I have been having a problem with my FT-847 transceiver output power being
folded back when driving a SB-220 in SSB mode due to erratic SB-220 input
SWR. The input SWR of the amplifier is varying between 1:1 and 5:1. As the
SWR increases, the power of the transceiver reduces due to the automatic
fold back circuits and therefore amplifier output power reduces accordingly.
If the transceiver is set to CW then SWR is 1.2:1 and amplifier produces
full output.
My previous TS-830S exciter always produced correct output ... but it didn't
have any fold back circuits either.
Is this a normal situation using solid state exciters?
Thanks for any comments.
