Eric Swartz was very clear about this in a message to this group yesterday:
"Component failure like this can occur in any manufacturer's radio or amplifier for many reasons, such as power line surges, nearby lightning strikes, operating with excessive SWR, transmitting into a wrong antenna etc. You do not need to be operating on a particular band, or even have the amp or radio on to incur lightning damage. This can also cause partial damage to components that then shows up as a failure later after additional operation.” wunder K6WRU Walter Underwood CM87wj http://observer.wunderwood.org/ (my blog) > On Nov 13, 2015, at 9:57 PM, Vic Rosenthal <[email protected]> wrote: > > But why would a filter for a band that the operator had never used fail? > > Vic 4X6GP/K2VCO > >> On 13 Nov 2015, at 11:52 PM, Wes (N7WS) <[email protected]> wrote: >> >> Why would one filter, that like just like all of the others is switched into >> the circuit by a relay on each end, fail while none of the others do not? >> >>> On 11/11/2015 1:32 PM, Jim Brown wrote: >>> >>> The LPF is on the output of the amplifier.
