[Amps] SB-1000 tuning question

[Carl]

Is that tuned into a dummy load or an antenna of unknown impedance? If 
the latter then its simple to juggle fixed padder values.

Im one who pays little attention to low band VSWR under about 5:1 with 
dipoles in particular and adapt the amps to the antennas.
