...I built several early production SSB's in which RFC1 and RFC2 were mounted flat against the bottom of the board, in fact, the silk screening for them still exists there on the bottom of the latest boards...I don't remember reading anything about why they were moved to the top, but there must have been a reason...?... ---------------------------------------------------------------------------- Asked Gary at Elecraft only about a week back the same question and he told me the toroids need to be on the top to prevent interference with the varactors in the CW IF filter, and to prevent additional signal leakage or signal pickup. Have a feeling mine are on the underside as the screen printing shows, so will move them if they are when next inside the K2. Will also compare the Spectrogram responses between the two methods to see if there any difference that can be seen there.
