[Elecraft] Peaking L34 (IF amplifier)

[Don Wilhelm]

David,

Yes, the peak is VERY broad.  You may have to connect an AC voltmeter across
the speaker connector to find the peak if you cannot discern it by ear.  The
peak is normally 1 to 1 1/2 turns down from the top of the can.  Be certain
you are using CW mode.  If your peak is right at the top of the can, check
the value of C182.

73,
