Yes, I noticed a comment on that issue. If you listen to the 1260 clip I think it's quite obvious that there is no HPF involved. The spectrum drawn off the recording in Audacity is identical to the HDSDR spectrum. Actually I would set up a modest HPF myself if I were to process the audio.
Tnx Bjarne!
ReplyDeleteCould you confirm AM audio response below 200Hz?
It seems all modern Icoms have a fixed audio HPF, cutting off true bass for AM broadcast.
