June 4th 2011 | ||
EU EME contest on 1296 MHz | ||
| We worked 79 CW QSOs (including 11 initial) in the contest during the weekend. In additional we heard G3LQR, IK3COJ, JA1WQF, LX1DB and PA7JB. We worked out of contest on JT65C on 4.6. LU1CGB -27/-18 as JT #90 and on 5.6. PE1HNG. | ||

June 2nd 2011 | ||
LY expedition on 13 cm. | ||
| Tonda was on 13 cm and worked LY/DL1YMK and WW2R. Later on during test of new SSPA he also operates on JT65 G4BAO as JT# 4, LY/DL1YMK -18/O as #5, PA3DZL -20/-15 as #6 and W5LUA -10/-10 as #7. We heard WW2R -14m but only QRZ. | ||
| ||
May 29th 2011 | ||
| ||
| Tonda was QRV on 13 cm and worked Michael LY/DL1YMK, SM4IVE and SM3BYA, three new initials and new DXCC. | ||
| ||
May 28th 2011 | ||
| ||
| Tonda was QRV on 23 cm and worked LY/DL1YMK as #310 and new DXCC and HB9BBD. | ||
| ||
May 22nd 2011 | ||
South America on 9 cm. | ||
| On 9 cm on Sun, May 22 worked at 01:24 PY1KK 559/559 #36, GG field and the 1st PY - OK 9 cm QSO.Bruce used 4 m dish and 200 W at feeder. His signal was 15 – 20 dB over noise here. | ||
| ||
May 14th 2011 | ||
| ||
| We were shortly QRV on 23 cm, worked JT65C ZS6WAB as JT #88 and OK1YK as JT #89. Nil in the sked with RA0ACM. Later CW QSO with Mirek OK1YK #309. | ||
| ||
May 13th 2011 | ||
24 GHz test | ||
|
We widened the dish beam-width 1.8-times when under-illuminating the dish by the new feed (equivalent to a dish ≈ 2.5m with f/D≈0.7). Measured Sun 14.6 dB (SF 92); G/CS 3.5 dB and Moon 2.4 dB (later ≈2.0dB when clouds). Worked LX1DB O/O; DF1OI O/O; G4NNS O/O and at F2CT M/O as #7 and 1st F-OK 24 GHz QSO. Improvement of RX performance by widening the beam was verified in opposite TX way by Willi, LX1DB, who mentioned almost double spread of our signal compared with previous narrow beam. The same effect was observed on our own echoes. We have had own echoes till elevation of 5.5 deg., when echoes were finally swallowed by humid atmosphere, though the Moon was still visible.

European EME 13 cm contest - Sunday | ||
| Worked another 4 station in contest , 40 stations in contest in total. | ||
| ||
May 7th 2011 | ||
European EME 13 cm contest - Saturday | ||
| Worked 36 stations including new initials: S50C as #106; IK3GHY as #107 and N8UO as #108. Detail in LOGs & Statistics section. | ||
| ||
May 6th 2011 | ||
European EME 13 cm contest preparation | ||
| We worked Viljo, ES5PC when testing equipment for the contest. | ||
| ||
May 4th 2011 | ||
24 GHz test with G4NNS. | ||
|
24 GHz test with G4NNS. Brian signal as quite weak at the beginning, later was stronger. Very nice QSO, thanks. We repeated QSO with Brian, then at 14:27 heard W5LUA O but lost his signal. The day was closed with QSO with DF0OI. Brian signal on SDR 14 waterfall when became stronger
More figures at Signal Records 24 GHz. | ||

EU EME contest on 6 cm, the second orbit | ||
| Tonda added two additional QSOs on 6 cm, F1PYR as initial and the second QSO with W5LUA on Sunday. It was very nice contest, two new initials on 6 cm. We have 20 valid QSOs on 6 cm in the contest, this is more that we sometimes made in EU tropo contest! | ||
| ||
April 30th 2011 | ||
EU EME contest on 6 cm | ||
| Tonda and Vlada were QRV during EU EME contest on 6 cm. Moon noise was about 1.2 dB, that is nice as was close to New Moon and Moon was near to Apogee. There was thunder storm Saturday afternoon. All together 19 valid QSO in contest by the end of the orbit. | ||
| ||
April 10th 2011 | ||
EU EME contest on 3.4 GHz | ||
|
We continued in contest on 9 cm. We finished with total 17 QSOs. Unfortunately no new initial.
We also watched PJ4X expedition on 432 MHz, but no trace was found in our man-made noise background on 70cm. We found it as a hard job even for the biggest guns. During time spent on 432 MHz we worked G4FUF, G4EZP and I1PIK -22/O but ncfm for TX failure at I1PIK. | ||
| ||
April 9th 2011 | ||
EU EME contest on 3.4 GHz | ||
| Good activity on 3.4 GHz in contest. Worked 13 QSos in the first orbit. | ||
| ||
March 20th 2011 | ||
| ||
We were QRV on 24 GHz and on 22:55 LX1DB 559/569 followed by delighting SSB 55/54 (moisture, Moon in clouds, Moon noise 2.4 dB). Screenshot shows LX1DB signal on 24 GHz.
Later nil in sked with F2CT (Guy surprisingly found Moon behind trees). Otherwise clear sky, ambient temperature below 0°C, Moon 2.6 dB. Later tried JT4G own echoes at predicted spread 190 Hz. Test brought clear evidence of a digi QSO feasibility, at least at lower spread. We would be happy to test with anyone else on 24 GHz. Picture below shows JT4G echoes on 24 GHz.

In sked Guy, F2CT on 24 GHz | ||
| In sked Guy, F2CT. He heard us as his 1st EME 24 GHz signal, but very weak. | ||
| ||
March 18th 2011 | ||
| ||
| On 10 GHz at 21:54 repeated QSO with 9A5AA O/O and at 22:09 F2CT M/O #59. Moon noise was 3.0 dB (full Moon). | ||
| ||
March 15th 2011 | ||
| ||
| We worked on 10 GHz at 19:03 perfect 2xSSB with LX1DB 55/55 at Doppler about zero and finally at 19:44, when Dragan repaired TX, 9A5AA O/O as initial #58 and DXCC #23 on 10 GHz. | ||
