2.4Ghz LNA, test's failures, and finally == worked. (20км связь через Блутюз)

2.4Гиг блутюз как главный канал связи для лунного проэкта команды План б.
Тесты, попытки разобраться что не работает, дизайн, предизайн. И наконец удача - ошибка найдена - кусок провода был не кооксмальный а микрофонный - печесчет импеданса - перепайка 4 кондеров-индукторов - и связь 1 милливатного стандартного блутюза подхвачена в тесте сначала на 2.7 км, затем 4км, предыдущие тесты дают уверенность утверждать сигнал будет приниматься на 20км прямой видимости.

Test includes standard BlueTooth transmitter/receiver 1mWt (0 dBm) and second device (LNA with cascade 3x12 =36 dB, transmitter 6dBm 4mWt). "Standard 0dBm" transmitting signal needs to be picked up from 10km. At the same time "standard -- receive" will be picked up from 4 km. Two persons with cell-phones call each other and confirm communication session by looking on a blinking LED. LED blinks only when proper packet was received and processed (including restoration of noisy packets from different BT and WiFi transmitters in urban environment). Noise also has to be suppressed from cell-pones stationary transmitters (on top of SFU hill and QE park at Vancouver).

Even to do test on 10km was not necessary. Signal received by standard BT from 6dBm was picked up on 4km, and according "rainy test" that mean antennas-amplifiers system must to pickup signal over 20km which is more than it was expected.
