Fwd: [ELECRAFT] K3s KIT low audio in speaker and phones

[Olaf Matthaei]

I build the K3s kit 10089 , all fine but I have low audo in speakers and
phones.
That means audio is beginning to hear on 3 o' clock position of AF gain
dial.
I AF gain is in the 5 o'clock position, autio is readable but distorted.
RF dial is in the 5 o'clock position.

AGC-fast
AGC-SLP 12
AGC-THR 05
SPKRS 2
PKRS+PH no (and PH.R SW-)

I checked the (2010) schematics, AF  amplifier for SPKR an PHONE is the
DSP board. There is nothing after the amplifier that can distort the
audio signal (only switches and outlets).

My DSP board is revision E (schematic: ref C).

Receive of RF is as expected (well in P3).

Olaf,

This is definitely not normal. Please describe your symptoms to our customer support techs so they can give you a few simple things to check. One possibility is that the crystal filter offsets are not set up correctly. The offsets are marked on the filters (except 0.00 for all Inrad filters), and data can be viewed/changed in K3 Utility.
