1296 MHz: Linear rotatable feed, on 05.03. at 16:11 UA3TCF -20/-13 #108* and at 16:23 UA3TCF O/539 #328 and LO field. Alex has 2.2m dish, linear vertical feed and PA 100 W.

3400 MHz: Before Dubus contest on Fri 02.03. at 15:00 wkd PA3DZL O/O #38, 17:20 DL7YC 549/549 #39, 20:48 W5LUA 569/569 and at 22:01 K5GW 569/559. JT65C at 21:18 PA3DZL -23/-23 #2* and 23:16 W5LUA -19/O #3* and JT ODX 8567 km. In contest wkd on Sat 03.03. at 00:06 OZ6OL 549/549, 00:19 S59DCD 539/539, 00:27 G3LTF 559/559, 00:36 VE6TA 549/559, 00:45 WA6PY 549/559, 00:55 K2UYH O/O, 01:01 K5GW 579/579, 01:21 ES5PC 559/559, 12:14 OK1CA 569/569, 14:07 PA3DZL 539/559, 14:18 PA0BAT 559/559, 15:20 DL1YMK 559/539, 17:59 S57NML O/O, 18:22 DL7YC 559/549, 18:39 OH2DG 569/569, 21:12 WA9FWD O/O and 21:59 W5LUA 569/569. On Sun 04.03. added at 00:16 WD5AGO 549/339 for the total 18 QSOs. Hrd was WW2R O and LA8LF 559 (unfortunately Anders eceiving mistakenly on image QRG of 3110 MHz with great Sun and Moon noise figures !). On Mon 05.03. wkd at 19:16 LZ1DX 549/559 and before the sked at 19:24 LA8LF 559/559,#41,1st LA-OK 9 cm easy QSO after Anders retuned his transverter to correct 3400 MHz. With JT65C wkd at 20:20 ES5PC -16/-26 and 20:27 LZ1DX -21/-23 #4*.

5760 MHz: On 05.03.at 18:05 DL7YC 559/559 #54. Great signal from 2.4m off-set dish.

24 GHz:

On Tue 06.03. random at 18:06 LX1DB 559/569. In sked with OZ1FF hrd very weak signals both sides but QSO not completed. Kjeld uses 1.8 m off-set dish and very similar trx design, but only one 10W DB6NT SSPA . At clear sky and -2°C we measured “close” Moon noise up to 2,6 dB. Next sked on Thu 08.03. was again preceded at 21:33 with LX1DB 559/569. Willi asked SSB, but the mike on our side refused to modulate TX properly, sri. In sked finally wkd at 23:30 OZ1FF M/M #10 as 1st OZ-OK on 24 GHz. Signals were hard to copy due to big spread (over 200Hz predicted as maximun of the day, hi). QSO was finalized when clouds cleared the sky at el 36°/30°, regardless RH rised close to 90%. Moon noise in clouds decreased to 2.2 dB and later at clear sky returned to 2.5 dB. Whole the time Willi, LX1DB watched OZ1FF signal at O level, while we paid a penalty of at least 1.5dB using more than 4m of 4.5m dish (beam-width ≈ 0.21deg) compared to 3m dish at LX1DB.
