Два новых передатчика не прошли тест на стенде и сгорели примерно через 20 минут после включения. Причина - выход из строя оконечной микросхемы передатчика и последующая перегрузка вторичной цепи питания 5в, после чего передатчик перестает включаться. Во время теста у обоих температура по встроенному измерителю уходила за +70 градусов.
После замены сгоревших микросхем усилителей мощности в двух экземплярах передатчков были проведены доработки по облегчению температурного режима, может кому и пригодится -
