Re: Quark FALCON 1000 KW FM Transmitter - Alarm LED illuminated
Weird they went for a third party first instead of going straight for warranty service.
Do they have a spare transmitter? I would hope they would... It's a pity RF transistors are so fragile... |

Re: Quark FALCON 1000 KW FM Transmitter - Alarm LED illuminated
With a sufficiently bad impedance miss-match it is quite possible to have very high voltages coming back down the feed line, this tends to be what causes damage in a high vswr reflected RF scenario.
