Do not tell me, tell Ameritron! My QSK-5 has been working flawlessly for 10
years. I even use it mobile @ 1 kw. A man asked a question, and I gave him
an answer, direct from the Ameritron manual. The QSK-5 meets all of its
specs without raising any voltages due to increased vswr. Ameritron will be
glad to know that they have been living a lie with a bad product all these
years.
