard by JA1WQF with 1.8 m dish, but his window was closed by trees, so something for next time. After QSY to 13 cm, 4 QSOs bring us two new initials, ON5TA and PA7JB. Then QSY back to 24 GHz and finish the fourth QSO in contest, All together 4 x 400 = 1600 points. There was Indian Summer both days. | |

Saturday orbit of MW part of ARRL EME contest 2011 | |
|
We have to repair azimuth engine control in the night at the first. We were on 13 cm for a short while, no new inital for us. We QSY to 3 cm where we expected UR7D (3.7 m dish & 50W). We QSOes them easy 559/559. We made three more QSOs on 3 cm. We QSY to 24 GHz and finished 3 contest QSOs. We selected 24 GHz as the contest band this year. We lost motivation to often change band and risk demage of rigs by some mistake in hurry when category 2.3 GHz and up was canceled. | |

Second JT4 test on 24 GHz | |
|
We tested again JT4G contact with Brian G4NNS on 24 GHz. Brioan was able to decode or signal in one period. There was a big Doppler shift and signal spread at the time of the test. Humidity drop below 60 %, Moon noise 1.9 dB (elevation 37 deg.); Sun noise 13.6 dB *SF 155 at elevation 39 deg.) and G/CS 2.7 dB. Picture below shows our JT4G signal decoded at Brian station.

7P8EME on 70 cm - QSO done. | |
| Today, with antenna beaming west - out from interference - Tonda was able to finish QSO with 7P8EME after his first call. Their signal was strongest on vertical polarization -18dB. | |

7P8EME was QRV on 70 cm, but ... | |
| 7P8EME was QRV on 70 cm, but we cannot find their signal in very strong interference from DVB-T transmitter east from our QTH. | |

Waiting for 7P8EME expedition on 70 cm. | |
| 7P8EME was not QRV but five new initial on JT65 were made, RK9AT, PE1RDP, EA5CJ, PY2BS and PA0PLY. | |

JT4G test on 24 GHz. | |
|
Signal was very weak with terribly wide spread, no decode in JT4G test with Brian on 24 GHz today morning. Weak signals were visible on screen on both sides, but no decode at all.
These are the condition when the sked is not worth to plan: – Apogee in summertime is the worst choice possible - Nighttime in summertime is the bad choice as well. High atmosphere humidity obvious in summertime brings too high additional attenuation along the slant path, esp. at low Moon’s elevation. – High spread impacts seriously weak signal readability Some more information and screen shot could be find at Signal records - 24 GHz - Technical Issues section. | |

7P8EME QRV on 23 cm. | |
|
We received an envelop with AWARDs from European EME contest and DUBUS 3/2011 with contest results today morning. Awards are scanned in Achievements - Awards section. Tonda was successful in JT65 QSO with 7P8HP as new DXCC on 23 cm at the evening. Rotatable linear feed (EIA) was used, the strongest signal was on vertical polarization. Then Tonda swap to circular septum feed and finish CW and JT65 QSOs with Emil OK1CS. | |

New WEB structure | |
|
Today the WEB were swapped to new structure. New menu Signal Records contains screen shots, signal records and other articles. New structure also allows to switch to Czech version, this is available at right bottom corner of each screen.
I would like to apology to our Czech colleagues, that Czech version did not come together with English one some year ago. Even now not all original text are not translated yet. We will continue to translate them soon. Please inform us if you find any broken link or missing page. Last but not least, I would like to thank Petr OK1AXH who spent enormous time to create this web. | |

| Again QRV, today on 24 GHz. New initial with DL7YC as #9. It was cloudy, high humidity, Sun noise measured on SDR-14 was 14 dB ( SF 100), Moon noise 1.7 dB, G/CS 3.2 dB. | |

| Tonda and Vlada were QRV on 6 cm after a while. We have skeds with S59DCD and 9A5AA. Both skeds were succesful. Two new DXCC on 6 cm, that's great. | |
