RW3DF: Сперва было желание работать в категории –отдельный передатчик. Для этого был добавлен каскад на КТ603 к передатчику на одном транзисторе ГТ308. Выходная мощность при 9в стала около 200мвт. Накануне, в пятницу, с ним удалось провести 2 связи. Однако в первый день научной игры за 3 часа никто не ответил. После чего перепаял провода и подключил батарейку на MTR-3B. Ожидал, что ее хватит на 3-4 связи. Но ее хватило на два дня. К концу первого дня напряжение просело на 1в. На второй день напряжение упало до 7,6в. Проведено 11 связей. Результаты были бы выше, если бы не магнитная буря. Пришлось ее переждать и во второй день первую связь провести в час дня. Второй фактор – бойкот ряда станций из Восточной Европы – 9A, LZ, LA, PA, OZ. Очень рассчитывал, что будут связи с восточной стороны России, но только одна связь с Поволжьем, а Урала и Западной Сибири не слышал.
YU7AE: very limited time to activity, only sunday QRV. on 20m is weak propagations, 2 el. Steppir is little help, 1 QSO in log. On 40m is nice propagations for QRP, 7 QSOs in log (3 more QSOs after activity, battery still working). Rig on 20m is Rock-Mite 20 trcvr (Xtal controled, 2 freq 14.059.9 and 14.059.0) antenna is 2 el.Steppir at 10m agl. Rig on 40m is Miss Moskita digital 40 trcvr (DL QRP kit) DDS vfo , agc, cw filter, elkey..... antenna is is Inv V trap dipole (like W3DZZ with 30m wires). Key is VK3IL sota pressure paddle.
YO8AZQ: very QSB. I worked with PA3EWP, II9IABJ, J43ND
RX3G: Only 2 QSOs but ER2GF is new Country for me QRP and QRP-X. Thanks!
